To Kill or Not to Kill

I have been in Utila for three weeks now and there has been a steep increase of the amount of mosquitos in the last week and a half. Unfortunately this has led us to being attacked by swarms of mosquitos when we have been outside. I have started wearing bug spray all day and night and I am still am covered in hundreds of little (sometimes not so little) itchy red bumps. The worst part is this is just the beginning, as we move into the rainy season it is clear that the mosquitos will be going nowhere any time soon. Many wishes for all the mosquitos to die have been expressed by all so I decided to do a little research into what is being done to control or eradicate mosquitoes and people’s views about the impact it will have.


There are 3,500 named species of mosquitos but only a couple hundred or so bite or bother humans and of those couple hundred only 30 or so species are the real problem. These mosquitos can carry many viruses and diseases that have a heavy impact on humans including malaria, yellow fever, dengue fever, West Nile virus, and chikunguya. The ease and the rate at which the mosquitos can transmit these diseases among people causes millions of deaths a year and heavy medical and financial strain on countries. Causing a species wide extinction, specicide, is being researched and would save many lives and allow developing countries to use their money on getting food and clean water to more people. The many benefits to having mosquitos eradicated are easy to see and when you are fighting a swarm of mosquitos, specicide of them seems like it would be the best thing to ever happen on the planet. However, some scientists are not for the total eradication of mosquitos.

Life in the Artic could be heavily impacted by specicide of mosquitos, some scientists estimate that up to 50% of migratory birds in the tundra would die out without mosquitos. Also caribou herd paths are influenced by swarms of mosquitos and without them the paths and behavior of the caribou could change and cause severe impacts on life in the tundra. There are also animals that specialize in mosquitoes such as the mosquitofish and in the absence of their food source, will also go extinct which could impact the food chain. Opposing these scientist are ones arguing that mosquitos specicide will have no impact on the food chain. It is argued that we have overestimated the amount of mosquitos that animals eat and an examination of their stomach contents has proved this point. They also believe that animals that do target mosquitos as prey will switch to other insects. Aside from animals, plants would be impacted for many of them would loose their pollinators but none of those plants are ones that humans depend on so these losses are mainly being overlooked. One scientist is fighting for not the total extinction of mosquitos but a temporary disappearance of them in order for diseases such as malaria to disappear and then to reintroduce mosquitos. What the impact will be is unknown but some scientists fear a major disruption of the food chain and some think that there will be just a small hiccup and then either some other species will fill the niche or nature will figure it out.

Even with all the possible negative impacts of the specicide of mosquitos, the majority of people are in favor for it because the benefits from it are so great for the human population. There are many scientist that are working on how to cause such an extinction, while some are focusing on all mosquitos there are many that are focused on just getting rid of the 30 or so mosquitos that cause so many problems for the human population. Currently there are some pesticides that are being used to control mosquitos and they are specific to different life stages of the mosquito. Larvicides target the larvae and kill the mosquito before it matures into an adult. These larvicides are mainly an oily substance that is applied directly to the water and disperses forming a thin layer of oil on the surface of the water. This causes the larvae and pupae to drown because they cannot penetrate the oily layer. It also deters adults from laying eggs in that body of water. Adulticides target the adults and are sprayed from planes and trucks causing the fine aerosol droplets to cover a large area and kill the mosquitos on contact. Personal mosquito control includes the use of bug spray and it is also recommended that you get rid of any standing water around, to change the water in birdbaths regularly, and to properly maintain pools. No matter what your view is on this issue it seems inevitable that sometime in the future mosquitos will no longer be a bother and so while we wait for them to figure out a method to cause the specicide, bring on the bug spray and the anti-itch cooling gel.

How has tourism changed local perceptions of the ocean?

Utila’s first dive shop opened in 1991 and twenty years later there are over 10 dive shops and resorts. The growth of this dive industry and the low price of an open water course has lured in many budget travelers to the Caribbean island. As tourism increases on the 11km long island it leads to an influx of mainland Hondurans coming to Utila along with dive professionals from around the globe for work, which has led to the population increasing exponentially.


Tourism has its positives and negatives for the island but I wanted to look into how it has changed the opinions of Utilians as they witnessed this change firsthand. I spoke to a few locals who work at the Bay Island College of Diving (BICD) and the Utila Lodge ranging in age from 20 to 50 and their answers were as follows:


Albert is a captain at BICD and the increase in tourism has changed his opinion of the ocean. He now realises the importance of keeping marine animals alive rather than fishing them for food. He used to catch and eat turtles every other month with the meat lasting a couple of weeks for his family. He hasn’t eaten turtle for fifteen years. Albert also used to fish regularly for lobster, conch, crab and other fish. He now cannot remember the last time he ate lobster. This benefits the reef and the tourists who are more satisfied after seeing an abundance of marine life. Having a job in tourism also makes Albert more money and is more rewarding than the jobs he used to have, for example working on freight ships. If he got offered another job today he wouldn’t take it.


Another boat captain, Foster, has realised since tourism has become a big part of Utila the amount of garbage in the ocean has reduced. If the aesthetics of the ocean were gone then so would the tourists.


John, a dive instructor at BICD is only 20 and is already doing his PADI Staff Instructor qualification. He became a diver as the income it brings him is a lot better than a job he would have on the island if tourism wasn’t so big. Tourism has changed his life and career.


Queen Anne (or Queenie as everyone calls her) has been working at the lodge for over ten years. She has noticed that as more people have come to the island everything is being destroyed. She mentioned that when she was growing up here they used to have everything in abundance because they took care of things in the ocean. For example, when they caught a female lobster and saw she had eggs, they would put her back. Now this isn’t the case as fishermen are taking anything they catch regardless of size or reproductive stage and people do not care anymore. This is an indirect consequence of tourism as it isn’t the tourists but some of the community from the mainland who have different beliefs and cultures than those from the Bay Islands.


Another dive instructor at BICD, Donna, says that she has become more aware of ocean topics since becoming a diver. For instance she had no idea about overfishing and has now noticed the decreased amount of reef fish on dive sites. Donna also said that the tourism has changed Utila’s culture and people, especially her, as she is more open minded to what is going on in Utila. She has noticed that tourism is just a money making business and people aren’t taking care of the reef.


These are just five peoples’ accounts of tourism on Utila and their stories all differ. Although most are more conscientious about the ocean there are still those who continue to fish as they did decades ago, catching turtles, which are endangered, and other species which have a minimum take size. Some continue to take what they want without realising that the species are what bring tourists to Utila. This is just an example of one island in the Caribbean, but this is happening worldwide, and hopefully one day we will all realise the importance of the ocean. If we nurture the environment it will nurture us.

Ocean Motion

The polar regions are important drivers of the world’s climate. Ocean currents redistribute heat around the world via thermohaline circulation (also called the Global Ocean Conveyor). One reason water in the Global Ocean Conveyor circulates is because of differences in water density. Differences in temperature and salinity are the cause of changes to water density. The colder the water the denser it becomes. Same with salt, the saltier the water the denser it becomes.

The greater the density difference between separate layers in the water column, the greater the mixing and circulation. Water heated near the equator travels at the surface towards the poles where it becomes cooler. As the water cools, it becomes denser and sinks into the deep ocean, driving the deep ocean currents. When salt water freezes the salt is excluded. When water freezes at the poles the surrounding water becomes saltier and sinks, this also contributes to ocean circulation.

Melting of polar ice could cause dramatic changes to the Global Ocean Conveyor. As the earth continues to warm and arctic ice melts, freshwater is released from melting ice, making seawater at high latitudes less salty, therefore less dense. The less dense water will not be able to sink and circulate through the deep ocean as it currently does. Therefore this melting of arctic ice has the potential to disrupt and slow the Global Ocean Conveyor. The warmth from the warm surface currents carried away from the tropics is lost to the atmosphere.  The slowing of this ocean circulation could lead to a cooling in places where this warmth is currently lost into the atmosphere.

So why does this matter for the small island of Utila? When fresh water flows into the sea it changes ocean currents, which changes living conditions for marine organisms. These changes will be noticed everywhere around the world. Many marine animals depend on these currents for migration. They depend on these currents to find food and for breeding purposes. A change in ocean currents could change the distribution of phytoplankton, which would change migration patterns of larger organisms that depend on such distributions. A change in heat distribution could cause problems as well. The warmer less nutrient dense water will stay concentrated in the tropics, which will cause further changes to the marine organisms found here.

The Importance of Biodiversity

Late last year the World Wildlife Fund (WWF) released a report via its biennial Living Planet Report for the year 2014. The results of the science based study were quite sobering. The Living Planet Index (LPI), which measures trends for more than 10,000 representative populations of fish, birds, amphibians, reptiles, and mammals, declined by 52% between the years of 1970 and 2010. More than half of Earth’s biodiversity lost within the relatively minuscule time frame of 40 years. How did this happen? What are some of the contributing factors responsible for this staggering decline in biodiversity? Furthermore, why is it so crucial that we put forth our best efforts to conserve as much of it as we possibly can?


So, just what exactly is meant by the term biodiversity? The term biodiversity is relatively new and is thought to have first been coined by W.G. Rosen as a contraction for “biological diversity” back in 1985 and it first appeared in a 1988 publication by sociobiologist E.O. Wilson. Simply stated, biodiversity is the variety of all the different forms of life found on Earth.


There are many factors that influence changes in biodiversity. These factors, which can be either direct or indirect, are referred to as drivers. Some of the main drivers responsible for this loss of biodiversity are climate change, overexploitation of species, introduction of invasive species, habitat destruction as a result of urban sprawl as well as for the purposes of agriculture in order to meet the demands of an ever increasing human population, and pollution just to name a few.


So why is maintaining biodiversity through the conservation of species so important?


Well, for starters, ecosystem productivity is higher when more biologically diverse. More biologically diverse ecosystems can also prevent and rebound from natural or man made disasters more readily than those systems that are less diverse. The human population depends on them for resources such as food, shelter and medicine. In some areas of the world the economy is based largely upon ecotourism and if those avenues of income were to suddenly evaporate due to losses of biological diversity those economies in all likelihood would go belly up. History is also replete with examples of how the discovery and subsequent study of organisms have helped advance the fields of science, engineering, and medicine.


Whether you view a species as having an “Intrinsic or inherent value” (something having value in and of itself) or you view it as having an “instrumental or utilitarian value” (the value something has as a means to another’s end), one thing is for certain and that is that the value in having rich biological diversity is immeasurable. After all, who wants to live in a biologically depauperate world anyway? I know I most certainly do not.

Conservation and Aesthetics

Which species deserves to be conserved? One could argue that all animals facing extinction should be saved, as each play an important role in the entirety of the ecosystem. However, as the scientist David Stokes recently wrote in the Journal of Human Ecology, ‘human preferences will increasingly determine many species’ prospects for survival‘.


Humans are not always able to make an emotional connection with a species, increasing the possibility of that particular species being neglected. An animal’s aesthetic appeal is what generates greater interest to make it desirable to be saved. The public is able to connect with some iconic animals by finding them majestic and powerful like the polar bear, cute and fluffy like the panda bear, or cool and chill like the sea turtle. Some species have an influential visual or symbolic charisma, garnering more support from the public to further conserve them.


There have been studies exploring which visual characteristics of certain species humans prefer, and how this affects the attitudes towards its conservation. One particular study focused on evaluating which parrot species were found in captivity. The study found that there was a ‘positive association between perceived beauty and the size of the worldwide zoo population‘. Other variables analysed included the International Union for Conservation of Nature (IUCN) listing, which was shown to be an insignificant variable. The study concluded that the conservation status of the particular parrot species was not the determining factor; instead it was the parrot’s aesthetic appeal.


So if a species is less desirable in the eye of the general public, how do we change the species’ future outlook? There have been recent outreach initiatives bringing awareness to the neglect of less appealing animals by conservation efforts. Will educating the public on the importance of conserving keystone species, generate a greater interest in those species previously deemed ‘unappealing’?

Don’t forget to look on the bright side

When you work in the field of conservation even for a short amount of time your eyes are quickly opened to the perils facing the natural world. From habitat loss to global warming, humans are having a huge detrimental impact on all life on our planet. Seeing these impacts first hand and then researching and finding out more about these complicated and intricate problems can sometimes be quite depressing.


Many of the problems facing the earth right now require an immediate change on a large scale. Much to the frustration of conservationists, this change is taking a long time, with the impression from many that a ‘point of no return’ is coming in the near future. This leads to people seeing conservation as a lost cause, a point of view that can derail the entire conservation effort. If you can’t see hope then there will be no will to change.


Conservation scientists tend to promote awareness of issues by calling attention to worst case scenarios (for example, ‘if nothing is done, this species will be extinct within x number of years’). It is important for people to understand that while conservation issues are important and shouldn’t be ignored, we should not get blinded by a sense of impending doom, or a ‘what’s the point?’ attitude.


Conservation exists because a difference can be made in the world and it has. The problem is that if you focus too much on the negatives it can eclipse all the positives happening out there. This happens frequently when people forget a problem after it has been resolved to focus on the next issue. It is important to celebrate these victories in conservation and not gloss them over. There are people working very hard whose efforts are paying off.


The fact that there is hope out there should not be forgotten. Species have been brought back from extinction, massive natural protected areas have been created, and giant potentially destructive mega projects have been derailed because of their potential negative ecological impact. The power of the few cannot be underestimated, something that shouldn’t be overlooked, especially by conservationists.

Utila Time

I have now been at WSORC for ten weeks. Upon arriving in Utila, I did not quite know what to expect. But as soon as I dropped my bags, I was immediately plunged into an amazing atmosphere that has created countless and unique memories. Here is a look into my experience here at the Whale Shark and Oceanic Research Centre…


I arrived on the 6th of June, ready to learn and experience life working for an NGO. After settling into our house, it was time to begin the internship. The first week comprised of presentations given by our program coordinator and the Research Assistants (RA). This, along with a tour of the island and general introductions to the many people who I would grow to adore, was a lot of information to take in. We had activities such as visiting the freshwater caves on the island. We participated in our first of many beach clean-ups, where we experienced the devastating impact of plastic pollution. Everyone enjoys taking part in the beach clean-ups, you spend a morning on a beach, with great people, and best of all, an amazing lunch made by a resident restaurant owner.


After the introduction period at the beginning, the Marine Conservation Interns started their diving courses, while I and a Dive Master intern started to develop our fish identification skills by diving the reefs and taking along slates and pencils. This gave me the opportunity to fall in love with diving even more, as I spent all my bottom time looking for the smallest fish and naming them, like the juvenile French Angelfish, probably my favourite juvenile fish. After taking an exam, all of us became certified Reef Environmental Education Foundation (REEF) surveyors, and contributed data to a multinational database run by the REEF foundation.


At the same time I leant to undertake diver impact surveys, which consists of following divers and taking note of the times they come into contact with the fauna underwater. This has made me pay attention to my diving, as hitting a coral with your fin can damage it, and it will take a large effort and countless years to rebuild itself. I have to admit it is fun being the “diver police,” but with power comes responsibility.


During the first month I was also introduced to Ocean Safaris, which are the trips where we go looking for whale sharks and other megafauna. As an RA, I would eventually be running these, so it was important for me to see the other RAs in charge, organising the boat, and acting as the leader with customers. Sadly in my ten weeks here, I have yet to see a whale shark, however I have had several great encounters with spinner and spotted dolphins, in particular the day we swam with roughly 80-100 dolphins, jumping out of the water and diving under us. That was an amazing experience. Speaking of notable animals, I have also had the fortune to meet the nurse sharks that live on the North side of the island, and the endemic swamper iguanas.


After my first month, the group of Marine Conservation Intern (MCI)  that arrived with me departed the program, so it was time to start being more autonomous, as I would be helping to train the next group of MCIs. In our down time, before the new arrivals, we planned out the activities of the month, and more importantly of the first week, as myself and the other two RA’s would be running the centre independently, which was very exiting because it allowed us to be part of all the behind-the-scenes operations.


The second month was a great experience, and the whole team had a lot of fun, especially during the annual Utila Carnival. During the boat parade, WSORC and Bay Islands College of Diving, our partner dive shop, paraded our boat represented with pride. For the float parade we danced the streets all dressed as marine animals, with myself as a lobster, and the girls all dressed as mermaids. I started assuming more responsibilities at the centre, such as running the welcome desk a few times a week, and leading the new interns on their fish ID dives and transect surveys. I learnt a whole lot that second month, like which are the best places to have dinner (my favourite being the asian restaurant: Foo King Wok).


If I am describing my experience here on Utila, I cannot leave out the fun times I have had. The big group of 15 that we once were had several hilarious nights out at local bars Tranquila and Coco Loco, and great times taking a boat to a tiny island with palm trees and hammocks. I also cannot leave out the fun times i had riding around the island in an ATV. As you can see, I could go on and on naming fun times, but that would take too long…


Now I only have four weeks left, which on Utila time, flies by in the blink of an eye. I am currently creating a lion fish spearing workshop, which hopefully will teach others to spear lionfish responsibly.  I am super happy to have been given the task, and to be trusted with running it in the coming weeks. When my last week comes around, however, I will be sad to be leaving this wonderful island, its amazing people and atmosphere. I will be leaving to go back to university, but coming back will not be out of the question, who knows…

Paradise Lost?

As I write this, I have three days left in my internship at the Whale Shark and Oceanic Research Center. I’ve had some wonderful times here, between fighting off an overly curious moray eel, guiding newly-hatched hawksbill turtles into the ocean, and just experiencing life on Utila. But I will leave with one regret, and it’s not that I haven’t seen a whale shark (though I still have one more chance!). My only regret is that I didn’t get a chance to visit 40 years ago when, from all accounts, the reefs were pristine, the fish were bountiful, and the impacts of human development had yet to take their toll.


Decades ago, the reefs of the Caribbean and those in Utila were among the most biodiverse in the world, covered with an abundance of corals and fish to rival anything in the Pacific. The underwater world encountered by the first scuba divers must have been truly awe-inspiring, with an innumerable variety of brilliantly colored corals, all different shapes and sizes, covering every possible surface. Enormous schools of fish, so thick you couldn’t see through them, swirling around every surface, impenetrable but for the holes that sharks bored on their way through the wary swarms. In the minds of many, the Caribbean still looks like this, a result of center spreads in travel magazines and underwater photographers visiting the best, most pristine sites. However, decades of mistreatment, overharvesting of resources, a few region-wide catastrophes, and simple negligence have taken their toll. Much of the Caribbean doesn’t look like the movies anymore, and Utila is no exception. Coral covers are down, algae obscures their brilliance, and sharks, considered an indicator species for the health of a reef, are a rare sighting here. Even groupers and large snappers can be a difficult find on the more well-travelled south side of the Island. So what happened?


Much of what ails the Caribbean can be traced first and foremost to the degradation of corals. Coral cover in large parts of the Caribbean today is as low as 15-20%, a far cry from the 90% often observed in the south Pacific. This disparity is due to a range of factors, but the first blow was dealt by the Diadema die off in the early 80’s. The long-spined sea urchin, Diadema antillarum, may to some be merely a hazard for swimmers and divers, but to the reef it is a crucial grazer, eating algae that would otherwise outcompete and smother the slower-growing corals. Unfortunately, an extremely virulent and still unknown disease swept through the Caribbean in 1983, killing up to 97% of the Diadema urchin population. Diadema densities are only now beginning to recover. The die-off led to many reefs becoming overgrown by algae, while other grazers such as parrotfish were able to pick up some of the slack, the effects of this die off can still be seen in every mottled brown piece of coral.


Another, and in my mind the most enduring, problem to face Caribbean reefs is overfishing. Utila in particular has been hit hard by having too many lines in the water. While only 7000 people call Utila home, few enough that the reef could conceivably support a sustainable local fishery, Utila exports much of the fish caught here, with most going to the US. The explosion in fishing that occurred about 20 years ago, when Utila began exporting fish year-round instead of only a few months a year, combined with a local fad for catching grouper, has demolished populations of large, sought-after predators, with large predatory fish often difficult to come by at many south-side dive sites. This has had an effect on every organism lower down the food chain that calls the reef home, an effect known as the trophic cascade. As the predators disappear, it destabilizes the populations of the fish that they eat, which in turn destabilizes the populations of whatever they eat, causing everything to eat too much or too little of each other and ultimately doing incredible damage to the reef ecosystem as a whole.


The final curse to befall the Caribbean is the invasion of Lionfish. Lionfish are a ravenous, venomous, and all around nasty predator from the Indo-Pacific that are thought to have escaped from an aquarium in Florida in the 90’s and never looked back. Small fish do not recognize the lionfish as predators, attempting to hide in the predator’s spines before being devoured, and large predators do not recognize them as prey, with scant evidence of groupers and sharks hunting them in the wild. As a result, these colorful little demons have taken over reefs from the East Coast of the US all the way down to the Northern shores of South America. The saving grace, however, is that lionfish are delicious, as we at WSORC can all attest. From the Florida Keys down to Bonaire, experienced scuba divers have been spearing them with minimal impact gear, and eating them, selling them to local restaurants, or just getting them out of the water. When done responsibly (Don’t touch the coral. Ever. With any part of your body. Just don’t), it has proven to be an effective method of control, and is practiced here at WSORC. Here on Utila, lionfish are essentially non-existent on the south side of the island. However, spearfishing cannot control lionfish at more remote sites or at depths exceeding 40 meters, the recreational dive limit. It is my hope, however, that as lionfishing grows and matures as a practice and native fish begin to learn how to deal with these foreign predators, the lionfish invasion can be controlled better in the future.


Throughout this post I’ve mentioned the south side of the island. This is the side with the town, the main road, all the dive shops, and all the development and boat traffic. The south side is therefore the most impacted by humans, and home to the least healthy corals. It is the reality, and some fear the future, for much of the Caribbean. The north side, however, is another story. Its coastline is undeveloped, its waters are protected, at least in name, by the Turtle Harbour-Rock Harbour marine sanctuary, and its corals are fed by upwelling currents. Diving the north side is like stepping back in time, as if the surface of the water were a portal taking you to another age. Snappers school, corals cover the walls of drop-offs, clinging to every imaginable surface, and reefs teem with fish, sea turtles, and even a nurse shark or two. It is a reminder of what we have lost, but also of what can be again in the future. The most astounding thing about nature, what truly takes my breath away, is that the second we stop actively making things worse, it usually starts to get better on its own. If Utila were to enforce and expand it’s marine park, reduce fishing pressure and development, and get more divers on board with conservation, the future could look more like the North side than people think.


Call me an optimist, but I think there is reason to hope. The Utilian economy has already shifting towards tourism instead of fishing, and local restaurants and dive shops are at last beginning to talk about sustainability. While the freight train of climate change is barreling towards fragile coral reefs like ours, healthier, more diverse reefs and those in cooler waters, such as the north side, will be better equipped to deal with changing ocean chemistry in the future. So, as I sit here, about to leave paradise, I take nothing with me but memories, and the hope that paradise will still be here, better than ever, when I get back.

Why the ocean matters

I have been reading a book by Alanna Mitchell entitled “Sea Sick” that discusses various ecological crises at different marine locations around the world. There was a line in the book that read:


If all life on land were to vanish tomorrow, creatures in the ocean would flourish. But if the opposite happened and the ocean’s life perished, then the creatures on land would die too”.


This made me realize that not everyone may be aware of how vitally important the oceans are for human survival. This is not just a concern that is limited to marine conservationists and environmental activists, but something that should be of concern to every single person on this planet. Many people tend to have the view that the ocean is only there to provide us with endless supplies of food or and travelling routes to new places. It’s believed that the planet’s vast resources will always be there and it will be resilient enough to compensate for whatever human’s are doing. It is important that everyone understands how the ocean is supposed to work so we can then understand how our actions are damaging it, and what the implications of an unhealthy ocean actually are.


The oceans cover 72% of the planet making it the largest ecosystem on earth and it is responsible for controlling the temperature, climate and key chemical interactions with the atmosphere. Phytoplankton (photosynthetic organisms that live in the surface waters) are responsible for producing more than half the oxygen in the atmosphere that we breathe, but get little recognition for their contribution. You probably think of trees and the rainforest as the largest oxygen producer for the planet, but you can thank the chlorophyll containing microalgae for that title. There are multiple threats to phytoplankton (ocean acidification for one), which would cause a decrease in the world’s breathable air by 50%.


Further to that effect, another important chemical process the ocean performs for us is removing carbon dioxide from the atmosphere, which if disrupted, can lead to ocean acidification. The oceans are in constant equilibrium dissolving carbon dioxide from the air into the water, removing about one third of the carbon from the atmosphere each year. As the concentration of CO2 in the air increases, the concentration in the water increases as well. The addition of this carbon dioxide causes the water to become acidic and this devastating effect will cascade throughout all the marine ecosystems, ultimately leading to a large die-off of many creatures.


Even if you have no interest in the conservation of the ocean’s biodiversity, and don’t even like eating seafood, you should know that the ocean holds 97% of the earth’s water and provides 16% of the world’s protein. Phytoplankton are at the basis of all marine food webs, with their decline brings fish declines, coupled with overfishing pressures from humans there is a guarantee in global food shortages for millions of people. There are also many consumer products that contain materials from the ocean such such as peanut butter, ice cream, and toothpaste.


Finally, the ocean acts as a giant thermostat for the earth regulating local and global temperature and climate conditions. The global conveyor belt includes both deep and surface currents and plays a vital role in regulating weather and climate and distributing heat around the world. Winds and ocean water density drive the currents that carry heat from the equator to the poles, without it the tropics would be uninhabitable and the poles would be harsh frozen lands. With changing ocean chemical composition, these currents are subject to interruption and in turn changing the climate of the planet.


Whether you live near or far from the sea, the ocean affects everybody, it is the foundation to our lives and it is dying. The oxygen is being depleted, and acidity is rising, not to mention the added stressors that humans bring such as overfishing, and pollution. We are heading towards a mass extinction of marine organisms, global food decline and changes to our atmospheric processes. To put it simply, in order to live comfortable, healthy lives, we need healthy and happy oceans.

First impressions of Utila

Where can I even start describing my first few weeks on this crazy and beautiful island? I have fallen in love with Utila. I spent a couple of weeks here before I started my internship and had already decided Utila is a special place, but it has become even more special to me after just two weeks at WSORC.


I do not have a background in marine science or anything related but I have learnt so much already from the presentations, boat trips and generally being around such interesting people all the time! When I arrived at WSORC I began my Advanced Open Water PADI certification with my fellow volunteers, and got the opportunity to do a wreck dive – surrounded by thousands of tiny jellies at the three-minute safety stop being my favorite part, I have a newfound love for jellyfish! We also did a night dive, which I’ve been dying to do for ages – it did not disappoint, as well as seeing bioluminescence for the first time we saw a cute little octopus.


On one of the first days a group of us from the dive shop and WSORC walked to the freshwater caves, another new experience that was mostly enjoyable, other then the part where you had to squeeze through the tiny jaggedy tunnels! The caves were awesome though and you could swim into different chambers, as well as being surrounded by bats, which actually looked pretty beautiful in the torchlight. The next day we walked to Pumpkin Hill beach hoping to see turtle hatchlings at sunset – unfortunately the turtles decided to stay in that night but we had a productive beach clean up and even found a tiny filefish perfectly dried. On a more studious side, the four of us also had a REEF fish ID and invertebrate ID test, which we studied pretty hard for between daily activities using the WSORC flashcards – we all passed and I’m excited to actually be able to identify all the pretty fish I’m looking at on my first research dive. I’m also crossing my fingers for dolphins!


Utila is a pretty unique place, full of a collection of people who have realized they can live life so much better on a Caribbean island, incredibly delicious food, and spectacular sunsets – not a bad place to wake up in the morning. One of my favorite days was taking a boat out to Water Cay, a tiny deserted island straight out of a luxury travel magazine. We bought some beers, music and our happy selves and hung out in the ocean all day – perfection. Another great memory was the carnival opening day boat parade. The boat got dressed up all fancy, covered in palm trees like a jungle, and so did we! We paraded around the bay for a good couple of hours, dancing, laughing and checking out the other boats (ours was definitely the best!). So, all in all, I’d say my first few weeks on Utila have exceeded all expectations and like so many people on this island – I literally never want to leave!
