MCCR Impact 2019-23

Over the past 4 years, we’ve worked hard on what we do and are proud of what we’ve achieved so far. Read a small part below about our impact and click the link at the bottom to download the full report. 

We founded Marine Conservation Costa Rica in 2019 with a mission to work towards a healthier ocean through coral restoration, marine education and research. Our main project is to combat the deteriorating coral reef ecosystem in the Manuel Antonio area, we aim to restore this reef and educate the local community on how to preserve the ecosystem for future generations.

From our report, you’ll learn that, with 563 students reached from our local community and 1396 new coral colonies planted on our local reef. We are well on our way to making a difference, however, we could not have achieved this without our amazing staff, interns and volunteers. We thank you from the bottom of our hearts. Our supporters have put in 6020 volunteer hours.

But to make a difference to ocean health on a larger scale, we need your help….every little change that you can make will add up to a big difference! So change to eco-friendly products, shop sustainability, reduce your carbon footprint and support conservation projects, only if we all work together can a healthy ocean be a reality.

Thank you!

Georgia King and Katherine Evans

5x increase in Corals Outplanted to date

We reach the local community, directly, through our outreach to students in particular. However, many of our other actions indirectly assist the community where fishing is a vital part of their way of life. 

Since 2019, we’ve had 3,990 intern hours spent on coral restoration in particular. This commitment to the future of our oceans from volunteers around the world inspires us and we hope inspires many more too!

There are currently 3 ways in which we create an impact on the local marine environment, of which our largest project, the restoration of local coral colonies, is growing every year with the help of YOUR donations and our countless interns who volunteer their time to assist us in achieving our goals.

Our Mission statement reflects in everything we do, showing commitment to Sustainability and the Community; Our Oceans are important to our way of life and protecting them is our duty.

The Threat of Ocean Acidification

The Threat of Ocean Acidification

What is Ocean Acidification and its Impacts? 


social media intern

The oceans on this planet are facing a profound threat: ocean acidification. It poses a crucial risk to the delicate balance of life within marine ecosystems and to their structure. In this article, we will discuss the complex process of ocean acidification including what it is, what causes it, and the far-reaching implications it has for marine life. 

“Due to climate change, the ocean is warmer, more acidic and less productive today.”

The United Nations 

But What is Ocean Acidification?

Ocean acidification is the ongoing decrease in the pH of the Earth’s oceans due to the absorption of excess carbon dioxide (CO2) from the atmosphere. As atmospheric CO2 levels rise, a significant portion of it is absorbed by the oceans, forming carbonic acid. This acidification process disrupts the chemical equilibrium of seawater, leading to lower pH levels and higher acidity.

The primary driver of ocean acidification is the burning of fossil fuels, which releases CO2 into the atmosphere. This excess CO2 is absorbed by the oceans, altering their chemical composition. Deforestation, industrial processes, and other human activities also contribute to the problem.

Coral Reefs in Peril: Coral reefs are particularly vulnerable to ocean acidification. The increased acidity inhibits the ability of corals to build their calcium carbonate skeletons, leading to weaker, more brittle structures. Putting entire reef ecosystems at risk; threatening the multitude of marine species that depend on them for habitat and food.

Disruption of Food Webs: As foundational species like plankton and shellfish struggle to survive due to ocean acidification, entire marine food webs can be disrupted. This has far-reaching consequences for marine organisms at all levels, including commercially important fish species.

Biodiversity Loss: The cumulative effects of ocean acidification, combined with other stressors like pollution and overfishing, can lead to biodiversity loss and reduced resilience in marine ecosystems. This loss of biodiversity can disrupt ecosystem services that support human communities as well.

How does Ocean Acidification impact Marine Life?

Shellfish and Calcium Carbonate: Ocean acidification disrupts the availability of carbonate ions. Many marine organisms, such as molluscs and shellfish, require carbonate ions to build their shells and skeletons. Weakened shells make these creatures more susceptible to predation and disease, with potential ripple effects throughout the food chain.

Effects on Fish Behavior and Sensory Systems: Studies suggest that ocean acidification can affect fish behavior, including their ability to navigate, locate prey, and avoid predators. Altered sensory perception could impact the survival and reproductive success of fish populations.

But what can we do to help?

While the challenge of ocean acidification is significant, there are actions that can be taken to mitigate its impacts:

Reducing CO2 Emissions. The most effective long-term solution is to curb greenhouse gas emissions, particularly CO2. This can be through sustainable energy practices, reduced fossil fuel consumption, and afforestation.

Sustainable Fishing Practices. Managing fisheries sustainably helps maintain the balance of marine ecosystems and reduces additional stress on vulnerable species.

Marine Protected Areas. Establishing and maintaining marine protected areas helps preserve critical habitats, offering safe spaces for marine life to thrive.

Research and Monitoring. Continuous research and monitoring efforts are essential for understanding the effects of ocean acidification. Greater understanding of the impact of ocean acidification will help us in devising effective strategies to combat it.

A Summary of Ocean Acidification

In conclusion, ocean acidification is a pressing issue with widespread consequences for marine life and the ecosystems we depend on. By addressing its root causes and implementing sustainable practices, we can work towards protecting our oceans and preserving the intricate web of life they support. As stewards of the Earth, we have the power to make a positive impact and ensure the health and vitality of our oceans for generations to come.

A Deep Dive into Reefs: Why Protecting Corals Advocates for Human Survival

Pavona gigantea - Corals of Costa Rica

Coral reefs in Peril

Coral reefs, polar bears, pandas and sea turtles are adored across cultures and known as the poster children of climate change. While each of these organisms has a difficult journey of survival ahead, the ancient coral reefs have arguably been suffering degradation since the 70’s. Coral reefs have been around for some 50 million years, outliving the dinosaurs and witnessing the birth of all other forms of complex life. These organisms represent the beauty and interconnectivity of our world. They are the foundations of coastal ecosystems, their rainbow collages attracting a diverse interaction of plants and animals. Yet the recent decline and death of coral reefs sends a shocking message at what we risk to lose if business continues as usual.

Oceans Heating Up

It is common knowledge that ocean temperatures are heating up, and although this represents one of the many threats to these delicate structures it is far from being the only one. Corals are also affected by the pollutants that find their way into rivers and streams from pesticides used to maximize crop yield. In addition to these silent killers polluting the water cycle, habitat destruction from coastal construction and the overly extractive fishing industry threatens the health of reefs. Finally, maybe the most dangerous of all is our addiction to fossil fuel consumption and the smoky trail of carbon dioxide we humans leave in our backwash.

Although the ocean is able to absorb a quarter of carbon dioxide emitted, there are still consequences to our incessant gobbling. In this simmering hotbed our corals are surviving in, their first stress response is to dispel their food source, the algae. As they lose these plants and subsequently their coloration, the surrounding organisms also feel the loss as their food source depletes. The stressed corals turn a skeletal white, and as the bleaching continues, they eventually turn as gray as tombstones.

Pressure on the reefs

Though reefs thrive in coastal paradises where conditions are idyllic and picturesque, the beauty of these habitats is a double-edged sword. As demand for these utopias increases, so does the pollution and runoff from development and tourism. As more people develop in and around the tropics, the pollution which comes with development and human consumption also grows. With this logic, it is no surprise that coastal communities are among the first to feel the effects of climate change

While the climate crisis often-times feels like a looming catastrophe, protecting coral reefs would trigger a chain reaction in sustaining the local ecosystems both above and beneath the ocean.  The urgency needed to preserve the remaining survivors can be grasped by painting a stark picture of what our world risks to lose with the extinction of coral reefs. A coral-less future would mean 6 million reef fishers without work; a net loss of $9.6 billion dollars to the tourism industry; 1 million marine species with no place to live, spawn, or feed; coastal communities with no natural protection against storms, tsunamis, flooding, and erosion; not to mention the incalculable loss of potentially life-saving medicines researchers discover in these underwater medicine cabinets (Basic Information About Coral Reefs). In short, our world without corals is hardly even a world at all. What are we without the very life that supports our human existence?

Dark situation

With less than 50% of coral reefs already dead, these submerged skeletons serve as a foreboding message: to save the coral reefs is to save ourselves.We are at a crucial moment in history, and our response to  the climate crisis is pivotal, but passivity is the most dangerous option of all. 

Although our current situation may feel dark, resilience is our silver lining. Coral restoration projects are underway across the globe helping to stabilize reefs. Restoration efforts assist in maintaining the base populations of coral species, giving more time for corals to adapt to changing conditions. This type of recovery work, however, will not restore reefs to their pristine state. Instead it buys time for the corals to adapt. That being said, restoration is most effective in conjunction with fishing quotas, Marine Protected Areas, and individual actions.

So what can you do?

That being said, there is a wide range of behaviors you can do that can reduce your negative impact on our planet. The following list includes suggested actions that the coral reefs, polar bears, pandas, and sea turtles need from all of us:


  1. Participate in Coral Restoration

– Take part in a Coral Internship 

– Enhance your knowledge of marine life with a Coral Reef Research Certification

  1. Be a conscious tourist

– Use Reef Friendly sunscreen 

– Be a Responsible Snorkeler and Scuba Diver: Never touch or harm corals/marine life 

  1. Support environmentally friendly companies 

–  Purchase organic products 

– Buy from sustainable fisheries (or avoid eating animal products altogether!) 

  1. Measure and manage your impact

Calculate your carbon footprint

– Practice zero waste living and stop using plastic bags!

  1. Raise awareness 

– Talk with your family, friends, and coworkers about the climate crisis

– Establish sustainability action groups in your school/work and come up with solutions in your own communities

Climate anxiety – What is it and what can you do about it?

Climate anxiety – What is it and what can you do about it?

Climate anxiety? What are your plans for the next six years? Graduate college, travel the world, get a puppy, buy a house, get married, build a garden, start a new job, have a child, or maybe two? Six years is such a long time! Time that can be spent creating beautiful moments. But what if you had to fit the rest of your life in the next six years—six years and 317 days to be exact. How short would six years feel then? Would you live your life differently? If you had the opportunity to add more time to these six years, would you make smarter, more ethical, and sustainable decisions? 

climate clock

Climate Clock

The climate clock hangs high in Berlin, and New York City, counting down “how long it will take, at current rates of emissions, to burn through our ‘carbon budget’ — the amount of CO2 that can still be released into the atmosphere while limiting global warming to 1.5°C above pre-industrial levels. This is our deadline, the time we have left to take decisive action to keep warming under the 1.5°C threshold.” (Climate Clock) 

While the clock does bring needed attention, is not always positive.The countdown may bring awareness to the climate crisis and encourage sustainable living, but does the oversaturation in the news increase a sense of impending doom? That no matter how much plastic you stop using, the meat you stop eating, or the numerous protests you attend, nothing will make enough significance to reverse this ticking time bomb. If you feel stress or grief around the current climate crisis, you are probably experiencing “climate anxiety,” “a fairly recent psychological disorder afflicting an increasing number of individuals who worry about the environmental crisis” (Psychology Today).

If you are someone who experiences climate anxiety and is feeling a little lost or scared, try not to worry. You are not alone. There is an entire community experiencing the same feelings. As someone who experiences climate anxiety myself, I would like to share some useful tips to help lessen your anxiety. 

Make adjustments

I’ve made adjustments to my daily living so I can leave a positive impact on my planet. If you have not already, start by lessening your plastic and meat intake, use your car less and public transport more, and switch off your lights and water as often as possible. 

“But I already do all of this, and it does not feel like enough.” 

While your individual acts are extremely important, I can understand those small changes might not feel overly impactful. Let me remind you that your small acts are making a huge difference, so take pride in that! Keep up the good work, and share your knowledge with those around you. Also remember, it is not the individual person that is having the greatest negative impact on our planet. It is the large-scale corporations that cause detrimental environmental damage. We need to continue holding them accountable. 

Fast fashion

fast fashion

You can start by limiting how much you shop from fast fashion companies. Fast fashion, “an approach to the design, creation, and marketing of clothing fashions that emphasizes making fashion trends quickly and cheaply available to consumers”,is a massive polluter, creating cheap clothing, at the expense of underpaid workers. Clothes not meant to last to the next season end up in our landfills. Fast fashion produces excessive amounts of greenhouse gases into our atmosphere and pollutes our waters with dyes and chemicals. 

Support small, ethical businesses and most importantly shop second-hand whenever possible. 

Try buying groceries from local farmers and markets whenever possible. Corporate farms tear down large sections of forest to make room for livestock, among other harmful practices. I would also recommend shopping organic to avoid harmful pesticides. The use of these chemicals overflows to waterways and is harmful to fish. 

When these practices aren’t an option, look for companies that have green policies—companies that pledge to offset their carbon footprint, or create products that are environmentally friendly. 

Your voice is your greatest strength. Hold corporations accountable for their actions. We need to demand sustainable initiatives, and if companies refuse to upgrade, then we must take our business elsewhere. 

Be positive

It can be extremely anxiety-inducing to have no idea what our future is going to look like. Especially when countdowns like the Climate Clock can make us feel like we are running out of time. I want to encourage you to look at this situation as “glass half full”, we have six years. Six years to change our daily practices. To live a zero-waste lifestyle, to stop eating meat, to buy only from small, local, sustainable businesses, and to stop supporting large corporations. Six years to reverse the damages done to our planet. We still have the chance to encourage change and make a difference. We have the opportunity to be the change we want to see in this world.

How green is your packaging? – 6 common misconceptions busted

How green is your packaging? – 6 common misconceptions busted

With the world changing we have been forced to reevaluate our way of life. One of the biggest things that has been brought to the forefront is the impact our daily habits have on the health of our planet. Seeing such a sharp change once everyone was in lockdown has made it even more clear. If the earth and nature is given a chance it will fight back.

Over the next month we are going to have a look at how covid has put living a sustainable life in focus. We work everyday to live a sustainable life, but with different information being presented all of the time it is hard to sometimes keep a clear path. Starting on this topic we are looking at one of the most common things we deal with everyday, packaging, and we are addressing 6 common misconceptions about “green packaging”.

Plastic is the bad guy of packaging

plastic packaging

Ban single use plastics has been a common anthem of anyone aiming to live a more sustainable life. The big one of these is plastic bags. Interesting fact, they were originally invented as a reusable carrying source, not intended to be used once and thrown away. But did you know that single use plastics can be more sustainable depending on the material it is made from? Also, how it is used and where it ends up. It actually has a smaller carbon footprint than say a canvas bag . That would have to be used up to 300 times to have a comparable impact. Also, by packing something once, properly in plastic rather than using less effective means of packaging could result in the item being damaged to being sent back. This results in the supply chain extending and so the carbon emissions increasing.

glass packaging

Glass is a always more sustainable than plastic

This is not always true. Glass containers are heavier to transport and are not always recycled back into glass products even after they are collected. They may end up being used in roads amongst other things. For example, I have seen food products presented in glass packaging which can then be recycled so is touted as a more sustainable option. BUT only if the consumer decides to recycle it.

Biodegradable means compostable

As we have discovered over the years, there are different meanings to the word “degradable”. If you see something labeled as “bio-degradable’ Yes it will degrade but many times not without some serious industrial processes. Otherwise they could be in the environment for many years. A label called oxo-degradable is common to see on some plastics. It means that the use of chemicals is required to break them down. This in turn creates microplastics which as we all know are a huge problem in the marine and terrestrial environment and can end up in our food chain. So, next time you are looking at “degradable” bag for example, check what kind of degradable it is.

All plastic is made of the same thing

There is no one type of plastic and yes, all of it is a pollutant. The challenge is to reduce your use of plastic and change the types that we are using. There is a large focus right now on creating plant-based materials for the plastic so producing a more sustainable option. Longer term options are being looked at which include larger scale utilization of these methods. “An example is Tetra-Rex. This is a plant-based carton made from paperboard and plastic derived from sugar cane” said Erik Lindroth from Tetra Pak. If you research some of the companies that are using this type of plastic packaging, you can focus your buying on these options.

Food without packaging is always better

Before this delightful pandemic came our way, there was a very large push around the world to start introducing food stuffs with no packaging. However, this can also have its draw backs. By wrapping in plastic, the shelf life of a food product can be extended so reducing the food waste. Food spoilage and waste can have an even bigger footprint than the single use film. I am not saying that single use film is great, no. It is a pollutant, but it is extremely important as well to take into account the food wastage that may otherwise occur. Food packaging is just a small part of the whole footprint of the product.

All aluminum is bad

After plastic, aluminum is very much frowned upon. Almost 75% of all aluminum is still in circulation which goes along with the thought process that it is infinitely recyclable. The problem has always been though, that it is very energy intensive to recycle to creating a large carbon footprint. However, there is a focus now on low energy aluminum which is produced using clean energy processes. So making the carbon footprint less. This is a great example of a sustainable future and a super weapon in the fight against climate change according to a UK former climate and energy minister.

I know it is hard to take from this one clear message. Yes, plastic is bad, but it it not always the worse option and can be recycled, in the right way and we need to try and prevent it from reaching the oceans. The best we can do in general is juts to overall consume less and be more mindful or what we are buying and how. Everything we can do will have an affect on our planet and oceans. That is what we are trying to save.
