What do Oceans have to do with climate? When thinking about climate change, the first things that come to mind are probably not marine environments, but rather gas emissions, polluting industries, or mass-consumption. In fact, however, they are all connected.
OCEAN’S ABILITY TO FIGHT CLIMATE CHANGE
For starters, about half of the anthropogenic carbon dioxide (in other words the carbon dioxide that we emit through transport, industries, energy, etc.) is absorbed by the Oceans. Thus, Ocean health plays a crucial role in climate change mitigation. Unfortunately, things are not currently looking bright. Due to climate change and overfishing, the ecosystems of the Oceans - and the important role they play to regulate our climate - are in severe danger.
OVERFISHING - A PART OF THE NEGATIVE PATTERN
Overfishing harms our climate on many levels, both through its harmful effects on Ocean’s capacity to regulate the climate, but also through its direct emission of greenhouse gases. These days, there is a lot of focus on microplastics, but overfishing is in fact considered the main environmental threat to our oceans. It's important to remember that fishing vessels are run on heavy fuels, which besides carbon dioxide, also emit black carbon, sulfur dioxide, and nitric oxides. In the Arctic, fishing vessels are the largest cause of greenhouse gas emissions.
Fish oil, commonly used for omega-3 supplements, is the most valuable product of so-called “reduction fisheries” (where the catch is processed to bulk feed, rather than food for humans). Omega-3s are essential to our health, but our demand for them is not only contributing to overfishing, but also climate change. Ironically, the actual source of these omega-3s in nature are not fish, but algae - the tiny little microalgae that convert carbon dioxide to oxygen (and omega-3) by photosynthesis, just like land-based plants. These microalgae - also called phytoplankton - are the main consumers of carbon dioxide in the Oceans, and thus play one of the most important roles on our planet in terms of regulating our climate.
MICROALGAE, OCEAN'S LITTLE SUPERHEROES
Whilst microalgae help with reducing carbon dioxide in the Oceans, the fish-oil industry contributes to adding even more CO2. Isn't that a good enough reason to go with algae instead of fish? By choosing your omegas directly from algae instead of fish, you do not contribute to overfishing, additional gas emissions, and in the end climate change. It's better for the fish, it's better for Oceans, it's better for the Earth.
Talk about a win-win.
