Our planet series: oceans and seas


This autumn, I wanted to start a series of blog posts talking about our planet, how climate change effects it, and what we can do to help.

This week we start with oceans and seas.

Did you know that they cover three quarters of our planet? These three quarters regulate global temperatures, provide us with food and 70% of the oxygen that we breathe. However, at the moment they are in danger. Here are the main problems that oceans and seas face: 

Melting of ice. You probably have heard that the amount of ice on the planet is decreasing every year, and the temperatures are rising. So, what does it mean? Increased levels of carbon dioxide [direct result of fossil fuel burning] make the water more acidic, leading to destruction of marine ecosystems, including coral bleaching.

Plastic plague. Unfortunately, since the creation of first single-use plastic bag in 1965, we have dumped so much plastic in the oceans that, according to Monterey Bay Aquarium in California, 100 000 sea animals die from being caught in plastic, or eating it. These days microplastic can also be found in seafood we eat, and sea salt.

Overfishing. Recently I have learned a shocking fact: overfishing in Mediterranean sea has reached 96%. What is overfishing? It is simply catching more fish than could be reproduced naturally. The problem is also the fact that many seabirds, sharks, whales, and dolphins are becoming victims of by-catch. Decades of illegal fishing and unsustainable fishing practices have also led to disappearance of 90% of large predatory fish. Imagine, we only have 10% left. Our consumption habits seem greedy, don't they?

It always seems like these things are far away, "not my problem" kind of issue. However, climate change is real, and with the rate the problems are escalating, they soon might become even more real than it feels at the moment.

So, what you could do to change it?

Consume less/no plastic: try to minimise it when grocery shopping.

Eat less fish: reducing the demand will decrease the need for fishing. Think who you buy from: support brands/suppliers that only use sustainable fishing practices.

Eat less big fish: as I mentioned above, 90% of those are already gone, let's try to save the rest.

Spread the word: awareness and education is always a key to more sustainable future.

Vote: vote for people who support sustainability policies and laws. Remember, vote is a privilege, we did not always have this right, use it.

As always, if you have any question, just leave them in the comments, or feel free to email me ✨
