Hi everyone, Today we're learning about phytoplankton. Phytoplankton are microscopic organisms that live in both salt and fresh water, and are mostly single-celled plants. The name phytoplankton comes from Greek and means 'drifting/wandering plants'. One of the most well-known phytoplankton species is green algae. Photosynthesis and carbon transport Phytoplankton contains chlorophyll and photosynthesises . This process absorbs carbon dioxide and creates oxygen, which is released into the surroundings. This is so effective that according to a NASA page : "Through photosynthesis, phytoplankton consume carbon dioxide on a scale equivalent to forests and other land plants." Phytoplankton is accountable for the majority of the carbon dioxide that is transferred from the atmosphere to the ocean. This carbon is carried to other ocean layers when the phytoplankton dies and sinks to the ocean floor or is eaten by animals, that then gener...

Hi Everyone! Welcome back to Green World, where today I wanted to talk about why people didn't act sooner about the climate crisis , when we have known about this issue for decades. I asked myself this too, and it wasn't until I read the chapter about it in Greta Thunberg's book that I started to understand the reasons behind why action was not taken sooner, and why this crisis has been allowed to escalate as far as it has. As someone who has only been on the planet for 14 years, a part of me does resent people around long before I was for not having acted on an issue that they knew would continue to affect people around the world. They knew it was not an issue that would go away, so why didn't they act, when it was easier to do so? Changing our now very ingrained habits is so difficult, whereas fifty years ago, ways of life could have been more easily influenced. Well, there are a few reasons why action was not taken to combat cl...

Hi Everyone! You may be aware that Wednesday was International Women's Day, so today I wanted to share a book review for a book written by one of the most inspiring women of our generation: Greta Thunberg. She is, of course, the legendary creator of the Fridays For Future movement and has inspired thousands of children to skip school on Fridays to protest for the climate. She recently compiled a book, simply entitled: The Climate Book. Here are my thoughts. This is a compilation of articles and essays from the best climate scientists, activists and high-profile people, which makes up, in my opinion, the climate bible . It quite literally encompasses everything you may want to know about the climate crisis, from the science, to how it affects us, what we've done and have yet to do, and so much more. This book is everything. I have not yet read the whole thing, because let me tell you, this book is HUGE. It's also of course very den...
