The oceans absorb nearly 1/3 of our carbon emissions; they are literally the world's lungs. How does the sea 'breathe', and why does it do it?
Our oceans absorb nearly a third of the world’s carbon emissions, a ‘breathing’ process that produces much of the oxygen we take in on a daily basis. As carbon levels increase so too do the acidity levels of our oceans, a process known as Ocean Acidification and one that damages our marine life.
In this Garden talk, Dr. Veronique Oldham takes us on a deep dive into the inner workings of our oceans, revealing the fascinating story of how some people dumped iron in the ocean to encourage the growth of carbon-munching marine phytoplankton - and ended up with nothing more than dead zones full of algae.
