Oceans hold 90% of worlds biomass
A very interesting topic on the Kim Hill radio program interviewing Chris Bowler, marine biologist for the Tara Oceans Science of France.
Two things he mentioned that struck me, the first of which was that the oceans hold 90% to 95% of all biomass on the planet. While I knew that phytoplankton provided 50% of the oxygen I had no idea that marine life made up such a huge proportion of life and was so important to the planet.
The second was that most of this marine life is within the top one hundred metres, where sunlight penetrates, and when you consider that the ocean is ten kilometres deep this represents a very thin membrane across the surface.
I have always believed that the big action with climate change was in the oceans but I was not aware that this applied to life on Earth as well. We need to know more about what is happening there and look after it as our lives depend on it.
