Working on planting more trees is nice, but we have a much bigger problem.

Phytoplankton are responsible for between 50 and 80% of the oxygen in the atmosphere https://oceanservice.noaa.gov/facts/ocean-oxygen.html

Phytoplankton population has declines almost 40% since the 50's. https://www.scientificamerican.com/article/phytoplankton-pop...

As the oceans warm and more fresh water is released into the ocean from melting ice it caused the ocean to become more acidic, which is causing the phytoplankton population to decline further. Also as the water warms different types of phytoplankton increase and not all as economics at converting CO2 into oxygen, and some create other problems.

Phytoplankton are the basis for the marine food chain

Over 3 Billion people rely on the oceans as their main source of protein.

There is nothing we can do as a "stop gap" solution for the oceans, and phytoplankton, just like any natural system in decline the phytoplankton population will continue a slow decrease and then when it hits a tipping point it will crash.

When the phytoplankton population crashes, and it will, the impact will be catastrophic. Short of inventing a technology to capture and sequester 45 Billion metric tonnes of greenhouse gases from the atmosphere each and every year, there is nothing we can do to stop or even slow down what's happening to the oceans.



Is there anything we can do?


There are some schemes to increase ocean productivity, by increasing the amount of limiting nutrients.
