Summary:
- The oceans are home to a tiny life form called Prochlorococcus, which is the most abundant photosynthetic organism on Earth. It produces about 20% of the world's oxygen.
- Scientists have found that Prochlorococcus is highly sensitive to warming ocean temperatures and may not be able to survive the effects of climate change and global warming.
- As Prochlorococcus declines, it could have a significant impact on the entire marine ecosystem and the global oxygen supply, highlighting the importance of addressing climate change to protect even the smallest life forms in the oceans.
