Phytoplankton produce more oxygen than all plant life on earth

💧ENVIRONMENT FACT💧 Did you know that 70% of all our oxygen comes from the ocean – mostly from a little thing called phytoplankton! Phytoplankton are tiny, photosynthetic organisms. This means they can manufacture their own food using energy from sunlight, producing oxygen as a by-product. They are often called tiny plants because of their ability to photosynthesize, but many species of phytoplankton are more closely related to protists and bacteria (not plants).⁠

Phytoplankton produce more oxygen than all plant life on earth and we need them for our atmosphere. Scientists are concerned that they may be greatly impacted by climate change.⁠
