ELI5: Ocean phytoplankton and algae produce 70-80% of the earths atmospheric oxygen. Why is tree conservation for oxygen so popular over ocean conservation then?

Trees are more familiar, and humanity’s effects on them are more easily understood. You can imagine 100 acres of rainforest being cleared for ranch land or banana plantations a lot more easily than a cloud of phytoplankton dying off. Just the simple fact that trees and humans are on land, while plankton and algae are in water, makes us care about them more.

Also, the focus on tree conservation does far more than just produce oxygen. In fact, I’d say that’s pretty far down the list. Carbon sequestration, soil health, and biological diversity are all greatly affected by deforestation.
