Why trees should not be cut?

Some trees can be cut down as long as there’s not more taken out of a forest than can grow back. If forests are completely cut down, the ground is no longer protected so it can be damaged by erosion making it harder for new trees to grow again.

Can trees survive without humans?

FILTHY AIR: Without trees, humans would not be able survive because the air would be unsuitable for breathing. If anything, people would have to develop gas masks that filter the little oxygen that would be left in the air. … Anyway, trees take carbon from the atmosphere through photosynthesis in order to make energy.

What would you not see if all the trees went extinct?

Without trees, formerly forested areas would become drier and more prone to extreme droughts. When rain did come, flooding would be disastrous. Massive erosion would impact oceans, smothering coral reefs and other marine habitats.
