Keeping this in consideration, what happens if we cut down too many trees?
If we would cut trees what is going to happen is that population won't stop growing but oxygen in the atmosphere will reduce. Another effect can be scarcity of food. They breathe in carbon dioxide and breathe out oxygen. We breathe out carbon dioxide and breathe in oxygen.
One may also ask, can we live without trees? Without trees there would be no paper, no pencils, even no coffee or tea, but more fundamentally there would also be no food for animals, or us, to eat. And since 70% of the Earth's land animals and plants live in forests, the majority would lose their habitat.
Hereof, what would happen if there were no trees?
Life could not exist on Earth without trees because they produce most of the oxygen that humans and wildlife breathe. Trees absorb carbon dioxide from the atmosphere and release oxygen using the process of photosynthesis. Forests act as giant air filters for the world.
What will happen when all the trees are gone?
Eighty per cent of land animals and plants live in forests and without the trees most of them will die. Trees also keep the ground wet and cool, and help to drive the water cycle. A large tree can push 150 tonnes of water into the atmosphere each year, which then falls back on the forest as rain.
