What would happen if all trees disappeared?

What does a decaying tree look like?
These can be tough to spot, but they look like small dots along the ends of the branches (think of a connect-the-dots puzzle). If you don’t see those dots along the ends of the branches, the tree could be dead. Evergreen trees are a bit different. They typically stay green all year round and cycle their leaves out.
How long until all the trees are gone?
Alarming new research conducted by Dr Thomas Crowther at Yale University in Connecticut, USA, has predicted that if we continue our current rate of deforestation, the Earth will be completely barren of trees in just over 300 years.
How do you tell if a tree is alive or dead?
One of the best ways to determine if a tree or any plant is dead is the tree scratch test. Just beneath the dry, outer layer of bark in a tree’s trunk lies the cambium layer of bark. In a living tree, this is green; in a dead tree, it is brown and dry.
What happens if all forests disappear?
1 If forests disappear, the amount of carbon dioxide in air will increase, resulting in the increase of earth’s temperature. 2 In the absence of trees and plants, the animals will not get food and shelter. 3 In the absence of trees, the soil will not hold water, which will cause floods.
