There is a difference in long-term climate change and short-term weather variability.
If all the forests are logged the carbon dioxide stays in the air and the living organisms can`t survive. If there is too much carbon dioxide in the air then there is no life in the World. Trees can make oxygen out of carbon dioxide so they can save us. Expecially rain forest are good for fighting against climate change. Human needs to protect our forests becouse the forest can`t protect itself.
