Climate 101: Deforestation Questions
AleksandrR [38]

1. I can’t think of the percentage off the top of my head, but I have the rest of the answers:

2. By cutting down trees, you are releasing the carbon dioxide that the trees were previously storing, and deforestation also limits the amount of trees available to take part in photosynthesis.

3. In order to have agriculture, you must have land to grow the food on; in order to get this land, some people need to burn jungles and rainforests for more space (what‘s currently happening in the Amazon).

4.  Set incentives for the government. This encourages them to not chop down trees, as there will be a visible benefit.

5. I would say education. It’s difficult in less developed countries, because it truly is all that they rely on; but through education, people can at least be aware of what they are doing so when the time comes they will be able to stop it.
