Why is deforestation an issue for the climate?

Answers

Answer:

They are bad because they cause global warming.

Explanation:

When trees are cut, burned down, or are allowed to rot they release carbon dioxide. As you probably know carbon dioxide is very bad and can cause global warming.

Deforestation is an issue for the climate because the trees contain oxygen and we get most of our oxygen from them. If we have less and less trees that means less and less oxygen. We need oxygen to breathe. Deforestation will take that from us.




Basically , the carbon dioxide leading up to our fresh air is toxic gas and we don’t need to be breathing all that in. It’s not good for our long or long-term in general.

Hope this helps!
