I think trees are good most of the time.Even when they are burned down, life grows from their ashes(what beautiful phrase,I think I'm going to cry
).
Young trees helps to put some oxygen into the environment and consumes a lot of carbon dioxide;and grown up trees are very balanced(consumes as much oxygen as they "spit out",at least most of them). I don't think trees could contribute significantly to global warming or anything harmful to other live beings nowadays.
But everything is possible,I don't think those articles really prove trees are a bad thing,they didn't make tests to really prove it with numbers.Even if they are,in a short period they can be useful untill we reduce our CO2 emissions.If you have some other links I would like to take a look.
