Okay - so I'll start off by saying that this question is for research, and any information you may have, whether it be a book to look into, and article to read, a person to try and contact, or just your personal opinion would be VERY helpful.
Well... what WOULD happen if all plants died? If something changed and you woke up the next day and EVERY single plant on Earth was dead... I know that plants produce oxygen for humans and animals, but does it produce the ONLY means of oxygen?? How long would it take before breathable air was gone? A day? A month? A year? Would everyone end up suffocating?
I also know that high outputs of carbon dioxide is the "cause" for "global warming". Would this sudden burst of the gas, unable to be filtered by plants, cause a faster destructive and catastrophic climate change? How quickly would things change with such a newely and unexpected carbon dioxide output? Would that end up destroying us before oxygen ran out???
Please tell me what you know, you've read, or just think. Any comments would be helpful! Thanks!!!
