MadSci Network: General Biology |
Hi Marc, There are many points that could be raised here, but I'll keep the answer short. You are right that we need plants as they use up carbon dioxide and produce oxygen. Animals, including humans, use oxygen and produce carbon dioxide, so being the only human would not stop you being able to breathe. Assuming you were in a place where you could find food, water and shelter there is no physical reason why you could not survive, although it would be a very lonely experience! Yours, Dr David Hubble, Eastleigh, Hampshire
