The best answer I've heard is that the food chain would collapse. How long can you go without eating? We would be a rather grouchy planet in a few days and would be likely to die from food wars (that would be the primary affect on humans as opposed to other animals). Many suggest running out of oxygen but the atmosphere is huge (About 80% of the total mass of the atmosphere is contained in the first 6-7 miles over the surface of the earth) and contains 20% oxygen. Animals primarily inhabit the surface of land (plus a good bit of ocean creatures) so they are not likely to be able to consume all the oxygen before starving. I don't think there is enough biomass to account for the excess oxygen but somebody could crunch the numbers to be sure. Some suggest the decaying matter would consume the oxygen but the wood mass (trees and wood structures) across the earth contain millions of tons of carbon and would take years to rot - we would starve well before that.
