Land size to feed your family (pic)

I can only imagine how quickly 1/10 acre would become infertile when used for farming

This also shows a lack of knowledge. When properly rotating crops, land can be used indefinitely. Remember everything is a cycle. While it may be true that planting corn in the same field year after year without fertalizing will deplete the soil, simply rotating the types of crops grown will replenish the soil.

Actually the planet can support approx. 4-5 Billion people and be sustainable...so...thenodnarb, we only need to get rid of 2-3 billion people not 6.5.

then I guess we should all be dead by now

Actually, the planet could probably support close to a 50 billion people -- maybe 100 billion. You might not like that world but I think it could be done.
