Have waded in with a resounding "no," I'm going to catch myself and add the following: Biofuels would be ok, IF:

1. We do not depelete any more forests.

2. We use the food to feed the hungry FIRST.

3. We can ensure no additional environmental impact (if the corn/sugar cane will be grown anyway).

Take care of those three big gotchas, including a ban on using artificial fertilizer on biofuel crops, and I'll look the other way.

But I'd rather see the excess land returned to natural forestation, first.

Whoever says "perception is reality" is daft. It's merely an abstraction, and often not a very good one.
