Completely untrue. Everyone and their mother seems to think that the only way to get these fuels is to farm, produce, and transport them. Completely false. 60% of human waste can be converted. Something that we are already making long before alternatives came along. From old candy, human feces, cooking oils, thrown away furniture, and even plastic. 60%-80% of landfills can be converted. Think of it as a byproduct to human living. We're going to create it regardless so we might as well convert it. They already do it in Japan at some places and in the US, Texas and Tennessee. We just need to implement it on a larger scale. Plug the plant into a nuclear reactor and we've got a clean solution.

When we finally start using up all our own waste we can then start going out into the "Great Pacific Garbage Patch" and get all we need from there.
