There is a large difference between extracting fossil fuels from the ground and using substances extracted from plants. Only one of them is renewable, and hence the only sustainable way for the human species to live.

Irrelevant for spoon making, too few of those ;)
Yes but it is important not to confuse the source with the form.
For example we can create hydrocarbons using solar/wind energy and that is still "renewable" even though hydrocarbons are involved. They are merely the medium of energy storage.
