This also ignores a dire problem humanity has created for itself: massive amounts of arable land wasted on fuel crops rather than food for people.

It's similar to the farming industry producing incredible amounts of food just to feed cattle rather than to feed people. Not all crops grow on all land, of course, but as long as there are large scale famines in the world, I think it's immoral to dedicate so much land towards inedible foodstuffs.

We're already burning forests under the guise of "renewable fuels" that assume we've assured that the forests are allowed grow back the next 100 years even when biofuels are no longer profitable.

There are good reasons to rid ourselves from fossil fuels where we can, not just because of global warming but also because of political reasons (the oil states getting away with literal murder and a blind eye being turned towards their funding of what would become 9/11, for one). However, I fear that these plant based "alternatives" will be quickly bought up by the oil industry, touted as the future of green energy, and used to postpone greener alternatives to the internal combustion engine yet another decade.
