Federal policy on biofuels goes from bad to worse under Trump

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:

How much each change to the atmosphere has warmed the world:

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
Field corn is edible for humans. It makes perfectly fine cornmeal, grits, hominy, etc. And of course it's processed into corn syrup, which is technically edible for humans.
It just doesn't have as much sugar as sweet corn does, so it doesn't taste good when eaten as a vegetable.
Sweet corn is primarily harvested at a young stage, so it's not just the variety of corn, but also the choices of how and when to harvest and process.
A lot of the edible varieties are different cultivars, generally categorized as flint corn or flour corn. Flint corns can be processed into grits and coarser cornmeal, while flour corns can be processed into corn starch and corn flour.
Field corn/dent corn is the majority of what American farmers grow, and is generally not intended for direct human consumption, unless heavily processed into bourbon and corn oil and corn syrup.
Even the stuff that is processed into ethanol (for whiskey to drink or for fuel or other industrial use) is still converted into animal feed and corn oil after the fermentable carbohydrates are extracted.
Certainly. But it's still edible. Dent corn, for instance, can be and is used for cornmeal, masa, tortillas, and so on. The industrial monoculture varieties of dent corn are optimized for animal feed, ethanol, or whatever, but nothing's stopping us from eating them (except, in theory, the ridiculous amount of herbicide and pesticide that gets dumped on them).
The reason why we're growing so much corn that's not intended for direct human consumption is because of a whole shitload of broken incentives and megacorporation subsidies and America's meat addiction and the nagging worry that if we don't keep the land in use we can't justify stealing it from the natives however many generations ago.
Which is part of what the article goes into.
And it's why the idea that ethanol opposes Big Oil is so ridiculous. Ethanol and Big Oil go hand in hand. Their interests are aligned and Trump loves them both.
TIL. For some reason I thought those were all made from other kinds of corn.
