I'm curious how old you are, MSH, if you don't mind my asking. I don't think it will explain the weird apocalyptic bend or anything, just curious if it's a young guy who's passionate about this, or an old man ranting or what.
I mean, you take things which could sound reasonable, but then go a few extra steps into "YOU MANIACS, DAMN YOU, DAMN YOU ALL TO HELL!" territory.
I mean, you're talking about setting up monocultures and monocrops, the US has about 1.4 million km
2 of arable land in use, with tons of different crops across it all.
It
also has around 130,000 km
2 of land devoted to a specific type of crop.
See if you can guess which one, corn maybe, wheat, ooh, tobacco might be it!
Got your guess in mind?
It's grass, our lawns, bluegrasses, zoysias, bentgrass, bermuda, st. augustine, they're all present in various amounts, given water, fertilizer, regular mowing, manual weeding, pesticide, and of course... donations from dogs.
Indeed, they're actually helpful in reducing the urban heat island effect, and draw down a good amount of carbon dioxide, anywhere from 12~35 Gigatonnes of CO2 per year conservatively and wipe out the 1 or 2 Gigatonnes of CO2 we exhale along with most or all the ~33+ Gigatonnes of CO2 we emit. They also take a fuckton of water, lots of which winds up as runoff.
So hey, there are things to get mad about, really the whole "let's use ethanol to reduce CO2 emissions" turning into "LET'S GROW ALL THE CORN FOR ETHANOL" is kinda crazy, and naturally monocropping is a problem, just not sure if it's quite in the "goddamn it fuck it all you stupid bastards deserve to die" sort of territory you make it sound like.
