Though I'm not supporting oil companies, this is very wrong. Without oil (or vehicles in general), the manpower required to produce same amount of food will increase multiple times, and food won't travel much from the place where it grows, limiting the distance that people can reside.

So yes it's a necessity but as other have said, oil companies can keep operating without lying about climate effect though they'll get less profit as impact.

There were tens of millions of bison freely roaming America before we absolutely purposefully decimated them all. They existed "without oil". Grazing, pooping, making some of the most fertile soil in the entire world.

Maybe if we had built a society around respecting, honoring, and preserving an incredible evolutionary product we'd be just fine.

We wouldn't. This is a straight up math calculation. If we dedicated all arable land in the entire world to optimal food production using traditional agricultural techniques (the stuff which doesn't involve fossil fuel products), we'd only be able to generate less than 1000 calories per person. The world would starve.

Respect and honor doesn't magic food into existence.
