@alexs.5871 Society can change, but we still have to abide the nature for our sustenance. It's not a choice, but necessity.
When you farm a land, you use up the nutrients in the soil. There's only three ways to continue farming.
1) Leave the patch to forest (takes 80 years), and burn new forest to ground for new field. (VERY bad for environment)
2) Rotate edibles and grasses to let the fields rest, and use mined, factory produced industrial fertilizers to revitalize the growth. (Also bad, and need at least 30 % more farmland to account for resting furrows, than our current agriculture)
3) Previous,, but use otherwise useless grassfields for animal fodder, and fertilize with tbeir waste which greatly reduces, the need for industrial fertilizers destructive to environment.
As a side extra, animal waste can, and is, also used to produce biofuels, before used as fertilizer.
PS wild pigs are almost as destructive to environment as 17th century humans, and cows or sheep can't even survive in nature, but will die suffering and wholly disappear without being cared.
