If you have to farm your food instead of getting it from nature because your species has populated so much, you’re over populated. Not to mention, all the animals and land this would kill. Things like this can only ever be temporary if they’re going to be used, instead of left to do what is needed. In a few years if they keep harvesting it will start to deteriorate, not to mention that with all the chemicals pumped in to all that, and the animal agriculture that has gone into it, the project probably destroyed more land in Africa and the Middle East than they “re-greened”, which only makes humans more overpopulated. There’s a whole chain of events everyone seems to be leaving out because it’s not directly tied to the project, even though the effects on the earth, the non-human animals, and the human animals are happening because of it.

Just because humans have the might to use the Earth, and kill off all other animals and flora, does not mean we should.
