another trait that’s being developped in the plants, for example, is making the plant immune to glyphosate, allowing the farmer to wastefully spray the herbicide on the field. It will kill all plants except for the desired crops.

That’s largely inaccurate and mostly just your biased opinions.

If you were as much of an expert as you imply, you’d know that glyphosate doesn’t kill “all plants.” And it’s anything but wasteful.
