Using grasslands for grazing is one of the prime destructive forces in riparian areas. You end up with less diversity than you began with. Cropland tends to have less diversity because the only animal or insect visitors to it are those that can benefit from the presence of the crop or the presence of some other creature that depends on that crop. Employing pesticides and herbicides and fungicides erodes the viability of the cropland even further making it necessary for periodic supplementation. Vegans have a moral issue with consuming anything that they think may be capable of being opposed to their consumption. From parent: >Most vegans, including me, are vegan because we find the exploitation of animals morally unjustifiable. Our world includes the nonhuman world. And by being vegan we are saving it. I guess it's okay to fail to consider that there is a portion of the nonhuman world that might not want to be exploited. Hard to justify that you are saving that portion of it by cultivating it so you can eat it. I wonder when we'll see the disclaimer in the movie credits that no plants were harmed in the making of the movie.
