The greatest mistake humanity has ever made

Although I do think there are inherent flaws to the agricultural system that we have created, I think that it would be impossible to support the population we now have with any other system for finding or creating nutrients. If our population was going to grow, it seems that agriculture was a necessity. Perhaps the root of the problem is, in fact, overpopulation.
I also think that agriculture is not going to immediately kill us off as the passage seems to suggest. Perhaps we will slowly experience less nutritional intake due to genetically modified crops or depreciated diversity in the things we eat, but it will not be a sudden, deadly change. I also think it is a little over the top to allocate the development of sexism and classism to the creation of agriculture. It seems that these trends and traits would have occurred even without the creation of agriculture. I think that agriculture has to be at least a part of the solution to how we live our lives, but it must be altered and amended in order to be sustainable.
