That's undoubtly true. Agriculture allowed the population to grow to a level where it at last fails to nourish all and the higher population limit will apply. Despite of all the efforts to increase the yields like with chemical fertilizers, pesticides, hormones and so on. Would we have remained at a huntergatherer state, human population would be very low - like it was 15,000 years ago and before. Due to limits of available food and exposure to nature threats -climate -angry bears and so on. However again the difference is not between plant or animal agriculture. It's between agriculture or not. It's not an impact particularly plant agriculture has. If you consider the present cultures on earth, how they do agriculture and how they deteriorate the environment you can't tell that more plant based cultures have more impact than more animal based cultures. The ca. 600 mio inhabitants of US and EU shurely have a bigger impact on nature than the rest of the whole world together. India existed for hundreds of years (millenia even) at a level of several hundred million people but the environment was stable - the agriculture was a cycle. Our animal based western society exists (in industrial state) only for about 100 years, but the changes to nature already made are massive, long-term and some can never be redone. Most is from industry. Probably it isn't caused by difference in agricultulture (animals or not). Or is it? Cheers Amadeus S.
