I grew up around hunting and farms and also don't find it surprising that animals are fairly intelligent.
While your statement about pasturing being good for the environment is partially true in that there are some forms that do some good, by and large meat production is actually one of the largest causes of GHG emissions.[1] A lot of this land would actually be used more efficiently for production of non-animal proteins like legumes, especially considering the land that is used to supplement pasturing through production of animal feed in most modern agriculture.
