I've recently spent some time moving around the rural areas around my city and been really bothered by just how flat agriculture has made so much of the land. Sure there are preserved parks and even areas with some form of forest mingled with residential properties. But the sheer amount of "flattening" and deforestation I "saw" (as it is easy to not notice it if you consider agricultural land normal) built up to a really unpalatable and disturbing feeling. It was the first time I felt like I had some rational belief that the human population really should be reduced. Without some wonderful energy source that can provide a worthwhile substitute for sunlight, food production is necessarily limited to the top 0.2-1.5m of land (right?). From aesthetic to environmental factors, it really seems like an awful thing to reduce so much of the fertile lands to just that.
