Apart from the obvious increase in vacant land, we observe that the size of structures, in general, has increased over time. We have ended up building bigger and bigger structures that have a tendency to make one walking through it or standing beside it insignificant. Of course, many of these structures are visual manifestations of institutions and organisations I just described. What this tells me is that we value the lives of careless institutions and organisations over the lives of the humans, plants, animals and nature that guarantee their existence.
Such scales are seen in landfills, too. Here are some pictures and numbers about some of the largest landfills in the nation (you can read the articles here and here).
What I think is necessary to address when talking about issues of our impact on the environment is a look at scale. It is absolutely not possible to tread lightly with big things. Big tractors compact soil, oxen do not. Big power plants require massive amounts of fossil fuels, while living with less energy wouldn't necessitate the rape of mountains. Big buildings take a lot to erect, while smaller ones recognise our place in the world and the grander scheme of things.
