Today, our industries abuse our planet's resources for the short term benefit of all of us. Abolishing landfills is a confirmation that we are past such a myopic technological level. We no longer need them.

Growing up in the suburbs, I understand this quite well. But this land is not ours just because it is there and unused. We need to return a majority of the earth back to the ecology. Monkeys are falling out of trees in Mexico, 50% of bugs and birds are dead due to the ecocide, I could go on.
Just referencing 'unused land' as if it is ours to use by default is a gross misunderstanding and human-centric approach to ecology. There is more than us here.
