To substantiate your point, I was thinking about deforestation for farming in Indiana (where I live) and Ohio last week and learned that Indiana was 90% forest until taxes got in the way. It's crazy that something as silly as taxes can cause most of your forests to become farmland.
Yeah, it's crazy to insentivise deforestation. But people need to eat. And, depending on who you listen to, there is even some evidence that the rainforest may have been a cultivated environment itself, in the dim and distant past.
Someone around here did clear the forests for farmland... and people are doing ok.
Its not that everyone died, as the comment I responded to said.
