From the link that you provided:
Habitat destruction is currently ranked as the primary cause of species extinction worldwide. It is a process of natural environmental change that may be caused by habitat fragmentation, geological processes, climate change or by human activities such as the introduction of invasive species, ecosystem nutrient depletion, and other human activities.
Emphasis added by me. I am trying to explain that the current, sudden
species die-offs are being caused largely (not entirely, largely) by warming. Land clearing has been going on for centuries and the losses due to that can at least be predicted fairly well. Warming habitats are a relatively new phenomenon that isn't explained by the clearing of land. Amphibians aren't vanishing with extreme rapidity because people decided to drain all of the marshes a few years ago. Do you really believe that insect populations are crashing because our decades-long use of pesticides has suddenly started to kill vastly more of them, even in places where pesticides aren't used? But hey, think whatever you want - people always do. I just got attacked recently in another forum because I suggested that part of sustainability was reducing the number of children we produce. This tendency to blame only
things over which we personally have no control, while dismissing our own contributions, is why this extremely belated effort to do something positive about AGW is going to fail, and fail miserably.
I've been thinking about this, lately, in the context of the apparent dearth of detectable civilizations in the galaxy. I wonder if almost all species that are able to advance technologically are doomed to extinction by the same instincts that allowed them to dominate their planets. I'm picturing tens of thousands of dead or barely living planets, littered with plastic and abandoned personal vehicles...
