What many of us fail to appreciate is that our disregard for the well-being of biodiversity, is as grave a threat to humans as climate change is, because it is healthy, productive ecosystems, not Best Buy or Costco, that support us, and it is biodiversity that makes ecosystems healthy and productive. To put it bluntly, we are destroying the natural world that we cannot live without.
