We have to create a sustainable environment, worldwide, and we're not doing it. The best thing we can do with the rest of this century is aggressively acquire - and put aside - the richest natural reserves that we can, and then do our best to manage the needs and desires of the 11 billion people we expect to have by the end of the century. This is where biology is headed. For that reason, the sooner we get on with mapping biodiversity on Earth, the better off biology will be - not to mention the whole subject of saving it before we carelessly throw it away.
