Di Martin: Australia is pricing things we've never tried to price before. We've heard about pricing carbon. But what about ecosystems, and even biodiversity itself?Biodiversity is the way all bugs, plants and animals coexist. It keeps nature healthy, which keeps people alive. Clean air to breathe, clean water to drink, healthy soil to grow food.
But with too much carbon in the air, too many water licences issued on the Murray-Darling, too much bush bulldozed, Australia's biodiversity is failing.
Our economy may fall over, but it's not just about the financial meltdown. Nature is seizing up, and it's costing big bucks. Putting a dollar value on nature might help, but how much is a bacterium in a lake really worth?
