What is the value of Nature?

Mark Tercek, the CEO of The Nature Conservancy, spoke at the Westminster Town Hall Forum this past week.  He's written a book "Nature's Fortune: How Business and Society Thrive by Investing in Nature." He suggested we consider nature as "green infrastructure".  This will allow the environmental movement to:
1. Broadens support to include more constituents
2. Lead to more financial resources for the movement, harnessing support from capitalism
3. It changes the dialogue into problem solving

Nature also has intrinsic value, beyond the price tag a capitalist might place on it for their financial benefit.  As something of an idealist I think it seems rather sad that the only way for our natural environment to get the respect it deserves is through commodification.
