CHEMISTRY IS EVERYWHERE

Nature:Microorganisms shuttle chemicals(to provide nutrients for plants)

Plants photoysnthesize(convert simple molecules into their food source)

Release Oxygen

Animals and humansare hosts to countless microorganisms

Ecosystem Chemical Connectivity ?

Shifting Baselines

What people expect as “normal” on our planet has changed over time;

especially with regard to ecosystems

2005 figures

Box 00.04

In 2009 the world population is estimated to be 6.8 Bn people

Biologically productive area in the world 11 Bn hectares

11 Bn hectares per planet

Remember, average “ecological foot-print” in USA 9.7 hectares per personWhat if the average “ecological foot-print” for the whole world was9.7 hectares per person

That would require a biologically productive area of66 Bn hectares

For everyone in the world to have the same life style as the average US citizen, a total (biologically productive) area of 66 Bn hectares is needed.

But the planet only has a total biologically productive area of 11 Bn hectares.

Therefore, 6 planets are needed!
