Beyond Boundaries

Scientists have identified 9 areas that are crucial for the assessment of life on planet Earth as we know it. Exceeding their boundaries means a serious threat to the natural world and resources. They are:

-Fresh water use
-Change in land use
-Rate of Biodiversity loss
-Climate change
-Nitrogen cycle
-Phosporus cycle
-Stratospheric ozone depletion
-Atmospheric Aerosol loading
-Chemical polution
-Ocean acidification
Now, the graph shows that humans have overstepped 3 of the 9 planetary boundaries and are close to transgressing others. The ultimate impact: unknown. The way of limitation: unknown. Wow, what a prospect. (from New Scientist 2010)
