Document Summary
Es is the earth systems, pb is the planetary boundary. The anthropocene is the new epoch that has been proposed. Gave us the environment that allowed us to farm.

Earth syste(cid:373)"s a(cid:271)ility to defe(cid:374)d itself fro(cid:373) environmental shocks: the anthropogenic perturbation levels of the es processes that exceed the proposed pb are: genetic diversity, biochemical flows, land-system change, and climate change. Genetic diversity: top predators have almost become extinct, habitats are disappearing, prey are disappearing; genetic diversity is reduced when you are using biogenetic engineering processes. *a place in norway has a huge vault filled with seeds trying to maintain genetic diversity: anthropogenic is originating in human activity, calculating pb is essentially a risk analysis. We know how far we can push before the tipping point.
