Ok was able to read (thanks scarmig). Their claim is that we alter approximately 2.27 acres worth of environment to support each person (mainly nutrients). This comes out to 40%?? of the land of Earth being transformed and showing state change. Through this transformation of land and our consumption of primary nutrients we currently consume between 20-40% of the biota production and also degrade the whole production chain. Their claim is that at current human growth levels we will exceed 50% transformation of the land mass and this will cause rapid, unpredictable changes (state change) and we will reach this in 2025. Interestingly, they claim that through greenhouse gas emissions we have delayed this massive state change (by putting more energy into the environment).
