There is a paper that appeared in January in Science: Planetary boundaries: Guiding human development on a changing planet.

The Planetary Boundaries framework proposes quantitative limits for human perturbation of critical Earth system processes, and a «safe operating space» within which human activity should attempt to stay in order to avert the risk of large - scale, possibly abrupt or irreversible environmental change.

Dr Lenton (who is also one of the creators of the planetary - boundaries concept) and Dr Watson suggest that energy might be used to change the hydrologic cycle with massive desalination equipment, or to speed up the carbon cycle by drawing down atmospheric carbon dioxide, or to drive new recycling systems devoted to tin and copper and the many other metals as vital to industrial life as carbon and nitrogen are to living tissue.

(05/20/2013) Human - caused changes to our biosphere — the global total of the world's ecosystems — are now so great and alarmingly rapid that human lives and societies undoubtedly face epic challenges in the near future as our biosphere deteriorates, planetary boundaries are reached, and tipping points exceeded.

The failure to account for different environments points to the main problem with the planetary boundaries framework: it only measures environmental change as negative — as progression toward supposed biophysical boundaries — and never as positive, either for humans (e.g., more food) or environments (e.g., higher yields resulting in less deforestation).

The planetary boundaries hypothesis, first introduced by a group of leading earth scientists in a 2009 article in Nature, posits that there are nine global, biophysical limits to human welfare: climate change, ocean acidification, the ozone layer, nitrogen and phosphate levels, land use change (the conversion of wilderness to human landscapes like farmland or cities), biodiversity loss, chemical pollutants, and particulate pollution in the atmosphere.
