There are many. Any analysis must address ocean acidification, water quality, land use, and air quality. Inevitably this must touch upon economics, food production, energy use and production, defense, education, transport, and behavior.
Unfortunately, this is not twenty percent of the list and is barely a start. Need I fail to mention population, public health, and safety?
But we do not rule this planet alone, and surely if we continue to believe so, probably will loose the whole ball of wax. There is habitat, all the plankton, insects, birds, fish, reptiles, mammal? And forest and tundra, desert and savanna, wetlands and rivers, jungles and prairie, wilderness and grasslands, coastal and mountain.
Problems are not in a deficit mode. So then we can ask, what, if any remedies are available? How large? Of what kind? How approachable or feasible? How long would they take? Is this realistic?
