We face numerous other threats as well: the spread of toxic synthetic chemicals worldwide, vast epidemics, and a dramatic decline in the quality and accessibility of mineral resources, water, and soils.

 

Resource wars are already with us; if a “small” nuclear resource war erupted between, say, India and Pakistan, we now know that the war alone would likely end civilization.
