> two quotes don't follow They do. A significant influence on those increases was thanks to fertilizers, insecticides, and herbicides. This goes hand in hand with water pollution and biodiversity loss, exemplified by dead zones in oceans and an 80% decline in insect populations in the last few decades. Improvements in irrigation systems have led to the depletion of our aquifers, which were filled over many millennia, and their renewal may take centuries. Mechanization and soil management lead to soil erosion; maybe only a few decades of soil remain until we lose all of it. Less than 50% of our crops are for human consumption; the rest is used as animal feed and biofuels.
