The United States agricultural system has the resources knowledge and desire to meet the ever growing global demand for food. The day has come that people and groups who get in the way should be labeled as anti-human. The constant rejection of proven safe technology is the greatest challenge we face.
Putting this into light is the recent report by Abstract Potsdam Institute
In our globalizing world, the geographical locations of food production and consumption are becomingincreasingly disconnected, which increases reliance on external resources and their trade. We quantiﬁed to what extent water and land constraints limit countries' capacities, at present and by 2050, to produce on their own territory the crop products that they currently import from other countries. Scenarios of increased crop productivity and water use, cropland expansion (excluding areas prioritized for other uses) and population change are accounted for.
We found that currently 16% of the world population use the opportunities of international trade to
cover their demand for agricultural products. Population change may strongly increase the number of people depending on ex situ land and water resources up to about 5.2 billion (51% of world population) in the SRES A2 scenario. International trade will thus have to intensify if population growth is not accompanied by dietary change towards less resource-intensive products, by cropland expansion, or by productivity improvements, mainly in Africa and the Middle East.
Up to 1.3 billion people may be at risk of food insecurity in 2050 in present low-income economies (mainly in Africa), if their economic development does not allow them to afford productivity increases, cropland expansion and/or imports from other countries.
