If the world turns to intensive farming in the tropics to meet food demand, it will require vast amounts of phosphorus fertilizer produced from Earth’s finite, irreplaceable phosphate rock deposits, a new analysis shows.
Studies of how climate change might affect agriculture generally look only at crop yields. But climate change may also influence how much land people choose to farm and the number of crops they plant each growing season. A new study takes all of these variables into account, and suggests researchers may be underestimating the total effect of climate change on the world’s food supply.
Brown University epidemiologist Joseph Braun has shown that prenatal exposure to PFAS chemicals is associated with greater adiposity in children.
