We cannot put them back any easier than we can reverse climate change, but we can, and must, seek every possible solution to our current predicament.

Chemical fertilizers cause harm from their inception. Phosphate mining damages habitat, pollutes waterways, and creates a radioactive byproduct, phosphogypsum. Chemical fertilizers emit methane pollution into the atmosphere during production and after application. They also pollute waterways with excess nutrients in a process known as eutrophication. […]
