You've heard of the rest: sea-level rise, eutrophication, melting of the polar ice caps, expansion of oxygen minimum zones, pollution, loss of biodiversity, overfishing.

For example, it found that “ammonia emissions, nitrogen leaching, and nitrous oxide emissions per product unit were higher from organic systems,” as were “land use, eutrophication potential, and acidification potential per product unit.”

According to a recent British meta-analysis, ammonia emissions, nitrogen leaching, and nitrous-oxide emissions per unit of output were higher in organic systems than in conventional agriculture, as were land use and the potential for eutrophication – adverse ecosystem responses to the addition of fertilizers and wastes – and acidification.

Poor waste management allowed the capital city of Harare’s main water source, Lake Chivero, to become heavily polluted from sewage effluent, causing eutrophication (when nutrient buildup causes excessive vegetation growth).
