In addition to its effects on climate, the expansion of agriculture has caused massive losses in biodiversity around the world: natural habitats have been converted to farms and pastures, pesticides and fertilizers have polluted the environment, and soils have been degraded.
Why is agriculture bad for biodiversity?
of farmland use
Livestock farming is a major source of surplus nitrogen and phosphorous pollution15. These chemicals can cause excess vegetation and algae growth in lakes and rivers, depriving them of oxygen. This process, known as eutrophication, further harms biodiversity16.

Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause or exacerbate political conflict.
