erosion

bare soil becomes exposed and is blown. sprinkler and spray irrigation also contribute

Salinization

the mineral salts dissolve in soil water concentrates after evaporations

monoculture

a single crop species is grown in a field, often year after year

agrobiodiversity

the genetic variety of animal and plant species used on farms to produce food

concentrated animal feeding

large-scale industrial agricultural facilities that raise animals in high density, often in confined spaces, for meat, dairy, or egg production

aquaculture

controlled cultivation of aquatic organisms, like fish, shellfish, and aquatic plants, in various water environments for commercial, recreational, or scientific purposes, similar to farming on land.

CAFOs

agricultural facilities where animals are kept and raised in confinement, typically for meat, dairy, or egg production.
