Agrobiodiversity loss
Toxic to consumers and workers, causes bred resistance in pests, harms pollinators
Pesticides
Placing desired genes from one species into another organism, can increase nutrition, decrease price, and control pests
Genetically modified organisms
Soil degradation from over farming on the edges of arid regions
Desertification
Occurs when water in the soil is depleted leaving the minerals
Salinization
Meat with the largest increase in production over the last 60 years
Chicken
locations that allow for high volumes of meat production by raising a single species for food
