Depending on the agricultural practice and location, there are several possible negative effects of modern agriculture. One example is found in farming operations practiced without proper knowledge and care, which become a threat to ecosystems and species.
According to the World Wildlife Fund, as the demand for food rises, there are more and more intensive single-crop farms, leading to a loss of biodiversity. When natural vegetation is removed and converted to agricultural land, erosion occurs and carries away fertile soil. Use of fertilizers and pesticides can lead to groundwater source pollution. Using genetically uniform varieties damages the genetic diversity of food, meaning less adaptation and survivability potential. Agriculture affects food supplies and ecosystems and should be practiced with care and attention.
