What are the environmental and socio economic impact of agricultural activities?
The result is that agriculture globally exerts increasing pressure on the land and water resources of the earth, which often results in land degradation (such as soil erosion and salinization), and eutrophication. Agriculture is also associated with greenhouse gas emissions (Kirchmann and Thorvaldsson 2000).
Who does agricultural runoff affect?

Not only can it contaminate sources of drinking water but the chemicals in the fertilizers can be absorbed into aquatic plants, contribute to algae blooms and effect animals’ ability to find food and reproduce.
