Conventional agriculture.
300
What are two benefits of rotational grazing?
Accepted answers: increases soil fertility, helps to control undesired plants (such as invasive species); more control of forage/pasture, saves money for the owner, allows the land to rest between grazing rotations, etc.

400

As runoff from rainwater and snowmelt move over and through the ground, they pick up natural and human-made pollutants that are eventually deposited into watersheds through lakes, rivers, wetlands, coastal waters, and even groundwater. What kind of pollution is this? 

Nonpoint source pollution.
