Answer:
Non point sources
Step-by-step explanation:
A point source is usually a single known source of a pollution such as emission of toxic fluids from a company directly into water bodies.
Runoff of eroded soil and chemicals such as fertilizers and pesticides from cropland, feedlots, logged forests, urban streets, parking lots, lawns, and golf courses are examples of non point sources as there is no main known source of the pollution.
