How does nonpoint source pollution affect the ocean environment and why point source pollution is often easier to manage than nonpoint source pollution?
Non-point source pollution affects the ocean when fluvial discharges encounter a coastal environment where accumulation is enhanced by the specific hydrodynamics and morphology of the coast line. Point-sources, such as effluents from industries can be treated at the source; moreover there is usually more specific legislation and guidelines that control these discharges.
