Small streams are threatened by urbanization, logging, and agriculture. Scientists have uncovered evidence that makes stream more important in land-use policies.
"Nitrogen runoff into waterways has become an escalating environmental problem over the last 50 years, but a recent study found that small streams are extremely efficient at removing excess nitrogen?as much as half of the nitrogen that enters them...Land-use policies up until now have focused on terrestrial solutions for inhibiting nitrogen pollution...[w]hat this study shows is that we can reduce the amount of nitrogen that is being carried downstream by maintaining streams and wetland areas."
