Nutrient runoff

The Environmental Protection Agency is offering $14 million to fund projects that help reduce harmful runoff into Great Lakes waterways through the Great Lakes Restoration Initiative. That includes green infrastructure, farmer-led outreach and education, manure management on farms, and a market-based approach called “water quality trading.”

Voluntary conservation farming practices are measurably decreasing nutrient pollution in the Mississippi River Basin, and this good news: from the Midwest, all the way down the Mississippi River in the Gulf of Mexico. As Indiana Public Broadcasting’s Nick Janzen reports, the Indiana trend in conservation is reducing the pollution that creates harmful algae blooms and the gulf’s dead zone.

The Indianapolis Zoo, as part of the dolphin exhibit, has a video of dolphins swimming in the Gulf of Mexico. They’re swimming near a boat, pushing air through their blowholes.
