Using plants to solve environmental problems
Problems in their communities suggested good research projects to three teens. Each wanted to tackle a different issue, from pollution to world hunger. To learn more about these issues, they turned to their local ponds, wetlands and gardens.

Ditching farm pollution — literally
An Indiana project shows how fighting fertilizer runoff can save farmers money, protect wild habitats and prevent harmful algae blooms.

Scientists Say: Microplastic
Bits of plastic smaller than five millimeters are called microplastics. They can end up in the ocean, where corals might mistake them for food.

Corals dine on microplastics
Plastic in the ocean is a growing problem. New research finds that corals may eat tiny bits of plastic, prompting new concerns about the health of living reefs.

Scientists confirm ‘greenhouse’ effect of human’s CO2
Government scientists link directly, for the first time, a boost in warming at Earth’s surface to increasing levels of carbon dioxide. Much of that gas has been released by human activities, such as coal burning and gas-burning vehicles.

Hellbenders need help!
Hellbenders already face threats such as habitat loss, pollution and disease. But climate change could make matters worse. And the problems facing hellbenders could spell trouble for more than just these giant amphibians.

Plastics at sea create raft of problems
About 5.25 trillion pieces of plastic float in the world's oceans, a new study finds. That's a problem. This 269,000 tons of plastic can choke, entangle and poison a wide variety of sea creatures.
