A national park battles pollution

The Great Smoky Mountains National Park bordering North Carolina and Tennessee is not only a natural paradise but also is home to 20,000 species of animals and plants. However, that park has some of the highest measured air pollution and the highest level of acid rain of any national park in the country.

Farmers are using an ancient technique to purify water

Like the ancient Amazonians of centuries past, farming companies today are using a carbon-rich material to enhance soils or purify polluted waste water. It’s called “biochar.” We take you to Florida, where farmers and geochemists are creating biochar through an age-old practice.
