When it comes to tracking eels, citizens make a difference
[audio:http://wamcradio.org/EarthWise/wp-content/uploads/2012/03/EW-05-04-12-Eels.mp3|titles=EW 05-04-12 Eels]
American eels are born way out in the Atlantic Ocean, between Bermuda and Puerto Rico. Juveniles, known as “glass eels,” migrate to freshwater habitats like the Hudson River when they are just a couple of inches long. There, they can spend up to twenty years maturing. They return to the ocean only to spawn. [Read more…] about When it comes to tracking eels, citizens make a difference

Raising livestock outdoors is humane, but pasture-raised animals can cause environmental problems
[audio:http://wamcradio.org/EarthWise/wp-content/uploads/2012/03/EW-04-25-12-Hog-Waste.mp3|titles=EW 04-25-12 Hog Waste]
Let’s focus on pigs. Most of the pork we consume comes from massive indoor facilities where a large number of animals are raised in a relatively small space. These operations are notorious for pervasive odors and for causing air and water pollution. For ethical reasons, many people prefer to buy pasture-raised pork.

Fertilizer helps feed the world – but the way it's produced can be harmful
[audio:http://wamcradio.org/EarthWise/wp-content/uploads/2012/03/EW-04-18-12-Fertilizer.mp3|titles=EW 04-18-12 Fertilizer]
Until the Industrial Revolution, we increased fertility in our farms and gardens by applying animal manure, compost, or minerals mined from the earth. Then, scientists developed a method to capture nitrogen for use in fertilizer. Synthetic fertilizer is responsible for the so-called Green Revolution that increased crop yields and supports the earth’s growing population.
