Over the past several years honeybee colonies have declined dramatically. There is no consensus over a single cause, and in fact, scientists point to multiple reasons for this problem. An important, yet often overlooked factor is basic land use decisions. Listen to learn about the importance of the symbiotic relationship between honeybees, flowers and humans, and what kids can do to help promote honeybees and other pollinators.
A new source of energy is being developed by using Michigan's industrial food waste. Using existing technology for converting manure into electricity, these anaerobic digesters are doing their work on pudding packs and canned peaches, among other delicacies. Listen to learn how they are turning waste into electricity.

Carbon exists in all living things, including proteins, DNA, and fats. When living things exhale, the result is carbon dioxide. As our world develops, we produce more carbon dioxide with the burning of fossil fuels and the use of cars, trains, and planes. This gas is causing an imbalance in the atmosphere which affects the warming of the planet. Listen to hear how much carbon dioxide humans are responsible for and the effects of global warming.

The same methane gas emitted from humans is also produced by the same bacteria that lives in old pizza crusts, curdled milk, and other discarded food. Scientists have found ways to convert the methane gas from old food into energy. Several cities are already converting waste into energy, listen to this story to learn how New York City is trying it out.
