Electronic Waste Created by Outdated Cell Phones

Technology Environment

Most people want to buy new phones with the latest technology, but new devices lead to electronic waste, or e-waste, when old phones are discarded. Phone companies used to offer free phones with contracts, which meant people got new phones every two years. Now contracts are changing and there are new ways people are thinking about phones. One way is the modular approach, where the components are detachable and replaceable. Another is to create longer-lasting phones that are better for the environment.

Cow Burping and Greenhouse Gases

conservation

Greenhouse gases trap heat in Earth’s atmosphere, contributing to climate change. One of the most common greenhouse gases is methane. In the United States, cars and industry are the primary sources of greenhouse gases. In Africa, which has more agriculture than industry, burping cows are the main producers of methane gas. Researchers have found that African and American cows are actually quite different from each other in the amount of methane in their burps. African scientists are studying how cows’ diets affect their methane production. Listen to hear how cow burps affect the environment.

Permafrost is frozen soil that has preserved things such as ancient animal bones and centuries-old icebergs. Permafrost contains twice as much carbon as is currently in Earth's atmosphere and it also preserves old bacteria. When it's defrosted the bacteria eats dead plants and animals turning their carbon into gases such as carbon dioxide. As the permafrost warms, the microbes are releasing gases contributing to further warming. Listen to learn more about this warming cycle.
