<strong>Dear EarthTalk: I've been hearing about the popularity of milk sold in bags (as opposed to plastic or cardboard cartons) in India, Europe and Canada. What are the environmental advantages to milk in bags, and do you think it will catch on in the U.S.? And what other options are out there for milk drinkers trying to be green? -- Paul Howe, San Francisco, CA</strong>
Electronic waste, or “e-waste” as it’s called, is a growing problem in the United States and abroad, as obsolete or broken computers and other electronic equipment are taking up increasingly precious amounts of landfill space and potentially leaking hazardous substances into surrounding ecosystems.
Food waste is a huge issue in America, especially in light of the growing divide between the profligate rich and the hungry poor. According to the U.S. Department of Agriculture’s Food Loss Project, we throw away more than 25 percent—some 25.9 million tons—of all the food we produce for domestic sale and consumption. A 2004 University of Arizona study pegs the figure at closer to 50 percent, finding that Americans squander some $43 billion annually on wasted food. Lead researcher Timothy Jones reported that on average, U.S. households waste 14 percent of their food purchases. He estimates that a family of four tosses out $590 per year in meat, fruits, vegetables and grain products alone.
