Artificial Coral Offers Solution to Endangered Reefs

Reuters - Innovations Video Online (Oct. 7, 2014) — With recent studies showing the world's oceans acidifying at an accelerating rate, scientists say coral reefs are at risk of dying out. But a student at London's Royal College of Art has come up with a possible solution. She has designed an artificial coral that, when placed in a reef, slowly dissolves over time releasing an alkaline solution to counteract the acidity. Matt Stock has more. Video provided by Reuters

Solar Sister Solar Power Is Empowering Ugandan Women

Deutsche Welle (Mar. 4, 2013) — 95 percent of the population in Uganda has no electric power in their homes and relies on paraffin lamps for lighting. But not only is kerosene expensive, it's also a serious pollutant. Set up in 2010, the project Solar Sister has now provided almost 32,000 Ugandans with solar technology - and trained women as saleswomen. They're earning a living, helping their community and protecting the environment. In the course of ten years, a solar lamp saves over 600 liters of kerosene and that means CO2 savings of 1.5 tons. Solar Sister hopes to have helped save 10 million tons of CO2 over the next ten years.

Agriculture and Climate Change What Can Farmers Do to Protect the Environment?

Deutsche Welle (Sep. 24, 2012) — The impact of climate change on international food production has long been underestimated. New studies looking at the effects of extreme weather scenarios on global food prices in 2030 project that the consumer price of corn and other grains could increase by as much as 140 percent. Moreover, scant attention is paid to the fact that the agricultural industry itself contributes to climate change. Experts maintain that the sector could theoretically reduce its CO2 emissions by some 6 billion tonnes a year. But how?
