Rhino horn and tiger blood: conservation in the Mekong

When Australians think of the Mekong they think cheap holidays or Vietnamese restaurants. Biodiversity-wise however, the Mekong is a frontier, a place where biological riches collide with human pressure. This month ten remarkable freshwater worms were described in Thailand, while in 2011 scientists found 126 new species, including five mammals. At the same time the […] … learn more→

Wind surpasses nuclear in China

Wind has overtaken nuclear as an electricity source in China. In 2012, wind farms generated 2 percent more electricity than nuclear power plants did, a gap that will likely widen dramatically over the next few years as wind surges ahead. Since 2007, nuclear power generation has risen by 10 percent annually, compared with wind’s explosive […] … learn more→

Warmest decade on record brings record temperatures and weather extremes

In recent years weather events have whiplashed between the extremes of heat and cold, flooding and drought. Carbon dioxide and other greenhouse gases—largely from the burning of coal, oil, and natural gas—have loaded up in the atmosphere, heating the planet and pushing humanity onto a climatic seesaw of weather irregularities. High-temperature records in many places […] … learn more→

New era of food scarcity echoes collapsed civilizations

The world is in transition from an era of food abundance to one of scarcity. Over the last decade, world grain reserves have fallen by one third. World food prices have more than doubled, triggering a worldwide land rush and ushering in a new geopolitics of food. Food is the new oil. Land is the […] … learn more→

Overfishing threatens critical link in the food chain

The fish near the bottom of the aquatic food chain are often overlooked, but they are vital to healthy oceans and estuaries. Collectively known as forage fish, these species—including sardines, anchovies, herrings, and shrimp-like crustaceans called krill—feed on plankton and become food themselves for larger fish, seabirds, and marine mammals. Historically, people have eaten many […] … learn more→

Best of 2012: World forest area still on the decline

Forests provide many important goods, such as timber and paper. They also supply essential services—for example, they filter water, control water runoff, protect soil, regulate climate, cycle and store nutrients, and provide habitat for countless animal species and space for recreation. Forests cover 31 percent of the world’s land surface, just over 4 billion hectares. […] … learn more→

Expanding dust bowls worsening food prospects in China and Africa

When most people hear the term “dust bowl,” they think of the American heartland in the 1930s, when a homesteading wheat bonanza led to the plowing up of the Great Plains’ native grassland, culminating in the greatest environmental disaster in U.S. history. Despite warnings from researchers and some farmers, history repeated itself in the Soviet […] … learn more→

World nuclear electricity generation down 5 percent since 2006

World nuclear electricity-generating capacity has been essentially flat since 2007 and is likely to fall as plants retire faster than new ones are built. In fact, the actual electricity generated at nuclear power plants fell 5 percent between 2006 and 2011. In 2011, following Japan’s Fukushima Daiichi nuclear disaster, 13 nuclear reactors in Japan, Germany, […] … learn more→
