Europe Sowing the Seeds of Hunger

Europe is facing a hungry future unless it changes agricultural policies and makes farmers the main participants in agriculture research, a new report has found. And there is little hope of meeting Europe's recently announced goal of reducing the loss of biodiversity in ten years without making those changes.

Humanity Hitting the Resource Ceiling

Better living through using far fewer material resources is the only possible future, experts agree. Humanity is pressing up against the limits of a finite planet to provide resources like water, oil, metals and food, according to a new report released Thursday.

The Nuclear Cost Shell Game

The nuclear energy industry only exists thanks to what insurance experts call the "mother of all subsidies", and the public is largely unaware that every nuclear power plant in the world has a strict cap on how much the industry might have to pay out in case of an accident.

A Fatal Addiction to Plastic

"Be fantastic, don't use plastic!" chanted a troop of 10-year- olds from President Thomas Jefferson Elementary School in Honolulu at the conclusion of an international conference on the millions of tonnes of trash that enter the oceans every year, with serious consequences for marine life and habitats as well as to human health and the global economy.

Who Controls the Nuclear Control Agencies?

As Japan struggles to confront a nuclear disaster that could be the worst in history, it seems clear that any discussion about the safety of nuclear energy should address the independence of regulatory agencies.

Peak Water Has Already Come and Gone

Canadian Kevin Freedman is celebrating World Water Day Tuesday by living on 25 litres of water a day, instead of the North American average of 330 litres per day. And he has enlisted 31 others in his "Water Conservation Challenge" to go water- lean, using just 25 litres per day for cooking, drinking, cleaning, and sanitation for the entire month of March.

Japan Nuke Disaster Could Be Worse Than Chernobyl

A global nuclear disaster potentially worse than Chernobyl may be under way in Japan as hundreds of tonnes of highly radioactive spent nuclear fuel are open to the sky, and may be on fire and emitting radioactive particles into the atmosphere.

Save Climate and Double Food Production With Eco-Farming

Eco-farming could double food production in entire regions within 10 years while mitigating climate change, according to a new U.N. report released Tuesday in Geneva.

Enthusiasm For 2012 Earth Summit Lagging

Timed to coincide with the 20th anniversary of the 1992 Rio de Janeiro Earth Summit, the Rio 2012 Summit hopes to recapture the optimism of that earlier era.

Tourism Is Poisoning the Mexican Caribbean

The booming tourist industry along Mexico's Caribbean coast, particularly in the area of Cancún and the "Riviera Maya," is polluting the world's largest underwater cave system and harming the world's second largest coral reef, a new study has found.

Amazon Drought Accelerating Climate Change

Last year's severe drought in the Amazon will pump billions of tonnes of additional carbon dioxide (CO2) into the atmosphere, a new report has found.
