With activists killed in Brazil, Cambodia, the Philippines, and elsewhere, 2012 may have been the worst year yet for violence against those working to protect the environment.
No broad-based international agreement on sharing rivers currently exists, even though much of the world depends on water from rivers that flow through more than one nation. But that may be about to change, as two separate global river treaties are close to being approved.
On issues ranging from genetically modified crops to nuclear power, environmentalists are increasingly refusing to listen to scientific arguments that challenge standard green positions. This approach risks weakening the environmental movement and empowering climate contrarians.
The West African nation of Ghana prohibits small operators using chainsaws from logging its forests, but it permits the export of timber cut at large sawmills.
Proponents of this nuclear technology argue that it can eliminate large stockpiles of nuclear waste and generate huge amounts of low-carbon electricity. But as the battle over a major fast-breeder reactor in the UK intensifies, skeptics warn that fast-breeders are neither safe nor cost-effective.
The Rio+20 Summit produced a largely meaningless document that failed to address the daunting environmental challenges the world faces.
With great fanfare, the United Nations announced in March that the world had reduced by half the proportion of people drinking unsafe water, meeting a critical development goal five years ahead of schedule. But a closer look reveals that the facts simply do not support this claim.
A British scientist argues that global warming could lead to a future of more intense volcanic eruptions and earthquakes. And while some dismiss his views as preposterous, he points to a body of recent research that shows a troubling link between climate change and the Earth’s most destructive geological events.
