A new apartment complex in Germany is intentionally growing an algae farm on its facade, in order to power the building. The hope to use the green slime to produce the building’s heat, as well as cool the building. It’s a new definition of "green!"

Will we see more green buildings in the future? In the April 25th edition of the New York Times, David Wallis quotes the building’s publicist, Rainer Muller, as saying, "Using algae as an in-house energy source might sound futuristic now, but probably will be established in 10 years."

The algae are farmed on adjustable louvers which cover the building’s surface and are fed liquid nutrients and CO2.

Patrick Moore help found Greenpeace in 1971, but today he’s pushing GM foods and nuclear power plants. And the Sierra Club is being taken over by anti-immigration activists. What’s going on here?

Drake Bennett writes in wired.com that despite campaigning in the past against nuclear testing, Moore joined the other side in 1986. Today he supports many of the interests he once fought against, such as the timber and plastics industries. He says the Amazon rain forest doesn’t need protection, the Three Gorges Dam in China was a great idea, and that opposition to genetically-modified foods is dangerous.

Evolution scientists in London warn of the spread of a global ?pest and weed? environment, with animals and plants such as rats, cockroaches and dandelions flourishing at the expense of more specialized wild species.

They say that in the next 5 million years, short-term evolution will favor species able to thrive in the margins of human settlements. They also warn that the decisions made in the next few decades will dictate the future course of evolution.

In a startling wake-up call, the group of international scientists compared the present mass extinction of species on earth to past mass extinctions. In the past, it took approximately 5 million years for biological diversity to reassert itself.

New evidence from satellites orbiting the Earth has put an end to an doubts about whether greenhouse gases are actually increasing.

Until now, researchers depended on ground-based measurements and theoretical models to measure the increase. New sets of data taken from two satellites orbiting the Earth have now provided the first directly observable evidence of a rise in greenhouse gases.

?It?s the first time that we have seen observationally that these changes are really having an effect on the radiative forcing of the climate,? said Dr. Helen Brindley, an atmospheric physicist at Imperial College in London. Radiative forcing is the measure of the climate effects of greenhouse gases.
