Shall we protect Nature as it is,
reserve some land, ocean, resources
for coming generations, for our children’s children?
Shall we, or shall we not? In words, or in action?

(quote) Approval of oil drilling in Chukchi Sea fails to include recent science and violates laws that protect clean air, water, and ocean resources. Oceana, together with Arctic communities and other conservation groups filed a legal challenge in the Ninth Circuit Court of Appeals to the Minerals Management Service’s (MMS) approval of Shell Offshore Inc.’s proposed exploration drilling in the Chukchi Sea. The groups argue that MMS and Shell have not complied with federal laws that require thorough analysis of potential impacts and protections for clean air, water, and marine life.  read more »

Green sea turtles, whose ancestors evolved on land and took to the sea to live about 150 million years ago, are one of the few species so ancient that they watched the dinosaurs evolve and become extinct.

World's biodiversity crisis needs action, says UN. With species extinction running at about 1,000 times the "natural" or "background" rate, some biologists contend that we are in the middle of the Earth's sixth great extinction - the previous five stemming from natural events such as asteroid impacts.

The United Nations has launched the International Year of Biodiversity, warning that the ongoing loss of species around the world is affecting human well being. Eight years ago, governments pledged to reduce the rate of biodiversity loss by 2010, but the pledge will not be met.  read more »

BBC: Ben Wallace, an ex Army officer & former overseas director in the security & intelligence division at UK defense firm QinetiQ - one of the companies making the full body scanner technology - said, the "passive millimetre wave scanners", which QinetiQ helped develop, probably would not have detected key plots affecting passengers in the UK in recent years. Mr. Wallace said the scanners would probably not have detected the failed Detroit plane plot of Christmas Day. He said the same of the 2006 airliner liquid bomb plot and of explosives used in the 2005 bombings of 3 Tube trains and a bus in London.  read more »

The floating mass of plastic junk - almost the size of the Northern Territory - in the Pacific is an environmental catastrophe: "...the nature of the problem is so immense and the fact it doesn't fall under the jurisdiction of any particular country means as a cause it's kind of like the runt of the litter, something that no particular country wants to take responsibility for." According to the United Nations Environment Program, it causes the deaths of more than a million seabirds every year, as well as more than 100,000 mammals including whales, dolphins, turtles and seals.

The prototype of a solar-powered plane, the size of an Airbus and the weight of a mid-sized car, destined for a record round-the-world journey has made its 1st trip across a runway. The plane covered at least 2km at speeds of up to 5 knots on the landing strip in Switzerland. This test run saw the Solar Impulse plane outside its hangar for the first time, with tests of its motors and computer. As wide as a jumbo jet but weighing just 1,500 kg, the plane's maiden flight is scheduled for February in 2010, and a final version will attempt to cross the Atlantic in 2012. HB-SIA’s mission is to demonstrate the feasibility of a night flight making sole use of solar energy. It is a “no frills” plane built solely for verifying our technological choices. It is a true “flying lab”. The results gained from it will be used for optimizing the construction of the HB-SIB, whose mission it will be to fly around the world without fuel and with zero emissions as from 2012.
