Green Options

The Bush administration has taken steps to open the Californian coast to oil exploration and drilling in as few as three years. The move could potentially tap more than 10 billion barrels of oil, enough to power the U.S. for 17 months.

Anti-whaling activists aboard the Sea Shepherd vessel ‘Steve Irwin’ have covered a whaling ship with a smelly cocktail of rotten butter, methyl cellulose and indelible dye.

The unconventional sliming operation was carried out in a bid to intimidate the Japanese whaler, Kaiko Maru, into moving out of Australian Antarctic territorial waters. According to Peter Hammarstedt, the Sea Shepherd’s second officer, “this is one stinky, slippery ship.”

A UK engineer has invented a device that harnesses wave power to pump sea water uphill, from where it can flow downhill to create hydroelectricity, raising hopes of a cheap, abundant source of renewable energy.

In trials, the device, called the Searaser, has pumped water more than 160ft above sea level, using little more than the natural motion of the waves. There are now plans for a much larger version, capable of pumping to a height of more than 650ft.

Inventor Alvin Smith reckons that each full-size device would be able to pump enough water to supply electricity to 470 homes. He also calculates that a fleet of 43,000 could generate enough power for a staggering 20 million households.

A team of researchers have developed a color-coded bacteria that will make it much easier to detect oil-spills and other forms of environmental pollution.

During a recent sea expedition the team successfully used the bacteria, which contains a protein that glows blue when viewed though a simple light-detecting device, to detect oil.

Over the past few years we have sadly had to watch the Arctic ice concentrations drop significantly. Focus has been primarily centered on the Arctic Circle, but Greenland is also suffering from the increased global temperature.

And now, thanks to researchers from the Delft University of Technology in the Netherlands and the Center for Space Research (CSR) in America, a new and accurate picture of Greenland’s shrinking ice cap has been formulated.

Subsequently, the researchers have found that Greenland is currently responsible for an annual increase of sea levels of up to half a millimeter.

With high oil prices, dwindling fuel supplies and a growing pressure to reduce global warming, governments are looking for brilliant ideas. Why don’t consider the sea? Waves are a powerful source of energy and in the last years a growing attention is producing a wide range of prototypes. Machines of various shapes and sizes are being tested in last years to see how they could capture waves and tides to create “marine” energy.

A new experiment comes from Michele Grassi, researcher at the department of math at the University of Pisa, in the centre of Italy, who built a prototype of a wave-trapping machine.

It’s not only the Gulf of Mexico that’s suffering from “dead zones” caused by  excess nutrients, such as nitrogen and phosphorus used as fertilizers.

Marine dead zones are spreading in the Baltic sea, and that could cause the entire ecosystem to collapse for lack of oxygen.  Dire warnings from Lasse Gustavsson, Swedish head of the World Wildlife Funds branch in Sweden.

We’re at the beginning of June and it’s still raining. Despite this unmerciful weather, summer season is coming and Italian coasts are preparing to host bunch of tourists from around the world. Such as every year, a list of best beaches is revealed by the Blue Flag Programme, responsible for monitoring popular public beaches, resorts and marinas throughout the world. Criteria such as water quality, amenities and general safety, as well as nearby cultural attractions are all taken into account before a “Blue Flag” is awarded.

This year the Blue Flag programme, owned and run by the independent non-profit organization Foundation for Environmental Education (FEE), has declared Italy’s nicest beaches can be found in the Tuscany and Marche regions, with each region boasting 15 awards. Overall, 215 beaches in 104 Italian communities received a “Blue flag”, eight more than last year and 14 more than in 2006. While last year many southern Italian beaches failed to gain the coveted symbol because of problems with waste disposal, this year they have had greater success.
