Green Options

Scientists have been warning us that global warming may severely threaten the survival of marine populations for several years now. But in a new study, published in Science this past Friday, they may have just found the ocean’s equivalent of the canary in the coal mine when it comes to fluctuating ocean temperatures. There’s just one little problem. This canary is worth $500 million.

The algae! Yes – the same slimy brown-green ‘plant’ that makes a pond or a lake look yucky – is the creating a great buzz as the most promising source of alternative energy. And now nanotechnology is being leveraged to add some more zing to the promise!

A project of SEA (Social Environmental Aesthetics) at Exit Art, “Vertical Gardens is an exhibition of architectural models, renderings, drawings, photographs and ephemera that depict or imagine a vertical farm, urban garden or green roof.” The exhibit features over 20 projects, both imaginary and real, by artists and architects envisioning solutions for building greener urban environments.

Details for the FREE two-day event (featuring eco architects, artists, professors, and poets) at Exit celebrating Earth Day 2009 are as follows:

A team of UK scientists have developed a shoal of robotic fish, which will soon be released into the sea to detect water pollution.

The robots (video), shaped like Carp, will be set free off the coast of Gijon in northern Spain. If the trial proves successful, the fish could be used in rivers, lakes and seas across the world.

Even though sea turtles are legally protected, their populations have been drastically dwindling worldwide. All marine turtle species are listed as endangered, except the Loggerhead, which is listed as threatened. Sea turtles face a number of deadly threats, including poaching, fishing, rapidly shrinking habitat, human encroachment, polluted oceans and global warming. However, in San Francisco, Nayarit the turtles are beginning to make a slow resurgence.

A lobster, thought to be up to 140 years old, is to be released into the Atlantic Ocean, after briefly becoming an unconventional mascot at a New York City restaurant.

PETA found out about the plight of the 20 pound crustacean when a diner at NYC’s City Crab & Seafood called to say it was being kept in the diner’s tank. PETA’s Ingrid Newkirk praised the restaurant, saying, “We applaud the folks at City Crab and Seafood for their compassionate decision to allow this noble old-timer to live out his days in freedom and peace.”

A team of UK scientists have discovered a natural process that could delay, or even end, the threat of global warming.

The researchers, aboard the Royal Navy’s HMS Endurance, have found that melting icebergs off the coast of Antarctica are releasing millions of tiny particles of iron into the southern Ocean, helping to create huge ‘blooms’ of algae that absorb carbon emissions. The algae then sinks to the icy depths, effectively removing CO2 from the atmosphere for hundreds of years.

According to lead researcher, Prof. Rob Raiswell of Leeds University, “The Earth itself seems to want to save us.”

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.
