Global environmental challenges
Would you eat a genetically modified fish? What about pork from a pig with mouse genes? Beef from cattle with genes spliced to resist “mad cow” disease?
These are questions Americans may soon have to answer for themselves if the U.S. health regulators allow the sale of a genetically engineered salmon. The company that makes it, Aqua Bounty Technologies Inc <ABTX.L>, expects an agency decision by year’s end.
The biotech says its Atlantic salmon grows nearly twice as fast as normal salmon and could help Americans get more locally farmed fish. That could cut down on U.S. imports of roughly $1.4 billion a year in Atlantic salmon from other countries such as Chile while also easing pressure on wild Atlantic salmon in the nation’s Northeast.
But environmentalists and consumer advocates are concerned about what could happen if such altered fish were to escape or be released in rivers or off-shore salmon farms. They also worry about the health effects of eating such modified fish.

How do you solve a problem like David Miller?
According to the Chicago Tribune, he is the Illinois representative who last month, with little fanfare and notice at the time, attempted to modify legislation to include tire burning in the state’s definition of renewable energy.
Natural gas is regarded as a relatively clean source of energy but there is mounting evidence that it has a dirty side.
London's transport bosses are telling travellers on the tube system to beat the heat by carrying a bottle of water with them when they venture underground.
But how many of us are refilling our bottles with tap water rather than pouring money down the tube -- not to mention the cost of recycling the plastic bottles -- by buying a new bottle of water each day?
A study issued on Thursday hints that it could.
A scuba diver in the South China Sea off Malaysia (above, picture by David Loh of Reuters News) might write a blog if corals looked damaged by ‘bleaching’ – algae that give reefs their colours can start to die off because of higher sea temperatures. It might just turn out that divers far away in Australia, the Caribbean or elsewhere were starting to notice the same thing — perhaps setting off alarm bells about global warming.
