Three U.S. consumer groups petitioned the Food and Drug Administration on Tuesday to subject a new genetically engineered salmon to a more rigorous review process than is now in place before the fish can be approved as safe to eat.

The fish at issue, AquaBounty Technologies' AquAdvantage salmon, is currently classified as a new animal drug for the purposes of FDA review.

British Airways, Qantas and other airlines are calling on governments to find a swift resolution to a political dispute over the European Union's carbon scheme, because the deadlock may create competitive distortions.

Since the start of 2012, EU law obliges all airlines using EU airports to be included in the EU Emissions Trading System (ETS), the 27-nation bloc's main policy to fight global warming as it caps emissions on over 11,000 power and industrial plants.

U.S. scientists using satellite data have established a more accurate figure of the amount of annual sea level rise from melting glaciers and ice caps which should aid studies on how quickly coastal areas may flood as global warming gathers pace.

The Grand Canyon will soon ban the sale of bottled water, responding to concerns that empty plastic bottles scattered around the park are spoiling views of the natural wonder.

The National Park Service has approved a plan that would eliminate the sale of bottled water within 30 days, after nearly $290,000 was spent to install 10 water stations inside the park. Visitors can use the stations to refill their own water bottles, which they can tote in from the outside.

Slash-and-burn agricultural practices, banned by governments because of the risk of uncontrolled fires, provide better growing conditions for valuable new trees than more modern methods of forest clearance, a study suggests.

Starting in 1996, researchers cleared 24 half-hectare areas of tropical forest in Quintana Roo state, in southern Mexico, using three methods: clear-felling, where most of the trees are cut down; bulldozing; and slash-and-burn, a practice common among smallholders, in which trees are felled, left to dry and then burned, to prepare the land for agriculture.

With the European Union facing global flak over imposition of a green tax on all aircraft flying in its skies, world airlines’ body IATA has warned European airlines of “retaliatory action” by non-EU nations if a global solution was not arrived at soon.

The global community plans to send individual letters to the European Union protesting its decision to implement the Emission Trading Scheme (ETS) on airlines operating to the 27-nation bloc.

Official sources told Business Line that with more than 100 protest notes extending from the US to India landing at its doorsteps, there will be added pressure on the EU to take note and some action taken.

With European Union (EU) facing global flak over imposition of a green tax on all aircraft flying in its skies, world airlines’ body IATA has warned European airlines of ‘‘retaliatory action’’ by non-EU nations if a global solution was not arrived at soon. ‘‘Time is not on our side. Airlines from Europe may face some retaliatory action.
