Baltic clams and worms release as much greenhouse gas as 20,000 dairy cows

Scientists have shown that ocean clams and worms are releasing a significant amount of potentially harmful greenhouse gas into the atmosphere. The team, from Cardiff University and Stockholm University, have shown that the ocean critters are producing large amounts of the strongest greenhouse gases – methane and nitrous oxides – from the bacteria in their guts. The researchers estimate that this is equivalent to as much methane given off as 20,000 dairy cows. This is as much as 10 per cent of the entire Welsh dairy cow population and 1 per cent of the entire UK dairy cow population. click here to read the story 16:23
