There are a few farmers with their own gassometer, some of the farms near us have 500-600 milk cows, just imagine how much methane could be used instead of going up into the atmosphere, burning methane gives no pollution I'm led to believe, some Russian airlines used to use liquid methane for fuelling their planes,

Some ecoists say that the cows are damaging our atmosphere does anyone have any information on this scenario ?

Sorry Davy, I'm obviously not quite as experienced or knowledgeable as you. Are you suggesting we invent a contraption (or perhaps already have) to catch cow farts? Or just stand behind them with a lighter when we want to warm our hands Apologies: my imagination works in cartoon pictures.
