Important detail for the discussion --- methane is about 5 times as
powerful as a greenhouse gas as carbon dioxide is. Major sources are
paddy rice, termites, tundra, swamps, manure, and burping ruminants.
Burning methane as a fuel (it's easy to do in only slightly modified
internal combustion engines), however, produces very few greenhouse
gases.
Any intelligent (technological) life elsewhere within several hundred
light years already knows Earth has life --- the methane fingerprint of
our atmosphere is an absolute give-away for any one looking at spectra.
Once the first wave of our TV gets to them, they'll probably conclude
there's no *intelligent* life on this planet.
