GOVERNMENTS, do you really want to stop global warming? Then start by banning biodegradable producs, and save the planet!

Biodegradable products, which slowly decay into inoffensive chemicals instead of clogging up landfills until the end of time, seem like they shouldn't have a downside. But one of those chemicals is apparently not so inoffensive: methane gas. If a landfill has high-tech methane-capture technology, then that's free fuel. But if they don't (and most don't), that methane is going straight into the atmosphere. And methane is actually a far worse greenhouse gas than much-derided carbon dioxide.
