clouds of methane over scotland

[ewx]

Mr Woodall said: "Plastic bags do not degrade, and thank goodness for that. When things do degrade they produce CO₂ and methane, the most potent green house gases.

"What will happen is that people will turn to buying paper and retailers will provide paper carrier bags which will degrade and there will be clouds of methane over Scotland."

Now I don't know exaclty what the relative environmental effects of plastic and paper bags over their entire life cycle amount to (and Mr. Woodall's views may be biased), but perhaps carbon sequestration through landfill of cheap consumer goods is an idea whose time has come?
