Get all the liberals to stop breathing out CO2. They are killing the planet:-)
Liberals contribute 70% of all the CO2.
You might be on to something there. Suppose some scammer came up with a product (a bag) that promised to neutralize CO2 if you exhale into it.
Many liberals would buy that bag. The scammer would get rich. And we would be able to identify the stupidest among the liberals because they'd be carrying that bag around.
