[Stoves] Stove Conf in Poland this month [COMMUNIQUE, non-paper]

[Nikhil Desai]

Crispin:

Ever wondered how cognitive dissonance is recognized?

We wouldn't have a stove movement for boiling water instead of cooking.

Or a campaign for subsidizing gas and electric companies - phenomenally
corrupt just about anywhere - in the name of aDALYs.

What is cooking but moral corruption of public health?
