All activities generate heat, that's one of the tenets of thermodynamics - replicate over the planet's population and there's a big heating effect. I don't see why anyone would dispute this.
So instead of making protests and causing activity and therefore heat, environmentalists should just go and sit down in their chairs, and reeeeeeelaaaaax.
