2 paper mache statues burned amongst 60,000 people is a tiny amount per person. They created more pollution getting there, or cooking food for all those people.

But people don't have any perspective. They say "der, lookit da big fire, lookit da pollution, der"

Maybe some went to burning man and didn't know or think about global warming. Now that you have brought it to their attention perhaps they will learn about it and curtail such activity in future events.
