Should this surprise you?: Hollywood is one of California's top air polluters:

Big-budget special effects and disposable sets help make Hollywood one of California's top air polluters, pumping out 127,000 tonnes of ozone and diesel emissions a year, a study found.

[...] The institute found that the industry emits 127,000 tonnes of ozone and diesel particulate pollutant emissions from idling trucks, generators, special-effect fires and earthquakes, and the demolition of sets with dynamite and other methods.

Hollywood produced more pollution than four other industries: aerospace manufacturing, apparel, hotels and semiconductor manufacturing, the study found.

Defining the problem is for our betters to do; being forced to be part of the solution is for the little people.
