California brush fires are caused by environmentalists.
They wont allow proper management of the forestry so they turn a good chunk of the state into a giant tinder box.
Guess who ultimately picks up the tap for the massive fire suppression costs? That pink foam aint cheap.
Especially when you have to airdrop it in.
The same environmental whackjobs that want to save the trees, have no problem with the chemicals the pink foam leaches out into the water and soil. Hypocrites huh?
