"Negative externality" is a word meaning that something valuable is destroyed but it's no one's private property.

If it were property, it could have a price, and compensation of damage to it could be sought. But not everything is easy to price in a market: e.g. a national park.

Anyway, if damage is real, or a risk is real, a court could look at it. If not people themselves, an insurance company could, in some cases.
