the method of action is an important variable as well.
the wildlife of a wetlands that undergoes a drought has a chance to spring back once reintroduced to water.
the wildlife of a wetlands that is chemically poisoned will not spring back to life without either lots of time or remediation efforts.
'on the box' both situations look the same : no wildlife -- but they're not.
The reasons matter, more data than just statistical prevalence is needed here in order to assess the damage realistically in the attempt at scoring man-made disaster against natural disaster.
This is a good correction, thank you. Yes, modality matters.
