Has the Gulf of Mexico recovered from deepwater horizon? How many ecosystems were lost permanently? Animals living in the exclusion zone have a life expectancy 30% lower than those in the surrounding area (based on the last paper I read about the topic) so it's not an acceptable risk for humans but it's still peanuts compared to the damage that single spill did to the Gulf ecosystem.

It's an extension of the cognitive bias you point out. Just because we humans find the area too risky to inhabit afterwards doesn't mean that the damage made a meaningful impact on the survivability of our planet.
