They do mind, they mind a lot, it's just that for the vast majority of wildlife humans (land alterations, activity and presence byproduct) have an even larger effect than a touch of long-term radiation-induced lethal disease.
I caught a documentary while on a transatlantic flight about the Wolves of Chernobyl [1], and it discusses how the wildlife seems to be thriving with few to no ill effects.
This isn't me suggesting that irradiating the land with nuclear waste is good - far from it. But it does seem that nature is pretty resilient to it.
[0] they're not, though r-strategist will tend to be pretty resilient
In fact, though you said it much more intelligently with terminology I was unaware of, I was more suggesting that nature is more resilient in the face of nuclear waste/damage than one might expect, and I think that's what the parent is suggesting as well.
No more, no less. We should still be very cautious because there is undoubtedly a limit (perhaps even known?) as to how much punishment an environment can take. But Chernobyl's ecosystem does seem to show that when you take humans out of the equation, Nature can be pretty darn tough.
you're talking about the whole nature instead of the individuals. Place a bunch of humans near Chernobyl for several generations (30 years for wolves would be like 200 years for humans) and enforce the rule of quickly killing off any ill individual - natural thing in nature - and 200 years later you'll have a thriving human population there, and some alien would naturally conclude that humans "is more resilient in the face of nuclear waste/damage than one might expect".
