If we're leaving then leaving a thriving environment would be low on the priority list for anyone. Really the ultimate tragedy of the commons if you think about it... if the problem is so bad that our survival is reduced to zero, then it follows that there is no possible way to make our last act as a species to correct the garden to be some definition of "thriving". The fact is, something will thrive, it just won't be us, no matter what we do. Even nuclear winter will leave survivors that will adapt to the new wasteland.
