I can't imagine that approaching ecology from a perspective of re-wilding will be of much benefit. The wild is happy to take over a space that isn't kept civilized (for instance, the exclusion zone around Chernobyl), so you quickly end up with a situation where you want to be able to predict the consequences of any actions you take against the existing ecology, which is anyway how we are managing 'wild' spaces.

Unfortunately many of the effects of humans are long-lasting. The elimination of buffalo, for instance, or the loss of most wolf populations in North America which lead to the explosion of deer, IIRC. I am quite interested in the possibilities of selective breeding to replace extinct species, and the major die-off currently happening could have negative effects we have not yet even begun to see.
