These environmentalists come off as quite selfish if I might say so. They take public land who belongs to all and redevelop it into their "dream" whatever it may be, and they do not care at all how it impact other people who previously used that public land or people who live nearby.
I am not a big fan of these rewilding policies. There are only a few open spaces left where one could previously take a relaxing hike (in Germany). I do not want to have to worry about wolves and bears and bison when I go for a hike in these places.
I really don't see how the benefits outweigh the costs.
