It depends on the kind. There are groups that would prefer to see human presence reduced to a speck so nature can thrive. There are groups that somehow care for one single bog or meadow but fail to see the bigger picture. There are also those that simply want to protect everything and do support large projects provided they fulfill a lot of regulations. There are also people such as myself who have given themselves to Realpolitik: Local environmentalism is pointless if global protection fails (some drama added for effect)
