No one is trying to create an ideal ecosystem

They tell us that ecosystems that have lost just one or two species of large animals can behave in radically different ways from those that retain them.All over the world, new movements are trying to catalyze the restoration of nature in a process called rewilding. This means undoing some of the damage we've caused,reestablishing species which have been driven out,and then stepping back.There is no attempt to create an ideal ecosystem, to produce a heath, a rainforest or a coral reef.
