Is there room for nature in our cities?
By Peter Fisher, RMIT University and D Trainham, RMIT University Welcome to the CBD. Take a look at all the glass masonry and asphalt. The streets are canyons. Apart from a tree in the footpath, or a Peregrine Falcon way overhead, there’s little nature to be seen. Nature is absent in these landscape...
