The Greater London Council last year spentPS750,000 to buy land and build 10 permanent wildlife refuges in the city. Over 1,000 volunteers have donated money and cleared rubble from derelict lots. One evening last year a fox was seen on Westminster Bridge looking up at Big Ben. For peregrine falcons, cities are actually safer than rural cliff dwellings . By 1970 the birds had died out east of the Mississippi because the DDT had made their eggs too thin to support life. That year, scientist Tom Cade of Cornell University began raising the birds for release in cities, for cities afforded abundant food. Cities can attract wild animals without turning them harmful. The trick is to create habitats where they can be self-sufficient but still be seen and...
