New Zealand cities, where 80% of us live, are polluted just like overseas cities of comparable sizeThe rivers are full of run off from farms and they spray toxic poisons around the bush to kill possums, like 1080 pesticide.It looks lovely but that part of the country is hard to get to. Most of us look at cities of a few hundred thousand all day and see farms when you go fro a driveit is very beautiful and I take if for granted all the time.....
