That's possibly the most clueless statement I've read on the net this month-and I read a lot.Actually the native or first nations peoples are miles ahead when it comes to environmentalism....
FYI-Indigenous societies had small populations to care for yet people overused and starved themselves as often as not-the archaeological record shows this time and time again-see the ancient Mayans for one glaring example.
As far as trash since everything their organic waste was no problem and whatever stone they used is handy for us today to study their long gone societies.
And anyone visiting a native reserve in Canada knows the meaning of the term dump-even the Capilano Reserve here in Vancouver is littered with garbage-the streets are choked with plastic rubbish and they are one of the if not the richest band in the country.
