Traditional Environmental Knowledge Uses

I agree with Professor Pena that societies such as the indigenous tribe of the Amazon in our Cajete reading have systems in place that were misunderstood and frankly underappreciated until recently, but now that researchers are finding that their environmental knowledge is in fact useful and has stood the test of time, what are the possible changes in Western culture that might take place? Will we or have we already begun shifting to more natural medicines, ways of disposing of waste, or even preparing/growing our food, or has this knowledge simply been an interesting story and something to think about and then eventually forget?
