Going “GREEN” is in for just about everything these days to help save our Planet. In China many of the National Parks have already gone “Green” Above you see the famous Juizhaigou National Park in Sichuan province which has gone Green in a big way. The buses use natural gas and give out no pollutants, the toilets are modern and recycle wastes into the ground. Wooden paths are all through the park saving the land and plants. Air is fresh and clean and too there is a limit of 5000 people per day allowed into the park to keep it pristine. I spent a whole day in the park and did not see one scrap of paper or waste on the ground with plenty of waste bins located everywhere. What a fantastic example of what a National Park really can be.
