During the Summer of 2007, a friend (21 years old) and myself (22 years old) traveled to Tibet together to teach english at an orphanage. during our stay, we saw how the school utilized a very sanitary mini-landfill, and kept their water source and waste systems very well separated. The nearest town from the orphanage (maybe 4 miles) had a much more devastating situation. Trash clogged the waterways, there was no waste removal systems or landfills. The very holy mountain the town was at the base of was also littered with trash, even from the monks!
