I have just returned from a trip to Vietnam which included 2 days on a traditional Vietnamese junk boat in Halong Bay. The site itself is breath-taking, but unfortunately, there is little respect for nature shown by those operating the tour boats. I repeatedly saw boat operators throw their garbage overboard into the waters. These are the people who survive on tourism and ought to care more about protecting the very site which is bring the tourists to them in bus-loads. It was sad to see this and I hope the government forces people to clean up their act.
