One of the most interesting and most positive trends in the travel industry has been the growing popularity of green travel.
This has taken on many forms. Some people choose to travel in very responsible ways, trying to minimize the foot print of their travel. They by carbon off set credits, travel to ecologically responsible places and generally try to tread as lightly as possible while also experiencing the world.
Other people just want to travel to beautiful natural settings and have an outdoor experience in contrast to going on a cruise or staying in a resort. I think that both forms are positive trends. Travel is a very wasteful process as fun as it may be. If we would all make the decision to travel more responsibly it would go a long way towards the health of the world.
