The idea that you can travel not only for your own impressions, but at the same time to be helpful to society and nature, seems incredible. And ecotourism is just about that. Imagine that you can not only have a look at a new place, but also take part in an important project. For example, to help a local restaurant, volunteer in a nature reserve (if there is a lot of time for vacation) or go on a historical excursion, the proceeds of which are sent to help social minorities.
Big companies are also joining the idea of sustainability: air carriers, hotel chains, etc. For example, Royal Caribbean reduces its carbon emissions on cruise ships, KLM is working on reducing greenhouse gas emissions and noise pollution, and uses recycled materials in its meal service packaging. This extends sustainable tourism as an idea and makes it a global trend.
