There are critics who would like to limit tourism drastically or abolish it. I don't agree with that solution. I thinks there are other and better solutions to improve tourism. For example developing and promoting new forms of tourism, which will bring benefit to tourists and those who live off tourists. Those new forms of tourism must not be guided only by economic and technological considerations. They also must be better for the environment.
If you travel in Europe, it is better for the environment to take the train or the bus instead of the plane. You would be shocked how much fuel a plane uses. And like we all know, air pollution is very bad for the environment.
If you go on a vacation in your own country, you maybe could take your bike. No air pollution and you have your own transport on your vacation, you can go wherever you want and where you want.
