Ecotourism relies heavily on the environment----without it , there would be no tourism at all.
In order to maintain ecotourism and prevent the degradation of environment, tourism operators should adopt the environmental friendly concepts into their business to keep the ecotourism alive.
an operation’s environmental performance must not increase costs or reduce comfort and convenience.
when simple solutions are not available and more costly treatment methods may need to be considered---
result may be the intangible benefit such as admiring from tourist (value added to the product)
the responsible actions (of tourism operators) such as energy conservation, waste minimization can be an interesting selling point (put in the advertisement)
