Ecotourism

Hi, everyone.

Today, I found an article about ecotourism.

I thought ecotourism is good before I studied about it. However, I don't think so now. For the first time, I thought tourists can stimulate a regional economy because if they visit somewhere, they spend a lot of money there.  Also, they can understand about environment. But tourists bring not only advantage but also disadvantage like this article. Also, not only tourists. Human build many condominiums, houses and hotels. So sea turtles misunderstand artificail light and moonlight. In fact, sea turtles is an endangered species. I think it is difficult to be compatible with continuation of regional resouces like nature and achievement of tourism.
