The word "ecotourism" is a combination of ecology and tourism. The International Ecotourism Society describes ecotourism as "responsible travel to natural areas which conserves the environment and sustains the well-being of the local people". Thus, walking through a rainforest isn't truly considered ecotourism unless it helps the surrounding community, perhaps by providing jobs for local people or preserving the wildlife. Countries are gradually recognising that it is possible to make money while protecting their natural resources.

Costa Rica has been leading the ecotourism movement for some time. In April of 2012, TripAdvisor.com ranked Costa Rica as the most popular ecotourism destination. Over 25 percent of Costa Rica's land is covered in lush national parks as a result of its conservation efforts. Its tourism sector employs thousands of people and brings in over $1 billion a year.

Unfortunately, people in the industry sometimes exploit the "ecotourism" label in their drive for profit. This brand of ecotourism isn't always conducted in the most responsible way, and may damage the environment it seeks to protect. One concern is that the ecosystem may be negatively impacted by the excessive number of people visiting these natural areas. Ecotourists tend to seek out locations with the rarest animals and plants; even if they take care not to upset the environment, their presence could put pressure on the most delicate living organisms. The interactions between people and animals pose another problem. In one Costa Rican national park, wild monkeys feed on garbage left by visitors and even aggressively steal food from them.

Although it is easy to be critical of the ecotourism sector, it is important to be positive as well. There will never be "pure" ecotourism - we can't expect zero negative effects on the ecosystem. It is also implausible to think that humans won't travel anywhere accessible to them.
