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 very environment it seeks to protect. One concern is that the overwhelming number of visitors to these natural places (especially in the high season) has a negative effect on the ecosystem.
Ecotourists tend to seek out places with the rarest animals and plants.
even if they take care not to disturb the environment,
their presence could put pressure on the most frail of living things.
Another problem is the interaction between animals and humans.
At one national park in Costa Rica ,wild monkeys feed on garbage left by the visitors and even aggressively steal food from tourists.
