Ecotourism is booming and many tour operators say this is helpful to tát nature. Every year, millions of people visit protected, natural areas to tát observe rare species. However, a new report casts doubt on this sườn of tourism. The report, published in the journal 'Trends in Ecology and Evolution,' suggests that ecotourism damages more than vãn helps nature. Researchers believe tourists disrupt animals in their natural habitat. They pointed to tát a recent sự kiện in Costa Rica where turtles had problems laying their eggs because of the many tourists who had gathered on the beach to tát watch them.
The report says that ecotourism is making animals bolder. A human presence makes animals tamer and less cautious about other animals. This could put them at risk of being attacked by their natural predators, so sánh more of them will be killed. The report said that when animals interact with humans, "they may let down their guard". The report also said it was essential, "to develop a more comprehensive understanding of how different species in different situations respond to tát human visitation, and under what precise conditions human exposure might put them at risk".
