Read the following passage and choose the best answer to each of the following questions from 23 to 30.
1. Ecotourism has become a popular way to explore the natural world, with activities ranging from safaris to whale watching. It promises a sustainable way to appreciate wildlife while contributing to conservation. However, questions remain: does ecotourism truly benefit endangered species, or could it be causing harm?
2. A recent study published in PLOS ONE looked at the impact of ecotourism on various species. On the positive side, species such as the great green macaw in Costa Rica, African penguins, and golden lion tamarins in Brazil have benefited from ecotourism. Tourism funds have helped protect their habitats and support local conservation efforts. The study suggests that when managed well, ecotourism can lead to substantial conservation benefits, including habitat restoration and anti-poaching activities.
3. However, the impact of ecotourism varies by species and region. For instance, while some species thrive under ecotourism's influence, others do not. Orangutans in Sumatra, for example, continue to suffer from the effects of logging despite small-scale ecotourism efforts. Similarly, in New Zealand, ecotourism is exacerbating the problems faced by sea lions, as increased human presence disrupts their natural behavior.
4. The research highlights the complexity of ecotourism's effects. In some cases, ecotourism can greatly reduce the risk of extinction by providing money for conservation and protecting important habitats. However, without careful management, tourism can be harmful, especially when combined with other threats like poaching and habitat loss. To understand whether ecotourism will help or harm a species, local conditions and species-specific factors must be taken into account.
