Final answer:
Tourism in tropical rainforests can have both positive and negative impacts. It can promote ecosystem conservation through practices like ecotourism, protecting these precious ecosystems. However, it can also contribute to habitat destruction, particularly through deforestation.
Step-by-step explanation:
Two impacts of tourism on the tropical rainforest ecosystem are 1) ecosystem conservation and 2) habitat destruction.
Ecosystem conservation: Tourism, if well managed, can promote ecosystem conservation through practices like ecotourism. Ecotourism helps protect endangered rainforests and other important ecosystems, contributing to biodiversity conservation. For example, ecotourism in Tanzania's Ngorongoro Crater plays a powerful role in biodiversity conservation in tropical regions.
Habitat destruction: On the other hand, tourism can also contribute to habitat destruction, especially through deforestation. Forests provide habitat for diverse organisms, and the destruction of rainforest habitats through deforestation can lead to the loss of wildlife and vegetation, as well as the acceleration of endangered species' extinction.
