The butterfly reserves in Mexico and Texas are great examples of how ecotourism can protect fragile habitats. When communities see the value in preserving these places, both economically and culturally, it gives them a stronger reason to fight against illegal activities like logging or land development.
Another place that comes to mind is Costa Rica. The country is known for its strong focus on ecotourism, and protecting rainforests and biodiversity is a huge part of their tourism model. Visiting national parks there directly supports conservation efforts and local economies. Their model is proof that a country can prioritize environmental sustainability while still benefiting from tourism.
