What does 'ecotourism' focus on?

Ecotourism is centered on responsible travel to natural areas and emphasizes the conservation of the environment and the well-being of local communities. This form of tourism aims to minimize the ecological impact while promoting sustainability and education about the natural environment. Travelers participating in ecotourism are typically more mindful of their impact and seek to engage in activities that support environmental preservation and cultural understanding.

The other options do not capture the essence of ecotourism. Luxury travel experiences often prioritize comfort and extravagance over environmental considerations. Tourism centered on historical sites focuses more on cultural heritage rather than ecological impact or natural conservation. Urban exploration does not align with the principles of ecotourism, as it typically involves city tourism rather than engagement with natural ecosystems. Thus, option C accurately represents the core focus of ecotourism.
