According to the International Ecotourism Society, ecotourism is defined as travel that is:

The definition of ecotourism according to the International Ecotourism Society emphasizes responsible travel that benefits natural areas and promotes environmental conservation. This approach is rooted in the idea of preserving the integrity of ecosystems while providing travelers with an opportunity to experience and appreciate nature. The focus on responsibility signifies that ecotourism should not only minimize the negative impact of tourism on the environment but also actively contribute to the protection and sustainable management of natural resources.

Moreover, this definition aligns with the principles of sustainability, encouraging travelers to engage with local cultures and ecosystems in a way that enhances both their experience and the well-being of the destinations they visit. Therefore, ecotourism is not just about visiting beautiful places but also ensuring that such areas are preserved for future generations while fostering respect for the environment.

In contrast, other options do not capture the essence of ecotourism. For instance, a focus on luxury and leisure does not align with responsible tourism practices, and centering on technological advancements in travel does not inherently involve environmental concerns or local community engagement. Similarly, while educational purposes can be a component of ecotourism, defining it as exclusively for educational purposes overlooks the broader responsibility towards natural areas and conservation efforts.
