Ecotourism involves responsible travel to natural areas in a way that conserves the environment and benefits local communities. It aims to minimize impacts, build cultural awareness, provide positive experiences for visitors and hosts, and financially support conservation. Key principles include generating financial benefits locally, delivering interpretive experiences to raise environmental awareness, and recognizing indigenous rights. While ecotourism can support conservation and local development, some projects have negatively impacted communities through displacement, threats to culture, and environmental hazards like pollution if not properly managed.
