Faced with alarming ecological forecasts related to Western lifestyles, this dissertation examines our relationship with the environment. It questions the complex dynamics between land management and nature conservation, seeking to determine whether national parks are genuine ecological solutions or instruments of territorial control. It explores the impact of colonialism and other cultural factors, such as naturalism, on biodiversity. It highlights divergences between Western and indigenous practices. It calls for an urgent rethink of our interaction with the environment, taking inspiration from the respectful and integrated approaches of indigenous cultures.
