The key principles of sustainable development include intergenerational equity, environmental integrity, social inclusion, and economic viability. Intergenerational equity emphasizes the responsibility to manage resources wisely so that future generations can enjoy the same benefits as the current population. Environmental integrity focuses on maintaining the health of ecosystems and biodiversity, recognizing that a healthy environment is essential for human well-being. Social inclusion ensures that all members of society have a voice in decision-making processes and access to resources, while economic viability promotes sustainable economic growth that does not harm the environment or society.
