Sustainability is the practice of meeting the needs of the present without compromising the ability of future generations to meet their own needs, balancing environmental, economic, and social equity. It focuses on living within the means of natural resources by reducing pollution, conserving ecosystems, and promoting renewable energy to ensure long-term, productive harmony between humanity and nature. 

Three Pillars: The core of sustainability rests on three pillars: environmental (protecting nature), social (ensuring equity and health), and economic (responsible, long-term growth).

Key Practices: Achieving sustainability involves adopting the 4 R's (refuse, reduce, reuse, recycle), using public transportation, and switching to renewable energy to minimize carbon footprints.

Goal: The ultimate goal is to maintain a, healthy planet, preventing the depletion of resources so that they remain available for the long term. 

By implementing sustainable practices, we reduce pollution and protect biodiversity, creating a better, more stable quality of life for all.
