The document discusses the relationship between the environment and sustainable economic development. It defines environment and explains how it is interdependent with development. Sustainable development is defined as meeting present needs without compromising future generations' ability to meet their own needs. While economic growth benefits standards of living, it has also degraded ecosystems. Maintaining balance requires policy interventions like promoting cleaner technologies, efficient resource use, and international cooperation. Development and environment impact each other, so sustainable development is needed.
