Sustainable development is defined as meeting present needs without compromising future generations, addressing global challenges like poverty and climate change through economic, social, and environmental sustainability. The United Nations' 17 Sustainable Development Goals (SDGs) emphasize targets such as no poverty, quality education, and climate action while facing challenges like climate change and resource scarcity. The document highlights the roles of individuals, governments, and organizations in promoting sustainability, as well as the importance of innovation and collective global efforts for a prosperous future.
