How does the definition of sustainable development underscore the concept of equity?

The definition of sustainable development highlights the importance of equity by emphasizing the necessity to meet the needs of both present and future generations. This approach acknowledges that the actions and decisions made today directly affect the resources and opportunities available for future populations. By striving for a balance between immediate human needs and the long-term health of the planet, sustainable development fosters a sense of responsibility towards ensuring that future generations inherit a world capable of supporting their needs. This notion inherently promotes equity, as it advocates for fair access to resources and opportunities across all populations and times, preventing the depletion of essential resources for those who come later.

The other options fall short of highlighting this integral balance. For example, focusing solely on maximizing wealth for current generations or ignoring future needs contradicts the principles of sustainability. Additionally, prioritizing environmental over social needs would neglect the social dimensions of sustainable development, which are crucial for achieving true equity.
