Which best defines sustainable development?

The definition of sustainable development focuses on achieving a balance between meeting current needs and ensuring that future generations can also meet their needs. This approach encompasses economic growth, environmental preservation, and social equity, recognizing that these elements must work together harmoniously.

Option B captures the essence of this balance by emphasizing the importance of not compromising the resources and opportunities available to future generations. This involves thoughtful stewardship of natural resources, equitable distribution of wealth, and strategies that promote long-term ecological health alongside economic progress.

The other options don't align with the principles of sustainable development. For instance, merely maximizing immediate economic growth overlooks the long-term consequences on the environment and social structures. Preserving all natural habitats without regard for human needs would ignore the necessity of finding a workable balance between conservation and human activity. Lastly, using resources exclusively for technological advancements may lead to progress in one area but fail to address broader environmental and social impacts for future sustainability. Thus, the answer reflects a comprehensive understanding of responsible development that benefits both present and future generations.
