A sustainable society would emphasize:
A. maintaining the current rates of energy flow and resource use B. converting the world’s high-quality energy resources to low-quality heat C. recycling both matter and high-quality energy D. using energy efficiently and reusing and recycling matter E. quickly expanding nuclear power, because it is a renewable resource
The Correct Answer and Explanation is :
The correct answer is D. using energy efficiently and reusing and recycling matter.
A sustainable society aims to meet the needs of the present without compromising the ability of future generations to meet their own needs. This principle underscores the importance of efficiency and recycling in energy and resource use.
Using energy efficiently means implementing technologies and practices that reduce energy consumption while still achieving the same or greater levels of output. For example, energy-efficient appliances, improved insulation in buildings, and the use of renewable energy sources like solar and wind power all contribute to reducing overall energy demand. Efficiency not only lowers energy costs but also minimizes environmental impacts, as less energy consumption leads to fewer greenhouse gas emissions and reduced depletion of natural resources.
Reusing and recycling matter refers to the principles of the circular economy, where materials are kept in use for as long as possible. Recycling reduces the need for new raw materials, thus conserving natural resources and reducing waste. For example, recycling metals, plastics, and paper can significantly decrease the energy required to produce new products from virgin materials. Additionally, reusing materials can extend their lifecycle, further reducing waste.
In contrast, options A, B, C, and E do not align with the goals of sustainability. Maintaining current rates of energy flow and resource use (A) does not address the need for improvement; converting high-quality energy resources to low-quality heat (B) is wasteful; while recycling both matter and high-quality energy (C) is misleading as energy cannot be recycled in the same manner as matter. Lastly, while nuclear power (E) is often considered a low-carbon energy source, it is not classified as renewable due to the finite nature of uranium resources and the issues associated with nuclear waste disposal.
In conclusion, focusing on energy efficiency and material reuse and recycling is essential for building a sustainable society.
