Which is an example of a sustainable practice?
I. Replanting a logged forest
II. Developing substitutes for nonrenewable resources
III. Banning the use of all fossil fuels A) I only B) II only C) I and III D) I and II E) I, II, and III
The Correct Answer and Explanation is:
The correct answer is D) I and II.
Explanation:
Sustainability refers to practices that ensure that resources are used in a way that does not deplete or permanently damage them, allowing them to be available for future generations. Let’s evaluate each option:
I. Replanting a logged forest
Replanting a logged forest is an example of a sustainable practice because it helps restore the ecosystem after it has been disturbed by logging. Reforestation allows for the replenishment of trees, which are vital for absorbing carbon dioxide, providing oxygen, maintaining biodiversity, and protecting soil from erosion. Sustainable forestry involves harvesting timber in ways that allow for regrowth, ensuring the forest’s long-term viability. By replanting trees after logging, the balance of the ecosystem is maintained, and it becomes a renewable resource, which is key to sustainability.
II. Developing substitutes for nonrenewable resources
Developing substitutes for nonrenewable resources is another example of sustainability. Nonrenewable resources, such as fossil fuels (coal, oil, and natural gas), are finite and their extraction can harm the environment. By researching and developing alternative energy sources (like solar, wind, or hydroelectric power), materials that are renewable, or more sustainable forms of manufacturing, we can reduce dependence on nonrenewable resources and minimize environmental damage. This is crucial for creating a sustainable future because it helps reduce resource depletion and pollution.
III. Banning the use of all fossil fuels
While reducing fossil fuel use is important for sustainability, a total ban on all fossil fuels is not a practical or sustainable solution in the short term. Fossil fuels are deeply integrated into modern society, powering transportation, industry, and electricity generation. A complete ban would have significant social and economic impacts, potentially leading to energy shortages. Instead, a more sustainable approach would involve transitioning to renewable energy sources over time while improving energy efficiency and reducing carbon emissions.
Conclusion:
Replanting forests and developing alternatives to nonrenewable resources both support sustainability, while banning all fossil fuels is a more extreme and less practical solution. Therefore, the correct answer is D) I and II.
