Renewable resources are considerered better for the enviorment because
A. They are less expensive to harness.
B. Once they are harnessed, they can be replaced.
C. They do not cause any pollution.
D. Using renewable resources encourages people to plant more trees.
Is the answer B?
Thank you
You're right.
Yes, the answer is B. Renewable resources are considered better for the environment because, once they are harnessed, they can be replaced. However, it is important to note that renewable resources can vary in terms of their environmental impact depending on how they are harnessed or utilized.
To arrive at the correct answer, you can eliminate the other options:
A. They are less expensive to harness: This statement is not necessarily true for all renewable resources. While some renewable resources may have lower operational costs than non-renewable resources, the cost of harnessing and utilizing renewable resources can also vary based on factors such as technology, infrastructure, and location.
C. They do not cause any pollution: While it is generally true that renewable resources cause less pollution compared to non-renewable resources, some forms of renewable energy production can still have an environmental impact. For example, wind turbines may pose risks to wildlife, and large-scale hydropower can have negative effects on ecosystems and fish populations.
D. Using renewable resources encourages people to plant more trees: Although planting trees can help mitigate climate change and support biodiversity, it is not directly related to the concept of renewable resources. Planting trees falls under the category of afforestation or reforestation, whereas renewable resources refer to sources of energy that can be replenished or regenerated naturally, such as solar, wind, hydro, and biomass.
Hence, the correct answer is B, as renewable resources can be replaced once they are harnessed, making them a more sustainable option for energy production.
