The correct answer is reducing waste or harm to resources.
The correct response that describes conservation of resources is "reducing waste or harm to resources". This means minimizing the depletion or degradation of natural resources by taking actions such as reducing consumption, reusing materials, recycling, and implementing sustainable practices. Conserving resources helps ensure their availability for future generations and minimizes environmental impact. To arrive at this answer, you can eliminate the other options since they either go against conservation efforts (increasing resource use) or are unrelated (finding more sources of fossil fuels and replacing unlimited energy sources).
