Step 1: Context of "Limits to Growth"
Published in 1972, "Limits to Growth" examines global environmental and economic challenges arising from overpopulation, overconsumption, and resource depletion. The book utilized computer simulations to forecast global development, specifically addressing the unsustainable trajectory of population growth, industrial output, pollution, food production, and the exhaustion of nonrenewable resources.
Step 2: Analysis of Options
- (A) "Depletion of the Earth's resources" → This option is accurate. The book's core concern was the depletion of natural resources, such as fossil fuels and raw materials, due to unsustainable consumption patterns.
- (B) "Depletion of Ozone Layer" → While a significant environmental issue, ozone layer depletion was not the central theme of "Limits to Growth."
- (C) "Coastal Pollution" → Coastal pollution is an environmental concern but not the primary subject of the book.
- (D) "Water Pollution" → Water pollution is another environmental issue, but it is not the primary focus of "Limits to Growth."
Step 3: Conclusion
"Limits to Growth" primarily addresses the depletion of Earth's resources, making option (A) the correct selection.
