26. For an upcoming geography lesson, a third-grade teacher wants to use current events to show students examples of sustainable development. Which of the following provides the best example of sustainable development?
Answer: D
A landscaping company plants only trees and flowers that are indigenous to the region.
Using indigenous plants for landscaping is a prime example of sustainable development as it supports local ecosystems, conserves water, and promotes biodiversity. This approach minimizes the ecological footprint and encourages the preservation of native species.
A) A city builds a concrete barrier near a highway to prevent migrating wildlife from entering the roadway.
While this option aims to protect wildlife, building a concrete barrier can disrupt natural migration patterns and habitats. It does not promote sustainable development, as it may hinder ecological connectivity and could lead to further environmental issues.
B) A corporation builds an oil drilling platform one mile from the coast of a wildlife preserve.
This option poses a significant risk to the environment and contradicts the principles of sustainable development. Oil drilling has the potential to cause oil spills and pollution, which can severely impact the nearby wildlife preserve and compromise its ecological integrity.
C) A geologist warns state officials that a nearby volcano could erupt in the next decade.
Although this warning is important for safety and preparedness, it does not exemplify sustainable development. It focuses on disaster risk rather than proactive measures for maintaining environmental health and sustainability.
D) A landscaping company plants only trees and flowers that are indigenous to the region.
This choice exemplifies sustainable development as it involves using local plant species that are adapted to the environment. By doing so, it supports local wildlife, reduces the need for chemical fertilizers and irrigation, and enhances the overall health of the ecosystem.
Conclusion
The choice of planting indigenous trees and flowers demonstrates a commitment to preserving local ecosystems and promoting sustainability. In contrast, the other options either hinder ecological integrity or focus on immediate concerns rather than sustainable practices. Therefore, option D stands out as the best example of sustainable development in this context.
