need discussion for solution to global issues class

Discussion paper needed for solution to global issues class:

need a half page with at least one source, plagiarism free: 

Chapter 10, "Alternative Futures," in your textbook discusses how developed and developing countries that have access to the planet's resources (because they can buy those resources from others or because those resources exist in abundance in that country) continue to grow at a fast pace, placing a tremendous strain on the availability of nonrenewable resources.

• Briefly, what nonrenewable natural resources are most at risk of depletion?
• Discuss some sustainable development models that have broad applicability to the needs and consumption demands of both developing and developed countries.

Most students used only coal and fossil fuel as an example, I would like to add some other (maybe nuclear?) nonrenewable source as well.
