Final answer:
Resources like Global Giving and OpenStax provide insights and examples on understanding and dealing with sustainable development and resource scarcity.
Step-by-step explanation:
Understanding the Sustainable Development Goals (SDGs) is crucial for addressing global challenges. Two valuable resources for this purpose include the Global Giving website, which offers insight into development of small-scale economic initiatives with sustainable resource use, and the OpenStax website discussing the United States' approach to resource scarcity such as droughts. By examining economic indicators such as the Gross Enrollment Ratio, Education for All, Millennium Development Goals (MDGs), and Universal Primary Education (UPE), one can gain a comprehensive understanding of the factors influencing sustainable development.
