In this podcast episode, the host speaks with the founder and director of the Global Water Policy Project, Sandra Postel, and Georgetown geography professor Mark Giordano, to learn about solutions for conserving water and protecting the water cycle.
Students will learn about the water cycle and how climate change and uneven human consumption have caused many regions to experience water scarcity.
Students will also learn that agriculture and textiles use a tremendous amount of water, with agriculture using the most water by far.
This podcast episode will help foster the understanding that water is a shared resource.
A full transcript of the podcast episode is available.
The show notes provide links to sources for further reading.

Science and Engineering
ESS2: Earth’s Systems
MS-ESS2-4 Develop a model to describe the cycling of water through Earth’s systems driven by energy from the sun and the force of gravity.
ESS3: Earth and Human Activity
MS-ESS3-2 Analyze and interpret data on natural hazards to forecast future catastrophic events and inform the development of technologies to mitigate their effects.
MS-ESS3-3 Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment.
MS-ESS3-4 Construct an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impact Earth’s systems.
HS-ESS3-1 Construct an explanation based on evidence for how the availability of natural resources, occurrence of natural hazards, and changes in climate have influenced human activity.
Civics & Government
Civics & Government 1 (D2): Students understand the basic ideals, purposes, principles, structures, and processes of constitutional government in Maine and the United States as well as examples of other forms of government in the world by comparing how laws are made in Maine and at the federal level in the United States.
Geography 2 (F2): Students understand geographic aspects of unity and diversity in Maine, the United States, and the world, including Maine Native American communities, by summarizing and interpreting the relationship between geographic features and cultures of Maine Native Americans, and historical and recent immigrant groups in Maine, the United States, and the world.
