Why are we overfishing the oceans? Why are we cutting trees faster than they're growing? Why did the Easter Islanders resort to cannibalism? And how did an economics professor dad stop his teenage sons from wasting his whole paycheck on soda pop? It turns out that all of these are examples of the Tragedy of the Commons. This economic theory explains why, when a resource is collectively owned, there is no incentive to use it sustainably. This explains why many natural resources are depleted, even though that makes everyone worse off.

This half-semester course studies the economics of the principal markets related to marine transportation, environment, and natural resources. Topics include structures of the markets and industries involved; competition; impacts of policies and regulations. The course analyzes the relationship among industries, markets, technologies, and national policies, and introduces the concepts of national income accounts, sustainability, and intergenerational equity and their relationship to current economic practice.

In this media-rich lesson, students learn how global warming is changing the Alaskan environment and examine the consequences of climate change on the region's human and wildlife inhabitants.

The northern reaches of the planet are melting at a pace few nations can afford to ignore, yielding potentially lucrative returns in energy, minerals, and shipping. But debate is mounting over whether the Arctic can be developed sustainably and peaceably.

With increasing public awareness of the multiple effects of global environmental change, the terms water, energy, and food crisis have become widely used in scientific and political debates on sustainable development and environmental policy. Although each of these crises has distinct drivers and consequences, providing sustainable supplies of water, energy, and food are deeply interrelated challenges and require a profound understanding of the political, socioeconomic, and cultural factors that have historically shaped these interrelations at a local and global scale.

This issue of the free online magazine, Beyond Penguins and Polar Bears, explores the Sun's role in warming Earth, the albedo (reflectivity) of Earth's diverse surfaces, and how the decline of Arctic sea ice is affecting Earth's energy balance. Science lessons introduce the concepts of solar energy, reflection, and absorption to elementary students. The issue also includes an overview of the natural resources and energy sources found in the polar regions as well as lessons that allow students to develop the concepts of natural resources, energy sources, and energy efficiency.

This collection uses primary sources to environmental preservation in the Progressive Era. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.

Course combines the fields of ecology and conservation with planning for the efficient use and preservation of land, water, wildlife, and forests. Within this course may be topics covering environmental factors affecting water, water pollution, water and land use management, alternative energy resources, metals and minerals.

This is a compilation of resources from the Nebraska Ethanol Board, including reviewing the economic and environmental benefits of ethanol.  All resources are produced by the Nebraska Ethanol Board.  https://ethanol.nebraska.gov/

In this video from Common Ground and Cleaner Water, Tribby Vice, a Kentucky farmer, talks about the changes he has made on his farm to protect the water quality of the stream running through his property and the watershed in which he lives.

In this adaptation of a video that high school students created in collaboration with the Environmental Justice League of Rhode Island, learn what's whack about our current food systems and the many actions individuals can take to address these issues.

Students will explore the components of soil and make a model of sedimentary rock layers and fossil fuels.

Geysers and grizzlies and glaciers, oh my. The national parks may be America's best idea, saving the finest parts of the nation for everyone to enjoy forever. What better way to learn about the natural world than to tour the parks with us? We'll explore how the mountains and valleys formed and why they often come with volcanoes and earthquakes. You'll see what really killed the dinosaurs and how we can help save their modern relatives in the parks. With film clips, slide shows, and our geological interpretations of classic rock songs, isn't it time for a road trip?

Students listen to the book The Goat in the Rug, about a Navajo weaver who uses a number of resources and intermediate goods to make a traditional Navajo rug. The students are placed in groups to learn about productive resources and intermediate goods. They play a matching game and make posters to classify the natural resources, human resources, capital resources and intermediate goods used in the story.

This video segment adapted from NOVA explores the effects of the Glen Canyon Dam on the beaches, wildlife, and vegetation of the Colorado River.

In this video adapted from Bullfrog Films, GwichŰ__Ű__ŒŒÇin Chief Evon Peter of Arctic Village, Alaska, describes his people's connection to the caribou and their passion to protect Alaska Native land and traditions.

In this lesson, students listen to a story about a little girl who wants to make an apple pie. When she finds the market closed, she travels around the world gathering natural resources to make the pie. Students will follow along with the story by connecting each natural resource to its country of origin and pointing out those places on a globe or world map. They will also identify the capital goods used to transform the natural resources into ingredients by examining the pictures from the book. Students will take part in two rounds of a trading activity, collecting the ingredients required for vanilla ice cream to go along with the apple pie. They will learn about trade and how middlemen, such as grocery stores, help make trade easier.

Students will explore trees in their outdoor classroom, learn about the important functions that trees serve and devise ways to conserve trees by changing human behaviors: recycling, etc.

Learn where diamonds originate and how inclusions trapped within diamonds help geologists determine their age in this video segment from Nature.
