A two-day assignment focusing in the melting or Arctic sea ice and the increased global temperature. The lesson involves reading the text Decline in Arctic Sea Ice, reviewing video clips, in depth discussions, and independent research and writing.

This course provides a review of physical, chemical, ecological, and economic principles used to examine interactions between humans and the natural environment. Mass balance concepts are applied to ecology, chemical kinetics, hydrology, and transportation; energy balance concepts are applied to building design, ecology, and climate change; and economic and life cycle concepts are applied to resource evaluation and engineering design. Numerical models are used to integrate concepts and to assess environmental impacts of human activities. Problem sets involve development of MATLAB® models for particular engineering applications. Some experience with computer programming is helpful but not essential.

This video segment adapted from the NOW-RAMP 2002 Expedition documents a research expedition to Pearl and Hermes Atoll in Hawai`i. Watch as biologists assess the bird and plant populations and then work to eradicate invasive species.

In this video from Outdoor Nevada, Brian Wignall speaks with an ornithologist about the peregrine falcon, a majestic and endangered species that is one of the fastest animals in the world.

In this video adapted from Texas Parks and Wildlife Department, learn about the prairie dog, the importance of its role in its ecosystem, and how it is affected by an ever-growing human population.

Examine how the human/grizzly relationship has changed since the closing of the Yellowstone dumps, and also learn about the challenges posed to both humans and bears, in this video segment from Nature.
