How are humans changing the environment and particular ecosystems? The USGS has done a great job in providing three studies of current situations where the delicate balance of nature and mankind is tipping. Students will study three cases: mudslides in Los Angeles, damage to the Everglades, and possible contamination of ground water in Cape Cod. Each case presents a Focus Question that allows students to devise a plan towards a possible solution. These are excellent case studies relevant to the theme of "How people change the environment" -- a theme prevalent in many state standards.
