A central aspect of environmental science is to understand global impact of local and regional human activities. Humans can mitigate their impact through sustainable use of resources. Human activities can cause ozone depletion in the stratosphere and increases in the greenhouse gases in the atmosphere. Increases in greenhouse gases can cause human health and environmental problems. These environmental problems include global climate change, ocean warming, and endangered species. In this final unit, the goal is for you to describe and explain global changes in the environment, the causes of these changes and their consequences.
