ABSTRACT
Local, regional, and global environmental issues are inextricably linked and affect sustainable development. Therefore, there are synergistic opportunities to develop more effective response options to these environmental issues that enhance benefits, reduce costs, and more sustainably meet human needs. Freshwater is essential for food supplies, sanitation and human health. The near-surface ozone air pollution and the emissions that drive it are important contributors to global climate change. There are also a number of links between climate change and stratospheric ozone depletion. Changes in land-based and marine plant and animal systems occur for many reasons, including land-use change, pollution, climate change and increasing atmospheric concentrations of carbon dioxide. Climate change policy also needs to be linked to broader social and political issues such as equity. The numerous connections between climate change and other issues inevitably mean that there are ways in which action on any one issue may have an effect on another.
