Increased attention to how human activity affects our external world, particularly in a negative way, has meant that the protection of environmental values has become a political issue. Human activity affects nature in many different ways and therefore environmental protection encompasses many different aspects.

Examples of environmental protection issues are the conservation of natural areas, protection of endangered species, reduction of emissions of environmental toxins, countermeasures against littering, and reduction of air emissions that contribute to changes in climate. the atmosphere, including the protection of the ozone layer.

This book is a manual to understand the problems surrounding the Environment, and how they can be faced with practical measures from homes, through local governments to international agreements.
