The components of environmental science are geosciences, atmospheric sciences, ecology and environmental chemistry. Geosciences are further subdivided into environmental geology, environmental soil science, volcanic phenomena and evolution of the Earth's crust. There are other areas of study which are closely related to environmental science such as environmental engineering. The environmental issues studied under this field include pollution control, climate change and its effects as well as alternative energy. Some of the diverse topics covered in this book address the varied branches that fall under the category of environmental sciences. It will also provide stimulating topics for research which interested readers can take up. The extensive content of this book provides the readers with a thorough understanding of the subject.
