Join With us. The Multidisciplinary Nature of Environmental Studies. This course on the environment is unlike any other. It is not only a collection of facts or information about the environment. It is about the way we all should live. It is expected to give you information about the environment that will lead to a concern for your own environment. When you develop this concern, you will begin to act at your own level to protect the environment we all live in.

This is the objective of the course and the syllabus is a framework on which we must all realign our lives. This textbook deals with major environmental concerns that have been identified as important areas where background information is essential for a better understanding of our environment.

It stresses on a balanced view of issues that affect our daily lives. Unlike most other textbooks, it not only makes the reader better informed on these concerns, but is expected to lead him or her towards positive action to improve the environment.

There are three reasons for studying the state of the environment. Firstly is the need for information that clarifies modern environmental concepts such as the need to conserve biodiversity, the need to lead more sustainable lifestyles and the need to use resources more equitably. Secondly, there is a need to change the way in which we view our own environment by a practical approach based on observation and self learning.

Thirdly there is the need to create a concern for our environment that will trigger pro-environmental action, including activities we can do in our daily life to protect it. Environmental studies deals with every issue that affects an organism. It is essentially a multidisciplinary approach that brings about an appreciation of our natural world and human impacts on its integrity. This has led to many cultural prac- and philosophy.
