This book has been designed as a text book for students. Therefore, every effort has been made to make the subject matter very simple. Due to the importance of environmental education, it has been made compulsory in various competitive examinations. Today it is very important to be sensitive towards the deteriorating environment because the happiness and peace of our human race remains. Environment is defined as the total planetary heritage and the totality of all resources. It includes all organic and inorganic factors which affect each other. All living elements like birds, animals, plants, forests, fisheries etc. are organic elements whereas inorganic elements include air, water, land etc. Rocks and sunlight are examples of inorganic elements of the environment. Environmental studies need to study the interrelationships between these organic and inorganic components of the environment. The environment performs four important functions. It provides resources. The resources here include renewable and non-renewable resources. Renewable resources are those resources that can be used without the resources being exhausted or likely to be exhausted. That is, there is a constant supply of resources. Examples of renewable resources are forest plants and marine fish. On the other hand, non-renewable resources are those which get exhausted by digging and use. Environment is becoming a matter of concern for everyone today. The way we are exploiting the environment today, its impact is to be faced by us or our descendants in the coming days. You are seeing that somewhere there is a flood and somewhere there has been a drought. Today we are making full use of coal, wood etc. Never do we think how long it took for coal to be made. Will it be saved for the next generation or not? It needs to be saved for the future. Will be saved only when you use another resource of energy. How will you know about the second resource when you read a book related to the environment. In this book, all the measures to save natural resources have been told. This book is not limited to students, it can also be useful for those people who are knowingly or unknowingly dissolving the pollutants from their factories, vehicles and sound equipment in the environment and are blaming nature when they face difficulties. Nature is an object of enjoyment for them. This book can also benefit the distinguished people who are environmental reformers for the society.
