The deteriorating earth's environment is a matter of concern for all. Though the leaders of different countries are trying to face the situation at a greater level, but every individual can contribute in this regard. We use different things in our house or office. These are derived from plant, animal or mineral products (the natural resources). Less we use them, less is the demand on natural resources. We can help to protect the environment while acquiring, while using and while disposing them off. We should acquire that much of things which is exactly required for us (acquisition). Once acquired, we should take their proper care so that they remain useful for a long time (maintenance). And once an article is damaged, we should judiciously dispose it off (disposal). If we become careful at all these three stages of dealing with our material things, we can reduce the demand on their production. Reduced production means preservation of natural resources; hence the environment. Then only the earth can be saved. Co-operation of every individual is essential. Details about these three steps are described in this book.
