Man lives in a society on which he is largely dependent and to which his contribution matters. Man cannot make his living all by himself. He has to depend on others for many things. Usually many works have to be done by several persons collectively. Constructions of buildings, running an institution, organizing a community function or meeting requires the work and help of many individuals. These can be successful only if everyone corporate with others. Team work requires co-operation of all the members of the team. Their sayings are “Unity is strength”, “Pulling together can move mountains” a bundle of sticks cannot be easily broken as it is, but individual sticks can be broken easily. Thus the co-operation in any work adds strengths and leads to success. Man must learn to cooperate with others. It gives not only the strengths and success in completing a work, but also a peace of mind and happiness in contributing the pleasures confusions, inadequacy, and fear of failure.

The environmental movement has led to an increased awareness among people that they have a responsibility to use their knowledge and skills to help protect the environmental. It helps to provide the ethical roots of the environmental movement and to understand the responsibility of the environmental. The western ethical tradition is anthropocentric which gives important of plants and animals to humans. This is often evident even within the environmental movement when plants are protected based on their potential for providing new medicines. In cost-oblivious approach, cost is not taken into account but rather the environment is made as clean as possible. This approach bears a striking resemblance to rights and duty ethics. The next approach is cost-benefit analysis which derived from utilitarianism. So we can analyze the problems in terms of the benefits derived by reducing the pollution. In this approach, the goal is not to achieve a completely clean environment and to determine the optimum combination.
