3. The wise and economic use of natural resources for development is
essential to carry out nature friendly development.

4. Sustainable development does not undermine the integrity, stability and
beauty of various components of natural environment.

5. Sustainabledevelopmentisonlythewayofconservingvariouscomponents
of natural environment. It helps in maintaining environmental balance
with the wise and judicious use of natural resources.

6. Unwise and excessive use of natural resources for industrial purpose
degrade environment and by products of industries or factories pollute
environment.

7. People environment and development are inseparable and there is close
interrelationship between these aspects.

8. Sustainable development is necessary for the betterment of human
beings. Thus, it is the responsibility of human beings to conserve nature.

9. Public awareness is necessary to make the people aware about the
importance of environment and necessity of sustainable development.
