3. ENVIRONMENTAL EDUCATION
Man, as a part and parcel
of the environment, has to
recognize the role and
importance of environment
in order to protect it and to
get protection from it, for
this, he needs
environmental education.

5. MEANING
Environmental Education, which is
relatively new, is an interdisciplinary
process that aims at equipping
people with the knowledge,
attitudes, skills and motivation that
they need to help resolve
environmental issues.

6. NEED FOR THE
ENVIRONMENTAL EDUCATION
•Some form of environmental pollution affects
each and every nation though the issues differ
•Some of the most urgent environmental threats
to be dealt with now and in the future
•Educational institutions all over the world have
been making intense efforts to meet the
challenges arising from politics, science and
public opinion towards integrating
environmental concerns

7. Programmewith the following aspects:
