Question 1Holistic Environment (5): The environment as a whole. Not just that around you- but
that which is all around everyone. Global Environment- the effects chopping down a
rainforest will have on the rest of the world, Physical environment – that which is immediately
around us, Cultural environment – what your culture is as does to influence the world,
internal environment – what WE feel and think, political environment- ideology, freedom and
equality, and social environment- how people relate to one another. Destroy one of these,
and we will have no future, as this is what we strive and live on. Page 35

positive attitudes towards the environment. It is concerned with actions taken or skills
learned to prevent environmental problems. The International Union for the Conservation of
Natural Resources definition reads “Environmental education is a process during which
values are discovered and concepts explained in order to develop skills and attitudes
pertaining to an appreciation of the relationship between man, his culture and his biophysical
environment. Environmental education also includes the practice of decision making and the
formulation of a personal code of conduct on matters affecting the quality of the
environment.” – environmental education- values and concepts which are taught and
explained in order for everyone to understand the importance of the environment, and how
to keep their environment safe and clean. Page 39

and the ecological communities they inhabit More than 1.4 million different species have
been discovered on planet earth. SA has the third highest level on diversity in the world.
Many species are disappearing as a result of *loss of habitat *pollution of soil, water and air *
