SAVE THE EARTHOur
planet has a natural environment, known as ‘ecosystem’, which includes
all humans, animals, plants, land and water. Human activities have
caused much depletion and destruction of this ecosystem.
Environmentalism advocates the preservation, restoration and/or
improvement of this natural environment by controlling pollution and
protecting plant and animal diversity. Environmentalists attempt to
balance relations between humans and the various natural systems on
which they depend to achieve sustainability.
