Introduction
In the last hundred years, we have done
great damage to the environment, and
until the last ten years or so, we havent
cared or thought about theconsequences. Nowadays, a lot of
countries have finally begun to take
action and consider the environmental
issues we are facing.
Like the rest of the world, Australia has
its share of the environmental problems.The main problems are deforestation
and pollution.

DeforestationDeforestation
Deforestation is cutting, burning anddestroyingtrees andforests
This has become a causeforotherenvironmentalproblems likeclimatechange, airpollution andloss of animals andplantation.
Deforestationhas become a problem, because itreduces the amountofoxygen inthe airforushumans to breathe.
Itcan alsoleadtothedestructionofnatural
habitats, causing animals andplants to becomeendangeredorextinct
Medicine is found intropicalplants, andAustralia is hometoone millionofthese species
Here are somecauses fordeforestation:

This graph compares the amount of land clearing to the re-growth of trees in Australia fromthe year 1973 to 2004.
As you can see, the amount of land clearing is much larger than the amount of trees beingre-grown, and so we are losing trees every year. However, the net change is getting smaller
and smaller so we are getting close to re-growing the amount of trees lost in that year.

AirPollution
Urban and regional air pollutionis a significant environmentalthreat. Industry, power generationand motor vehicles release
pollutants that can lead tophotochemical smog, haze andacidification.

LandPollution
Land pollution can be
caused by poor agricultural
practices, pesticide use,
mineral exploitation,industrial discharges and
indiscriminate disposal of
urban waste.

WaterPollution
Poor water quaility and sediment quaility
are the most serious pollution issues
affecting our coastal and marine
environments.
In Australia, it has been estimated thatland-based contaminants contribute up to
80% of all marine pollution, and pose amajor threat to the long-term health of
coastal waterways.

Conclusion
If we want to hand on our world to
our children and grandchildren, we
simply cant continue to misuse the
worlds natural resources and keep
polluting our Earth as we are at themoment. We need to do something
while we still can. All big things are
made of smaller things, so by you
making a small change to help our
world change, things will spread to
make a big difference.
