As the world's
population increases, many changes will be necessary. These changes are needed
not only in our societies. In order to sustain a growing population, we must
also make changes in the way we manage our most precious asset - the earth.
One change we
must make is the way we use earth's resources. More people on earth will mean
more mouths to feed. This is especially critical in third world countries where
starvation is a real threat to survival. In these areas, land must be conserved
so that there is always enough fertile land for farming. This applies to water
as well. Clean, drinking water is essential for survival. We must also protect
areas with forests. Forests clean earth's air and are home to many types of
wildlife. Protecting and conserving earth's resources will be a big step to
sustaining a growing population.
With an
increasing population, there will also be more pollution. We must do all we can
to fight this pollution, especially in urban areas. We must encourage people to
drive electric or hybrid cars to reduce greenhouse gases. Also, everyone must
do their part to recycle their waste. Recycling will help to keep earth clean
and decrease the manufacturing of new products. By taking these steps in
reducing pollution, we will allow more people to live on the planet
comfortably.
Finally, we
must develop new sources of energy. Currently, our main source of energy comes
from oil that is brought up from the ground. This oil will soon dry up.
However, there are many other sources for energy. Energy can be collected from
the sun using solar panels. Wind can power engines to make electricity. Even
dams can be built to draw power from rivers. Developing these types of
alternative sources will ensure that we will never run out of energy.
The earth is
our home. And it is getting more crowded each passing day. Just like our family
homes, we must take steps to clean and protect it. By doing so, earth will be
able to support its growing family of people.
