Pollution is one of the biggest problems in 
the world today.
We should try our best to protect the 
environment.
Coal, oil and natural gas are not only useful 
for families, but have a wider use for 
factories.
If we do not act to improve the environment,
more living things will be killed by pollution.

Follow these small steps, and you can make
a big difference to the Earth!
Recycling is also a good way to help 
reduce pollution.
