Nowadays,
almost everyone drives a car to arrive at work. We also use electricity to
power almost everything in our lives: fridges, computers, cell phones, and a
whole lot more.
“But this electricity has to come from some place,” you may think, and indeed,
the electricity you consume is most often generated through the stoking of
fossil fuels such as oil, natural gas and coals. We also burn fossil fuels in
factories to create other products. But oil, gas and coals aren’t the only
source of energy we’ve got: nuclear power plants generate electricity through
allowing radioactive materials to react with each other under tightly regulated
conditions. Aside from these sources of energy, there are also several sources
of energy which generate power which is considered ‘green’ and ‘clean’ – wind,
solar and bio-fuel are amongst them.
But even
though more ‘green’ sources of energy are becoming available, most of our
electricity is still being generated by fossil fuel plants and nuclear
reactors. Even then, air pollution is not solely caused by the burning of fuel.
And while we know there are certain health risks involved, we often choose to
turn a blind eye to them…
