The world is facing an uphill battle to reduce air pollution which has led to a series of health
hazards.In my opinion,the real solution to air pollution is to replace fossil fuels with clean
energy like solar and wind energy.Firstly,by utilizing the sun and the wind to produce clean energy,
pollution from dirty energy such as fossil fuels can be greatly reduced.The overuse of fossil fuels
such as coal has given rise to the emission of pollutants like nitrogen oxides and carbon dioxide
which are looming as one major threat to air quality.According to the offical statistics,carbon
dioxide emission reached 18.57 million tons in 1999,posing a serious threat to air quality.Therefore
,harnessing solar and wind energy can effectively reduce pollutants emission from fossil fuels and
significantly improve air quality.Secondly,renewable forms of energy such as solar and wind energy
are non polluting and environmnetally friendly.It is widely acknowledged that solar and wind energy
are clean,free and inexhaustible.They provide energy for cooking,lighting,heating and cooling
without any direct emissions.In conclusion,to win the battle against air pollution,some urgent
measures have to be carried out immediately.Replacing fossil fuels with sustainable clean energy
is the top priority.
