As we know, our health is closely connected with the degree of air pollution. Our air has become polluted and it is high time we took action to slow down the air pollution. First of all, practical measures should be taken to stop some factories from giving off waste gases. Those gases are sometimes poisonous and greatly pollute our atmosphere. Secondly, se should plant as many trees as possible. Trees can clean up the air, supply fresh air to us and help improve the natural environment. Finally, drive fuel-efficient cars. If possible, walk or bicycle to save energy and use new energy to produce less or no pollution to the atmosphere. If we do our best to protect our environment from now on, there is still hope for us to enjoy blue sky and breathe clean air every day.
