How can the problem of air pollution be solved? People should try to use alternative source of energy, such as solar, water and wind energies. There are more ways to reduce air pollution caused by road traffic. First it is possible to switch freight from road to railways and to support public transport. Another way is to encourage tree planting, because trees absorb carbon dioxide. Then all new petrol-driven cars will have to be fitted with three-way catalytic converters in their exhaust system which turn dangerous gases into CO2, nitrogen and water vapour. Lead emissions can fall if we reduce lead content in petrol and encourage the use of unleaded petrol. People should burn smokeless fuels. End-of pipe system can be installed to clean up emissions.
