Effects of Air Pollution

• Affect the tourism• Get respiratory disea

ses easily• Acid rain - Vegetation

- Aquatic life- Building materials

Effects of Air Pollution

• Greenhouse effect– Rise of sea-level– Changing rainfall patterns– Increase in agriculture production

Methods of solving air pollution

• Use public transports instead of private vehicles

• Set laws to restrict the amount of exhaust fumes from the vehicles

• These can reduce the exhaust gas produced by the vehicles,thus less pollutants will be formed.

A public transport-bus

• To reduce the number of waste incineration since this produces lots of pollutants

• To avoid the burning of fossil fuels as they contain a lot of polluting gases

• Avoid smoking in the public area in order to reduce the amount of toxic gases. Smoking produces lots of harmful gases.

• Set laws to control the amount of exhaust fumes produced by power stations and factories

Suggestions to the HKSAR

• Provide financial support to car owners for car maintenance regularly.

• Plant more trees along the road side.

Suggestions to the HKSAR

• Develop alternative power resource to reduce the dependence on fossil fuels.
