I refer to the letter from Eric Jim regarding the air quality of Hong Kong (South China Morning Post, July 22).
Air pollution is the outcome of industrialisation, since air pollutants are mainly emitted from the combustion of fossil fuels in industrial plants, power stations, incinerators and cars.
On the one hand, industrialisation raises our living standards, but on the other hand, it also adversely affects our living standards.
I agree with Eric Jim that the air quality in Hong Kong is deteriorating at an astonishing rate. If there are no improvements, this could have disastrous consequences for people's health.
As Mr Jim said, we will suffer from various kinds of respiratory diseases if the situation does not improve.
The earth's atmosphere will also be affected. The carbon dioxide concentration increases, as a result of industrial activities. More infra-red radiation from the earth is trapped, resulting in an increase of air temperature.
Though it is impossible to eliminate air pollution altogether, we should not just leave it to governments.
We can all play our part to improve air quality, since we all live in the world. How can we tolerate living on a planet where the temperature is steadily rising? JOCELYN CHAN Tsing Yi
