How can light pollution be reduced?
The government has acted on the problem of air and land pollution, but we cannot see what it has done to tackle light pollution. It should be more concerned about light pollution because the problem is not only related to residents who are affected, it is connected to wasted energy. The government should set up a law that advertising boards in residential areas are switched off before 10pm, otherwise the owner will be punished.
Offering HK$200 coupons is a good idea to encourage people to use energy-saving bulbs. However, it is better for the government to set up recycling points for people to exchange energy-saving light bulbs. People can dump light bulbs easily and the government can also collect them conveniently and send them to the chemical and hazardous waste treatment centre in Tsing Yi, avoiding the risk of releasing mercury from broken fluorescent bulbs.

As the population rises, the number of houses, buildings, factories and shopping malls does too. This infrastructure needs electricity, and light pollution can be as serious as carbon dioxide emissions.
The air we breathe and our quality of life will be affected by the generation of electricity, which emits greenhouse gases. What is very upsetting is that most of the light is unnecessary and wasted.
As long as we live on Earth, we have an obligation to protect our environment. Each person should turn off all unnecessary lights in the home. Families and schools need to educate the next generation about light pollution.
