Fears grow for mainland food
Recently, the problem of tainted or fake foods on the mainland has been worsening. We are seeing fake eggs, tainted milk, chemicals in meat and cancer-causing substances in vegetables.
This problem has reached an alarming stage and the government must take action. Its job is to protect people's health and stop this happening. It needs to strengthen food safety monitoring and penalise people who produce poisonous food. If the government turns a blind eye to this problem, it will lose people's trust.
There's absolutely no reason to produce toxic foods. Even if people lack education, their conscience should never allow them to harm others.

Light pollution a huge problem in HK
We are all talking about how serious air and water pollution is, yet most Hongkongers ignore light pollution.
As tourism has developed, more and more shops are trying to grab buyers' attention with large neon advertising signs. This has not only caused complaints from residents and pedestrians, but also consumes a lot of energy.
Some advertisement boards in busy shopping centres, like Causeway Bay, turn the nights into days because shops keep all their lights on even when they are closed. This wastes a huge amount of energy and will increase global warming, both through the greenhouse gases produced during the process of electricity generation, and the extra heat from the lights.
Although there are campaigns like 'Earth Hour' to remind people to reduce light pollution and cut energy use, it is not enough. We need to act now and should start by turning off all unnecessary electrical appliances.

Better education brings better society
Recently, the government implemented a policy of cutting the number of classes in public secondary schools. I don't think this is a good long-term solution to the problem of falling student numbers.
While the government is trying very hard to reduce classes in order to avoid closing some schools, officials are obviously blind to the success of small-class teaching in primary schools.
In small classes of around 20, teachers can give each student more time. This makes teaching more effective. With a better educational system, students can have the chance to learn in a more effective way. Once they have grown up, they will be able to serve society in more ways and improve it.

Second-hand smoke affects children
Smoking really hurts children. Not only will second-hand cigarette smoke destroy children's health, it will also affect their psychological growth. As smoking is a social custom, when parents and their friends smoke around a child, they provide a powerful model that may influence youngsters' actions. They may follow suit and light up when they grow older.
As a result, the number of children with health problems will rise. Tobacco is already a major cause of death around the world.
I consider second-hand cigarette smoke to be a serious social problem, much like the city's drug problem. The government should provide more education on the harm caused by second-hand cigarette smoke.

Consider others when on MTR
When travelling on the MTR, I have noticed some very anti-social behaviour.
As soon as they get into a compartment, some people will immediately start talking loudly into their mobile phones. Sometimes they also laugh uncontrollably. Some play NDS, PSP or other games and turn the music up to the highest volume. These are not just teenagers, but also adults.
It is very annoying when someone is talking loudly or playing loud music. Everyone wants to rest on their way home.
I'd like those people to consider others. They should talk softly and turn down, or even turn off, their music. Then everyone will have a comfortable and relaxed journey.
