Should concerts be held at Hong Kong Stadium?

I do not believe they should, for several reasons.

Take Sunday's concert by Sam Hui Koon-kit as an example.

These concerts create noise pollution and disturb residents living near the stadium. It is easy to understand why they would be annoyed by such concerts, whether it is during the day or at night.

Organisers of the Hui concert claimed they had the technology to enable them to lower the noise, but it was inefficient.

Also, at an indoor venue like the Coliseum, the sound is concentrated, but an audience at Hong Kong Stadium will not be able to enjoy such good sound effects.

Also, being open air, the system has no air-conditioning and this would make conditions very uncomfortable for the audience if a concert was held during the summer.

I do not think concerts should be held in Hong Kong Stadium.

If the sound equipment echoes, this cannot be enjoyable for the fans or the performer ('Bid to cut sound at stadium gets nod from neighbours but leaves Sam Hui fans cold', December 17).

It is also a nuisance for local residents. Surely, it is impossible to sit and enjoy a concert if you know that nearby residents are suffering as a consequence.

I believe that the noise of the music, combined with the response of the audience, are a cause of noise pollution.

The right venue for concerts is Hong Kong Coliseum.

What do you think about sex education in Hong Kong?

I do not have children studying in Hong Kong. However, from what I read in Choi Shuk-ching's letter (Talkback, December 13), I agree that letting children know only a bit about sex increases their curiosity.

However, why are we putting the onus just on schools to provide decent sex education? Society in general and parents are two very important and influential factors when it comes to children.

Children are bombarded every day with material of a sexual nature. There are films and programmes on television, which might make young people think that sex before marriage is all right.

If parents are working late, children are often left to amuse themselves. They are very impressionable and they may copy things they see other people do.

The government should be doing more in this regard, but whatever policies it adopts, they do not seem to be working well.

There is a serious problem with sex education in Hong Kong.

We see so many television programmes and adverts of a sexual nature, and then there are magazines and the internet. Young people see all these things, but it does not enable them to have an in-depth, mature understanding of sex.

If they have intimate relations, without understanding the full implications of that relationship and not being educated properly about sex, they may become pregnant.

Schools must provide better sex education so that the students are fully aware of the consequences.

The government must also set up more organisations which can provide the correct kind of sex education and which can help those teenagers who get pregnant. If pregnant teenagers are helped in this way, then hopefully it will prevent further tragedies.

Should ParknShop have stuck to its 'no plastic bags' policy?

ParknShop took the initiative when it launched its 'no plastic bags' policy.

I do appreciate that its intention was to help promote environmental protection and it should be applauded by all those who care about looking after our Earth.

Surprisingly, it was heavily criticised by legislators.

Why did it come under fire when an organisation was finally willing to take real action on the environment?

Hongkongers get so accustomed to criticising something, even when they have no sound reason to.

ParknShop has stopped the campaign because of pressure from different sectors. It is a shame the first major retailer that took an important step towards environmental protection was forced to give up.
