 Mobile phones
 People
 Animals
 Brainstorm some ideas.
 In Hong Kong, it’s difficult to stop building new
flats and buildings.
 We can plant more trees near flats to stop sound
traveling into your window.
 We can use good windows that stop noise traveling
through them when they are closed.
 We can keep quiet.
 We can respect our neighbours.
 There are ways to make our city sound nicer.
 People, even unborn babies, respond to nice sounds.
 People like the sound of waterfalls falling, birds
singing, insects chirping and waves crashing.
 Watch this video by the South China Morning Post
about ways to improve the sounds in Hong Kong.

Heat (thermal) – from
factories and nuclear

 Now there aren’t many lakes, rivers or estuaries that are safe for

people to bathe, fish or drink.
They also cause thermal pollution (heat pollution) which kills
fish and plants.
People in Hong Kong can’t see blue skies during the day or stars
at night.
It destroys the ozone layer which protects us from harmful
radiation from the sun.
There is a big hole in the ozone layer over Australia and New
Zealand, so people there get skin cancer and sun burns a lot.
Children there must wear hats and sunscreen every day or they
can’t go outside.
