  • Slide 13
  • Brainstorm some ideas. In Hong Kong, its 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.
  • Slide 14
  • 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. Soundscaping Hong Kong

  • Slide 18
  • The make everything we use: Food Clothes Toys Cars Telephones Computers Furniture Jewelry
  • Slide 19
  • Factories are the number one cause of pollution. They pollute water, air and soil. They use water to wash away their waste. Now there arent 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 cant 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 cant go outside.
