  8. Landfill • However, are there any problems with landfill? • Landfill can be full!

  9. Knowing more about the landfill problem • Reading activity • Group yourselves into student As and student Bs. • Student As get article A, student Bs get article B • READ the articles individually and COMPLETE worksheet 1(A and B). • Now, you are going to form expert groups to check your answers. Later you will have to REPORT the information you get from the expert group to your home group.

  10. Know more about the landfill problem • Student As please stand up. Each of you find another student A and sit down. • Student Bs please stand up. Each of you find another student B and sit down. • Check your answers with your partner. • Now everyone return to their home group. (student A works with student B again) • Now work TOGETHER to complete Worksheet 2 • REMEMBER! DO NOT show your article or Worksheet 1 to your partner!!

  11. Check your answers! The landfill problem is very serious in Hong Kong. It can be shown by a few facts of landfills. For example, a huge amount of waste is released from our home. The amount is as much as (Hint: Amount of household waste) 1. 1.35 kilograms per day . The rubbish is then sent to the landfill by lorry. The amount is large. For example, (Hint: Amount of waste sent) 2. over 6,000 tonnesof waste is sent to Nim Wan landfill every day. Then, the rubbish is dumped into such large holes as (Hint: how large are the holes?) 3. thesizes of football pitches

  12. Check your answers! If the situation does not change, the landfills will be full in (Hint: The expected date for the existing landfill to be full) in 4. 2015. Later we have to find more places to build landfills. But even there are new landfills, they cannot last long. They will all be full in (Hint: The expected date for the new landfill to be full) 5. 2030. To help with the situation, there are a few things which the government can do. For example, the government can learn the experience from Japan to 6. pass laws to make producers and the people who buy their products share the cost of recycling the packaging. Besides, the government can also 7. pass a law to make people separate their waste. Taipei has also done this and (What is the result?) 8. the city has reduced its waste from 3242 to 1546 tonnes a day.

  13. Check your answers! And Hong Kong has actually done something to help. For example, Since 2004 we 9. have had a rechargeable battery recycling programme. However, (Hint: what was the result?) 10. people still throw their mobile phone batteries away. I think (Hint: what can be done to help?) 11. there should be a law to make people recycle their old batteries.

  14. What can WE do? • Besides the government, WE can also help to solve the problem of landfill! • What exactly can we do?

  15. Suggestions for solutions of waste problem • Instructions: • Student A gets Worksheet 3A and student B gets Worksheet 3B. • Worksheet 3A and 3B contain different information and you will need to WORK WITH your partner to write CONDITIONAL SENTENCES about how we can help with the waste problem. You will need to PRESENT your sentences to your classmate later. • Reminder: DO NOT SHOW your worksheet to your partner!! • A few tips on conditional sentences: • Type 1: talk about things quite sure, but not 100% • Structure: If + present tense, simple future tense. • Type 2: talk about things that you imagine/not true • Structure: If + simple past tense, WOULD + base form of a verb • E.g. If everyone in HK reused plastic bags instead of throwing them away, a lot of waste would be reduced.
