[00:04.99]Lesson 21            1 Dialogue

[00:11.23]Mr Zhr is taking a school party to the seaside.

[00:17.11]They have just arrived at the beach.

[00:21.05]MR ZHU:OK,everyone.Less noise,please! Gather round and listen carefully.

[00:27.90]First we are going to search the beach and the rock pools.

[00:32.94]Let me remind you what we are looking for:seaweeds,fish,plants,all living things.

[00:41.80]When you find anything,make a note where it's found,

[00:46.94]and do a drawing in your notebook.

[00:50.78]Then we'll meet here at 12 o'clock and have a swim before our picnic lunch.

[00:57.23]Don't rush! There's plenty of time.

[01:01.60]An hour later.

[01:05.15]JANE:Mr Zhu,have you seen the sea?

[01:10.43]MR ZHU:Of course,I have!It's all around us!

[01:14.58]JANE:No! I mean,have you seen how dirty the water is?

[01:20.93]It looks as if it isn't clean enough to bathe here.

[01:26.00]MR ZHU:Goodness!Now I see what you're talking about.

[01:31.64]JANE:It seems that there is a big waste pipe coning 1 down from the town.

[01:37.41]Do you see it,over there?

[01:40.65]MR ZHU:Yes,I see.How can they get rid of waste water in this way?

[01:48.20]What a terrible colour the sea is now!

[01:52.64]It looks as if our class won't be able to bathe at all.

[01:57.50]JANE:What a pity!

[02:00.74]MR ZHU:No matter how much you want to bathe,it just isn't safe.

[02:05.91]JANE:I suppose it's better to be safe than sick.

[02:24.27]DEALING 3 WITH WASTE

[02:27.83]How to get rid of waste is a great problem for the world today.

[02:33.70]Waste must be treated so that it does not become a danger to life.

[02:39.95]Unfortunately,

[02:43.00]in some countries waste from factories is still poured straight into rivers.

[02:50.16]People who use the water from one of these rivers ofthe get sick.

[02:56.82]The water may become so polluted 4 that it kills all the fish in the river.

[03:04.08]When this river finally reaches the sea,it pollutes the ocean.

[03:10.64]In many countries with sea coastds,

[03:14.72]human waste is piped directly 5 into the sea withort being treated.This is unsafe.

[03:23.55]Although the sea breaks up the waste,

[03:27.52]beaches may become polluted and fish may not be safe to eat.

[03:33.68]A better method is to take the waste far out to sea in ships

[03:40.16]where the wind and waver 6 break it down.

[03:44.42]In 1989 an international law was passed to stop people putting waste into the sea.

[03:52.36]It is now against the law to throw anything into the sea

[03:57.92]within 5 kilometres of land.

[04:01.79]Plastics and other similar rubbish that soes not break down

[04:08.03]may not be thrown into the sea anywhere.

[04:12.40]Other waste may be thrown into the sea,either 19 kilometres from land,

[04:20.26]or morethan 40 kilometres from land,depending on the nature of the materials.

[04:27.42]Some dangerous waste is still put into metal containers

[04:33.37]and thrown into the deep sea.

[04:36.92]It will be many years before the chemicals start to escape from the containers.

[04:42.88]At the bottom of the ocean there is very little life

[04:47.92]and very little movement of the water.

[04:51.87]It is therefore unlikely 7 that the chemicals will be carried upwards 8

[04:57.61]into the water where fish are found.

[05:01.87]At one time,certain types of radioactive 9 waste

[05:06.91]were put in the sea in metal containers.

[05:11.04]Now,however,all radioactive waste must be stored on land.

[05:17.81]The problem of dealing with waste has become so great

[05:23.37]that several international organizations,such as "Friends of the Earth",

[05:29.82]have been set up to protect the world and to fight against pollution

[05:36.30]They seek to reduce waste,protect the earth,

[05:41.66]the oceans and all forms of life in them.

[05:46.51]Recently,China has made special laws to deal with waste and control pollution

[05:53.88]She has also been very active in protecting the environment.

[06:00.05]THE THROW-AWAY SOCIETY

[06:03.70]In western countries,mountains of rubbish are thrown away each day.

[06:10.34]This causes many problems.

[06:14.28]First,areas of land must be found where this rubbish can be put.

[06:21.13]This is a particular problem for large cities.

[06:25.88]Second,much energy is wasted producing things that are thrown away.

[06:33.25]In China,rubbish,such as used plastic bags

[06:39.20]and boxes known 10 as "white pollution"is becoming a serious problem.

[06:46.28]Many lakes and rivers are polluted by the wastes from factories.

[06:52.34]As the wealth of the country increases,more waste will be produced.

[06:58.59]If everyone in the country bought one soft-drink can each day and threw it away,

[07:05.95]there would soon be a huge mountain of rubbish.

[07:10.60]Here is a game to play.

[07:13.87]The table below shows how much rubbish is thrown away in Britain every year.

[07:20.40]Imagine that China threw away as much rubbish as a country like Britain.

[07:27.03]China is 22 times larger than Britain.

[07:32.28]So,multiply the total for Britain by 22 (x 22)

[07:38.84]This will show you how much rubbish China would throw away each year.

[07:58.69]RECYCLING WASTE

[08:02.04]European countries are now making an active effort

[08:07.99]to reuse 11 materials more than they used to.This is called recycling.

[08:16.07]Materials such as paper,glass or metal are collected,sorted,

[08:24.11]treated and used again.Old newspapers are recycled.

[08:31.69]The ink is taken out by a special technique,and new paper is made.

[08:39.94]Oil from factories and motor 12 oil can be treated and reused 13.

[08:47.52]In many cities in Europe rubbish kis coll ected separately 14.

[08:53.68]Empty glass bottles are collected,

[08:58.23]and the glass is brlien and reused for making new bottles.

[09:04.76]Developing countries all over the world already recyle materials.

[09:11.60]In India,waste paper is collected,sorted,and recycled.

[09:18.86]Paper bags are are made from unsold newspapers.

[09:24.51]In Egypt,waste is collected by rubbish carts 15 and souted.

[09:30.88]Leftover food is given to pigs and vegetable matter is prt back onto the fields.

[09:39.24]In some Asian countries,shoes are made from the rubber of old car tyres 16.

[09:46.79]The Chinese government is also working hard against pollution.

[09:53.45]More than 60,000 small factories

[09:58.62]which seriously polluted the environment were shut down in 1996.

[10:06.38]Many materials like used rubber gloves,glass bottles

[10:12.73]cans and other containers are treated or recycled.

[10:19.10]However,no single country can save the environment alone
