[00:07.00]1 Listen to the tape and fill in the correct information in the spaces below.

[00:15.15]1.Walk along the street of any major city,

[00:21.32]and you will see that the air you breathe is not very fresh.

[00:27.27]Air pollution is a serious problem in many of the world big cities.

[00:33.72]It is caused by cars and factories.

[00:37.98]We also pollute the air when we burn oil or coal for energy and heat.

[00:44.75]2.Oh,my,look at this,dead fish everywhere

[00:51.51]What happened? We used to be able to drink the water in rivers and lakes.

[00:58.46]But today,many rivers and lakes have been so polluted that the water is useless.

[01:05.93]Factories' and drainage 1 have been polluting the water.

[01:10.66]We aren't taking good care of water.We use too much water and we waste water.

[01:18.11]What is more we pollute water.

[01:22.18]3.This beautiful mountain is one of the most popular places for people to visite,

[01:30.04]during holidays and festivals.

[01:34.09]Thousands of people come here to hike in the mountains forestes and valleies.

[01:40.57]Unfortunately the tourists leave a lot of rubbish behind,

[01:46.81]plastic bags,soda 2 bottles and other things are thrown everywhere.

[01:53.79]Many tourists also pick flowers and demadge the trees.

[01:59.54]And the many hotels in restaurants beening built

[02:04.19]are having a negative affect on the environment,too.

[02:09.36]READING ARE WE ENDANGERED

[02:22.32]Steve Jones is an environmental expert who tries to keep animals and plants

[02:29.58]from becoming endangered.

[02:32.95]"We are not alone in the world.

[02:36.60]We human beings could not survive without all the plants and animals around us.

[02:43.27]We often talk about how important it is to take good care of ourselves and our planet 3,

[02:50.03]but we don't always do as we say,"

[02:54.18]Steve says as he takes us on a tour of  Green Park in Birmingham.

[03:00.06]Many of the earth's plants and animals have already died out,

[03:05.70]and several other species 4 are endangered.

[03:10.07]If we want to live a better life and have a bright future,

[03:15.42]we must learn to act in ways that do not harm other living things.

[03:21.67]If we know more about what causes endangerment,

[03:26.32]we may be able to take measures before it is too late.

[03:31.67]A species can become endangered for different reasons.

[03:36.84]Animals and plants must have a habitat,or home,which is comfortable and clean,

[03:44.39]and where there is enough food and other resources.

[03:49.56]They are all used to their environment;

[03:53.33]that is,they have learnt how to live successfully in their habitat.

[03:59.49]When the habitat of a species is changed or destroyed,

[04:05.13]the animal or plant has to either adapt to the change or find a new home.

[04:12.00]If this is not possible,the species becomes endangered.

[04:17.65]If a new species arrives,the animals and plants of the habitat must change again.

[04:25.22]If the new species is too strong or uses too much of the resources in the hatitat,

[04:32.59]some of the original species may become endangered.

[04:37.73]A species may also die out

[04:41.97]if humans or other animals use too much of a plant or kill too many animals.

[04:49.52]The good news is that there is a lot we can do to help.

[04:55.16]First of all,we need to learn more about animals,plants and the environment.

[05:02.13]Experts tell us that we need to think about what we can do

[05:07.70]to keep animals and plants from becoming endangered.

[05:12.45]Steve says that we can help by creating more space for animals and plants:

[05:19.40]"You can plant a tree or build a birdhouse.It is simple but useful."

[05:25.85]Steve also wants us to think about what we do:

[05:30.42]"Please don't pollute the environment."

[05:34.08]If we find out more about what we should do,

[05:38.83]we can help Steve and others like him keep animals and plants

[05:44.76]and ourselves from becoming endangered.

[05:49.60]INTEGRATING SKILLS

[05:55.84]Reading and writing

[05:59.18]Without air,water and sunlight there would be no living things.

[06:06.92]Because they are so important,

[06:11.17]ecosystems try to be very careful with these valuable resources.

[06:17.73]Human beings often throw away things they have used only once.

[06:24.10]In good ecosystems,resources are used many times.

[06:30.35]The waste of plants and animals will become food for another.

[06:36.30]In fact,nature is much better at recycling than we humans are.

[06:42.96]Maybe we should learn from nature

[06:47.22]and become better recyclers if we throw away too much,

[06:53.88]we may be throwing away our future.

[06:58.56]We all care about nature and the environment,

[07:03.92]but we may not always do everythings we could or should.

[07:09.77]Scientists who know a lot about the environment say that we should

[07:16.14]"Reduce, Reuse,Recycle and Respond".Let's see what that means.
