rivers have been polluted, rubbish is everywhere, factory chimneys have given off too much smoke causing lots if avid rain all over the world, which has damaged not only crops, but also plants. besides, men himself also have done a great dead of harm to the environment.
ok. according to the pictures, answer the following questions
1. what is the biggest problem facing the earth? why do you think so?
i think water pollution is the most serious problem facing the earth because we need clean drinking eater to survive and because animals and plants must have clean water, too.” if water is polluted. people will not be able to get clean water to drink; therefore, many people will get sick, it’s terrible.
2. what causes the problems?
i think it is because people pay no attention to our environment. they pour water into rivers, lakes and seas without cleaning it
the air pollution is caused by the factories. people build factories to develop the industry, but they never pay attention to controlling the pollution. the harmful smoke should be made harmless before it goes into the air, but few factories would like to d so because this will cost much.
3. what can we do to solve the problem?
i think our government should pay more attention to environmental protection, they should check the factories as often as possible to make sure they don’t pour waste water into rivers or lakes and make sure they don’t let harmful smoke go into the air.
