We live in a world full of different types of pollution. Wanting to make their lives easier people have invented so many new devices and factories, that nature is in danger. Unfortunately, environment is not the unlimited source of resources. At the moment, our planet suffers from numerous problems and damages. For example, acid rain, which is the result of waste gases from power stations. Such rains cause forest damages. Other big problems are water shortage and the destroying ozone layer. It is all the result of pollution that comes from factories and plants. Wildlife suffers as well. Many species of animals and plants start to disappear. Another big issue is global warming and green house effect. As you can see, there is a long list of environmental problems, which need to be solved. Otherwise, our planet Earth may get fully destroyed. People should start dealing with these problems immediately. The most important thing they can do is to change their attitude towards the environment. First of all, people should switch to alternative forms of power, such as wind power or solar energy. Secondly, the use of nuclear power should be banned. Thirdly, we should start to recycle. It’s the art of turning waste into new products. Other than that, the number of harmful plants should be reduced because they pollute the air and water greatly. It would be a good idea if people started using bicycles instead of cars. We are obliged to protect nature. If everybody cares, it would make difference.
Перевод
Мы живем в мире, полном различных видов загрязнения. Желая облегчить свою жизнь, люди придумали так много новых устройств и заводов, что природа находится в опасности. К сожалению, окружающая среда не является неограниченным источником ресурсов. На данный момент, наша планета страдает от многочисленных проблем и ущербов. Так, например, кислотные дожди, которые является результатом отходящих газов электростанций. Такие дожди наносят ущерб лесам. К другим крупным проблемам относятся нехватка воды и разрушение озонового слоя. Это все результат загрязнения, который происходит от фабрик и заводов. Дикий мир также страдает. Многие виды животных и растений начинают исчезать. Другой большой проблемой является глобальное потепление и парниковый эффект. Как видно, список экологических проблем, которые необходимо решить, длинный. В противном случае, наша планета Земля может быть полностью уничтожена. Люди должны начать решать эти проблемы немедленно. Самое главное, что они могут сделать, это изменить свое отношение к окружающей среде. Прежде всего, люди должны перейти на альтернативные формы энергии, такие как энергия ветра или солнечная энергия. Во-вторых, использование атомной энергии должно быть запрещено. В-третьих, мы должны начать переработку отходов. Это искусство превращения отходов в новую продукцию. Кроме того, количество вредных заводов должно быть уменьшено, потому что они сильно загрязняют воздух и воду. Было бы неплохо, если бы люди начали использовать велосипеды вместо машин. Мы обязаны беречь природу. Если бы все проявляли заботу, это бы возымело результат.
