Environmental problems have become one of the most urgent problems of modern society. More and more people suffer from air and water pollution. Nature also suffers from land and nuclear pollution. The reasons for such environmental problems are numerous. Among them increasing number of cars in the streets, factory waste, millions of cut down trees, destroyed habitats of animals, contaminated rivers and seas. All these problems mainly arise due to human careless activities and gradually destroy our planet. If we look closely, we’ll notice that not only one city is under danger, but the majority of world population. Fortunately, there are many ways to suspend these problems. If everybody starts caring about the planet we live on, many environmental problems can be solved. For example, if we start recycling paper and cardboard, we can save lots of trees. If we start using public transport more than private cars, we can have less air pollution. Local governments can also help to prevent some problems, if they forbid logging companies to destroy the forests, or stop factories from polluting water. The most important thing is, of course, to start acting immediately, otherwise we might have to face many global disasters.

Волк видел Овцу у речки и хотел поесть его. Он крикнул: "я не могу пить эту грязную воду! Это грязно! Вы гадили воду. Вы помещаете свои грязные стопы в воду"! 
"Нет, я не гадил это" Овца ответила. "Я не поместил свои стопы в воду. Я пью с моим ртом и не с моими стопами. Посмотреть! Мои стопы не находятся в воде". 
"ХОРОШО.это был год.Ты помещал свои стопы в воду в году"! Волк крикнул. "И ты гадил воду". 
"Но я - только четыре старых месяца," Овца сообщила. "Как смог я поместить мои стопы в реку год назад"? 
"Если это не был ты, это был твой брат или твой отец," Волк крикнул и выскочил на бедную Овцу.
