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.
Проблемы окружающей среды стали одной из самых насущных проблем современного общества. Всё больше людей страдает от загрязнений воды и воздуха. Природа также страдает от загрязнения земли и от радиоактивности. Причин для таких проблем окружающей среды множество. Среди них, повышение количества автомобилей на дорогах, отходы заводов, миллионы срубленных деревьев, разрушение естественной среды обитания животных, загрязненные реки и моря. Если присмотреться, то можно заметить, что не только один город в опасности, но и большая часть населения мира. К счастью, есть много возможностей приостановить эти проблемы. Если все начнут заботиться о планете, на которой живут, многие экологические проблемы могут быть решены. Например, если мы начнём утилизировать бумагу и картон, мы многие деревья. Если мы начнём использовать больше общественный транспорт, чем личные автомобили, у нас будет менее загрязнён воздух. Местное правительство может также приостановить некоторые проблемы, если запретит лесозаготовительным предприятиям разрушать леса, или остановит заводы от загрязнения воды. Самое важное, конечно же, начать действовать сейчас, или нам придётся столкнуться со многими глобальными катастрофами.
