Объяснение:
At the present time, the issue of pollution is a huge problem.For example, the topic of air pollution.This is a very serious topic where you need to be sharp in questions.One of the huge reasons is the factories, where a huge amount of "poison" comes out, thereby worsening the air itself.We do not notice how the sky is covered with this gas.Also the smoke from the cars or a forest fire, and more harmful to our nature.So we have to solve this problem, because we are part of nature.
перевод:В настоящее время проблема загрязнения окружающей среды является огромной проблемой.Например, тема загрязнения воздуха.Это очень серьезная тема, где нужно быть острым в вопросах.Одна из громадных причин-заводы, где выходит огромное количество "яда", тем самым ухудшая сам воздух.Мы не замечаем, как небо покрывается этим газом.Также дым от машин или лесной пожар, и более вредный для нашей природы и прочее.Поэтому мы должны решить эту проблему,немедля, потому что мы-часть природы .
