объяснение:

перевод:

есть множество городов с проблемой экологии. мы зачастую не замечаем до чего грязен наш город. и что же мы можем поделать? 2) проблемы с мусором это ужасно. также, когда мы живём практичекси на свалке это совершенно не нормально. а те самые заводские трубы, из которых "льётся" черный дым? они тоже ужасно влияют на природу. 3) мы можем не выбрасывать мусор где попадая (на клумбах, в парках, около зданий), приносить и перерабатывать мусора, и т.д. 4) в заключение хочу сказать тебе, мой друг, береги природу сегодня, иначе завтра будет уже поздно.
