Вывод
В ходе нашей исследовательской работы нам удалось выяснить глобальные экологические проблемы планеты в целом. Также мы подготовили топ стран, являющихся наиболее загрязненными. Далее мы определили какие проблемы в этих странах представляют собой наибольшую угрозу для жителей. Нами были разработаны несколько путей решения данных проблем.
