D)air pollution
Atmospheric air is the life of the planet, the Earth's gas layer consisting of nitrogen, carbon dioxide, ozone and helium. Oxygen is very important for biological processes, and carbon dioxide is essential for photosynthesis. A person has to go without food, but can not live without breathing, because the human body has limited oxygen reserves. It takes only 2-3 minutes to breathe, and after five minutes, due to lack of air, the human body begins an irreplaceable process, the cerebral cortex stops working, and biological death occurs.

Аудармасы:Атмосфералық ауа – бұл ғаламшардың (планета)өмірі, жердің азоттан, көмір қышқыл газынан, озоннан, гелиден тұратын газ қабаты.
Биологиялық процесс үшін оттегінің маңызы өте зор, ал көмірқышқыл газы фотосинтез процесіне өте қажет. Адам тамақ ішпеуге бар, бірақ тыныс алмай өмір сүре алмайды, себебі адам организмінде оттегі қоры шектеулі. Ол 2 – 3 минут қана тыныс алуына жетеді, ал бес минут өткен соң, ауа келмегендіктен адам организмінде орнына келмейтін процесс басталады, ми қабаты жұмысын тоқтатады, биологиялық өлім келеді.
