××× Air , water and land pollution are the most dangerous yet poisonous lesions(آفاة) that effect the earth and threaten the human existing. For example, the emissions of greenhouse gases contribute to climate change, ozone layer depilation and ,the worst, to the acid rain that would damage the crops and cereals fields. Moreover , the exposure to air pollution causes a variety of different health outcomes such as the risk of respiratory infections that cause people to have breathing difficulties which would systematically lead to lung cancer and asthma. Worse, water and land pollution are the most hazardous. For, using or drinking polluted water results not only in skinrash but also effects the heart and kidney's natural functioning. Hence, pollution is a double edged sword that effects badly both parts : the earth and the human life ) , and therefore people around the globe must start think wisely of it in order to reduce its effects. For example , governments around the world may replace plastic utilities with other things that are capable of being reused such as plastic begs and bottles . Additionally , Factories and the means of transport (cars, trucks , buses...) should start using nature-friend items to get rid of the heavy smoke, such as electricity instead of fuels and petrol .
