The global warming is polluting the air. The air is affecting the atmosphere and slowly changing the weather in a negative way. When the weather or climate is changed then the plants that are supposed to grow will not grow correctly. As we know, plants clean the air but if there is a decreasing amount of plants then the air will become dirtier and more polluted with carbon dioxide. To much of this is toxic to humans so if we start to inhale more of that then oxygen, we will become more ill and have a greater risk of death an potentially extinction.
