How does air pollution affect humans negatively?

• Tiny particles in the air clog our lungs and make it hard to breath and get oxygen (O₂) to our heart. Some will die.

• Air Pollution adds gasses to the atmosphere that thickens the blanket around the planet and increases the global temperature.

• Air Pollution leads to higher temperatures which leads to melting glaciers which adds water to the oceans.

• Air Pollution leads to higher temperatures which leads to more evaporation which means more water vapor in the air which leads to more sever storms.
