Human activities release substances into the air like tiny particles from burning fuel and gases such as sulfur dioxide and carbon monoxide, which can then chemically react to form smog and acid rain. The greenhouse effect and global warming are attributed to a buildup of carbon dioxide in the atmosphere, while ozone depletion stems from pollution affecting the stratospheric ozone layer that protects the earth from ultraviolet radiation.

- 3. Air is 99.9% nitrogen, oxygen, water vapor and inert gases. Human activities can release substances into the air, some of which can cause problems for humans, plants, and animals.
- 4. This is the release of tiny particles into the air from burning fuel for energy.
- 5. Another type of pollution is the release of gases such as sulfur dioxide, carbon monoxide, nitrogen oxides, and chemical vapors. These can take part in further chemical reactions once they are in the atmosphere, forming SMOG and ACID RAIN .
- 6. The Greenhouse Effect, also referred to as global warming, is generally believed to come from the build up of carbon dioxide gas in the atmosphere. Ozone depletion is another result of pollution. Chemicals released by our activities affect the stratosphere , one of the atmospheric layers surrounding earth. The ozone layer in the stratosphere protects the earth from harmful ultraviolet radiation from the sun.
