Our atmosphere is a complex and dynamic natural gaseous system that supports all life on Earth. In the past, our planet was able to absorb small quantities of pollutants. In the last 100 years, however, the introduction of cars and increased industrialization has contributed to a growing pollution problem. Ozone depletion due to air pollution is a threat to both human health and Earth's ecosystems.

To combat this threat, more and more countries are enacting stricter clean air laws and coming together to enforce international treaties that regulate air pollution in order to slow global warming. It is up to all of us to make changes to ensure clean air for all life on Earth.
