Study Notes
The Atmosphere
- Air is a mixture of gases, essential for life and also harmful pollutants
- Air contains nitrogen (~78%), oxygen (~21%), argon (~0.93%), carbon dioxide (~0.03%), other inert gases (very small quantities), water vapor (~1% varying quantities), and pollutants (varying quantities)
Pollution
- Pollution is the contamination of the environment by harmful substances
- Pollutants harm life
- Key concerns for environmentalists include acid rain, water table contamination, and landfill build-up of non-biodegradable materials (all caused by irresponsible human practices)
- Increasing pollutants in the air, water, and land impact health
- Ozone layer depletion (by harmful substances like CFCs, used in refrigerators, aerosols, and air conditioners) causes increased harmful UV rays
