Quiz Review – Questions 7 & 14

Pollution Spreads

Broadly speaking, pollution occurs in three areas: air, land, water

Key Point #1: Pollution in one location (air, land, or water) often negatively affects life in the other two locations All life is tied together!

Air pollution may affect life in water and on land

Land pollution may affect life in water and air

Water pollution may affect life on land and in air

Why?

Remember: as biodiversity decreases, food webs become less stable Organisms in air, water, and land all depend on each other for food

If enough organisms die, the food web will collapse

Pollution produces BIG environmental changes If temperature increases (global warming), life is affected EVERYWHERE

The same goes for increased UV radiation (ozone depletion), changes in pH (acid rain), etc.

The Point

Key Point #2: In order to protect life on Earth, we have to keep our land, water, AND air pollution-free It does no good to clean up pollution in one area without cleaning up the others

Pollution spreads from one area to the others!

Don’t Believe Me?

Six stations, five minutes at each station Biodiversity Global warming Ozone depletion Acid rain Agricultural runoff Big Picture
