Pollution
Definitionadding harmful substances or products into the environment
The use of FOSSIL FUELS are the biggest cause of pollution
What are fossil fuels?
Oil, gas, and coal Easy to use and contain a lot of energy They can affect the environment in many
ways
Air Pollution
Pollutants (such as burning fossil fuels) released into the atmosphere can have harmful effects. Smog Depletion of the ozone layer Creation of acid rain
Some causes of air pollution- Car emissions factories
Air Pollution
Effects on the environment can include Health risks to living organisms All air pollutants return to the ground in some
form which effects the surrounding landscape

Air Pollution- Effects of acid rain
Air Pollution-Ozone depletion
Water Pollution
When pollutants are added to the water supply Oil spills Fertilizers (chemicals)
Water Pollution
When a water supply is contaminated, not only are aquatic plants and animals affected, but also any organism that needs that water to survive

Land Pollution
Humans produce hundreds of millions of solid waste each year…..
Where does it go?
To a landfill!

Human Development/Population
Today there are more than 6 billion people on the Earth What does that mean for the planet’s biotic and
abiotic factors?
Less resources (food, water, land, etc) Loss of habitats
What if…….
An ecosystem of forests was destroyed and replaced with a large shopping mall?
Predict how this will most likely affect the environment of the area. Result in habitat destruction Decrease in animal population Increase pollution
What if……
As a city’s population grows, wooded areas are replaced by housing developments.
What effect will this most likely have on the species in the wooded areas? Many of the species will leave the area Some may die if there is no other habitat
available

The use of fossil fuels is the major cause of pollution
