Answer these questions in your notes while the video is playing. How have we as humans contributed to the warming of the earth? What innovations or technology have we come up with to try and reduce the effects of pollution added to the atmosphere? Do you think Charlotte has the same pollution problems as other large cities?

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
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

The next 2 Videos describe what happens to the waste we produce at home
Reduce, reuse, recycle Water, pollution, waste, skip to 3:33
Land Pollution
Humans produce hundreds of millions of solid waste each year…..
Where does it go?
To a landfill!

Human Development/Population
Today there is about 7 billion people on the Earth
By 2050 (when you guys are in your 50s) the predicted population is expected to be around 9 billion people
Go back to the website on your phones and answer the following question. Do you think that our technology can prevent
environmental collapse, or will our planet be too far from saving by 2050?
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
Pollution
Air Land Water
Smog
Ozone Depletion
Acid Rain
Solid wastes
Landfills
Oil spills
fertilizers
Pollution- adding harmful substances or products into the environment
The use of fossil fuels is the major cause of pollution
Exit Ticket
What are the major contributing factors to pollution on our planet today?
What is the difference between a renewable resource and a nonrenewable one?
Give some examples of how we could help to relieve the strain on the environment caused by human pollution practices.
