17. I Can… 1. List 3 kinds of pollution
2. Describe how habitat destruction affects biodiversity
TOC # 1 Environmental Solutions & Biodiversity

18. Environmental Problems and Solutions
You’ve probably heard it before. The air is unhealthy to breathe. The water is harmful to drink. The soil is filled with poisons. The message is…
I can list 3 kinds of pollution.
I can describe how habitat destruction affects biodiversity.

19. Earth is SICK and in great DANGER!
I can list 3 kinds of pollution.
I can describe how habitat destruction affects biodiversity.

20. Pollution
An unwanted change in the environment caused by substances, such as wastes, or forms of energy, such as radiation, is called pollution.
Anything that causes pollution is called a pollutant.
Some pollutants are produced by natural events, such as volcanic eruptions. Many pollutants are human-made. Pollutants may harm plants, animals, and humans
I can list 3 kinds of pollution.
I can describe how habitat destruction affects biodiversity.

21. There are five kinds of pollutants
Garbage - This trash often goes to a landfill
Chemicals - The same chemicals that help
people may harm the environment.
I can list 3 kinds of pollution.
I can describe how habitat destruction affects biodiversity.

22. High-powered waste - Nuclear power plants produce radioactive wastes.
Gases – Due to more human technologies, such as
cars, more CO2 is in the atmosphere.
Noise - affects your ability to hear and think clearly,
and it may damage your hearing
I can list 3 kinds of pollution.
I can describe how habitat destruction affects biodiversity.

23. Discuss with elbow partner.
Question…
What is the difference between renewable and nonrenewable resources?
Which is better for our environment? Why?
I can list 3 kinds of pollution.
I can describe how habitat destruction affects biodiversity.

24. Distinguish between renewable & nonrenewable resources.
A renewable resource is one that can be replaced at the same rate at which the resource is used.
A non-renewable resource is one that cannot be replaced or that can be replaced only over thousands or millions of years
I can list 3 kinds of pollution.
I can describe how habitat destruction affects biodiversity.

25. Resource Depletion Renewable Resources can be used again and again.
Example: solar energy
I can list 3 kinds of pollution.
I can describe how habitat destruction affects biodiversity.

26. Nonrenewable Resources
Nonrenewable Resources can only be used once.
Example: fossil fuels, such as oil and coal
Coal

I can describe how habitat destruction affects biodiversity.

27. Renewable or Nonrenewable?
Scientists used to think that fresh water was a renewable resource.
However, in some areas, water supplies are being used faster than they are being replaced. Scientists are working on ways to keep these water supplies from being used up.
I can list 3 kinds of pollution.
I can describe how habitat destruction affects biodiversity.

28. Habitat Destruction
When land is cleared for construction, crops, mines, or lumber, organisms that were living in the areas may be left without food and shelter. These organisms may die.
An organism’s habitat is where it lives. Every habitat has a number and variety of organisms, or biodiversity. If a habitat is damaged or destroyed, biodiversity is lost.
I can list 3 kinds of pollution.
I can describe how habitat destruction affects biodiversity.

29. Forest Habitats: Trees provide humans with oxygen, lumber, food, rubber, and paper. For some of these products, trees must be cut down. deforestation is the clearing of forest lands.
I can list 3 kinds of pollution.
I can describe how habitat destruction affects biodiversity.

30. Marine Habitats: Spilled oil pollutes both open waters and coastal habitats. In addition to oil, chemicals and plastics are sometimes dumped into marine habitats.

31. How pollution affects humans.
Polluted air affects people with respiratory problems.
Polluted drinking water makes people sick. Some chemicals that pollute water cause cancers many years after exposure to them.
I can list 3 kinds of pollution.
I can describe how habitat destruction affects biodiversity.

32. The importance of conservation.
Conservation is the preservation and wise use of natural resources.
Example: riding a bike instead of driving a car

List at least three ways.
I can list 3 kinds of pollution.
I can describe how habitat destruction affects biodiversity.

35. How biodiversity can be maintained.
Protecting species: One way to maintain biodiversity is to protect individual species. In the United States, a law called the Endangered Species Act was designed to do that.
Protecting habitats: Each organism is part of a huge, interconnected web of organisms. The entire web should be protected to protect these organisms.
