1. Conservation and Pollution

2. Essential Questions
How do I identify distinguish, and correct effects of pollution?
What are the effects of pollution on plants, animals, and their habitats?
How does conservation protect our environment?
How does recycling help reduce pollution?

3. Vocabulary conservation contamination endangered species environment
extinction
pollution
preserved
recycle
survive
synthetic fuels

4. Pollution Dictionaries describe Pollution / Pollute / Pollutant as
Impure; act of making unclean; contaminating
Substance that pollutes; chemical or waste products defiling the air, soil, or water

5. Pollution comes in many forms.
Water
Land & Soil
Air
What things do we do that pollute the water, land, and air?

6. Background Info:
Water Cycle
All living organisms are dependent on clean and safe water to live. Some of us need a lot, others do not need as much.
Water cannot be created. It is something that exist on earth and is recycled.
The Water Cycle is how the same water is used and reused on earth.

7. Water Cycle
Pollution of the water not only hurts organisms that live in the water, but can hurt organisms that live on the land.
Acid Rain
chemicals mix and get into the water / air and comes back down as acid rain. The chemicals in the rain eat away at our buildings – bricks, metals, etc.

8. Water Pollution Water pollution is when…
We dump trash directly or indirectly into the water, drains, and sewers – lakes, ponds, and rivers
Plastics and general trash hurts the organisms in the water – fish, penguins, birds
Chemicals get into the fish and into the food chain
Chemicals and oils coat fish, birds, and other animals
Imbalance of one organism on the food chain – disruption in the life cycle.

10. Class Discussion What are the effects of Water Pollution?
How do I identify distinguish, and correct effects of pollution?
What are the effects of pollution on plants and their habitats?
What are the effects of pollution on animals and their habitats?

11. Air Pollution
Air Pollution deals with unnatural and natural things in the air.
Noise is a type of pollution
Chemical from cars, factories, aerosol…
Imbalance of certain gases that occur naturally
Greenhouse effect
Climate Changes

12. Air Pollution Noise Pollution Stress on humans
Frightens animals away from their habitats
Scientist think there may be a link to noise pollution and well-beings of some animals
Example: dolphins and whales use sound for communication - our noise pollution disorients them

13. Ozone and the Greenhouse
Background Info:
The Sun, our main source of energy and heat, is gives off a lot of dangerous radioactive materials.
The Earth is protected from most of these radioactive rays by our atmosphere. It is like a protective glass case.

14. Ozone
What would happen if we punched a hole in this protective glass case?
The Ozone is damaged a tiny bit by nature
Volcanic eruptions
Naturally occurring chemicals
BUT – we humans are doing things to damage the ozone a lot!!!
Chemicals released in the air
Less Ozone, More harmful rays
It kills certain animals – food source for others
Causes diseases in us - cancer

15. Greenhouse
The Earth’s atmosphere helps to trap the sun’s heat…. enabling us to live.
What if too much heat was trapped?
Weather changes – too hot
Ice on earth melts
higher water levels
Disappearing land
Imbalance of natural gases that give us life
More carbon dioxide, more food for plants, more plants
More pollen and allergens for us

16. Greenhouse
The chemicals, Carbon Dioxide (CO2) we release in the air through our cars, factories, and other industries causes more heat to be trapped in the Earth’s atmosphere – the Greenhouse effect

17. Class Discussion What are the effects of Air Pollution?
How do I identify distinguish, and correct effects of pollution?
What are the effects of pollution on plants and their habitats?
What are the effects of pollution on animals and their habitats?

18. Land Pollution Trash is Ugly Trash can cause fires – air pollution
Trash gets carried into our water supply – water pollution
Trash causes waste.

19. Misuse of Land
When we farm too much or cut down too many forests, we are polluting the land.
Too much farming strips the land of nutrients and soil protection (causes erosion)
Main effect on the environment is that animals are now left homeless
Animals will migrate to unwanted areas and have to find new sources for food

20. Severe soil erosion in a wheat field near Washington State University.
Some farmers terrace their land so gravity and “land slides” will not erode away land

21. Pollution Summary
There are many ways to pollute the water, air, and land.
Pollution is caused by many different things.
Pollution hurts us all – directly and indirectly
Interferes with the food chain
Interferes with organisms’ habitats

22. Conservation Conservation is one way to reduce pollution.
Conservation deals with the smart use of our resources (like the smart economic decision making we learned in Social Studies)
We have limited resources!
We should conserve because:
We want to reduce pollution
Does every living organism deserve a safe and happy habitat?
We are all dependent on each other for a happy and healthy life - food chain.
The entire planet is our habitat!

23. What to Conserve? Why Recycle
We can conserve our natural resources.
Water - Elements
Other materials – coal, trees, etc.
We can conserve energy.
Making usable energy takes a lot of resources and can cause a lot of pollution
Recycling helps us to conserve

24. Conservation and Recycling
Recycle paper helps use reduce the number of trees we need to make more paper
Turning off lights reduce the amount of electricity you use
You save your parents money
We need less electricity
Making less electricity causes less natural resources to be used and less pollution

25. Conservation and Recycling
Eat all your food or take only what you will eat.
Less use of factories that help package your food
Less growing and hunting of plants and animals that provide us our food
Conserve water
We will need less energy to clean the water if you do not let it all go down the drain.
Always make sure the water you drink is safe!
Don’t drink from ponds, lakes, or rivers.
Stay on the sidewalks
Don’t hurt nature in parks or wildlife areas
These areas could be some other animal’s habitat!
Don’t cause erosion!
