What is Pollution?

  • Pollution is the introduction of contaminants into the environment that cause change

3 of 16

What causes pollution?

  • Pollution is mostly caused by human activities

​

Yes,

you humans!

4 of 16

Causes: Oil

  • Oil use is the main cause of pollution
  • Americans consume 22% of Earth’s oil

5 of 16

Causes: Waste

  • Waste such as sewage causes pollution by affecting organism/human environments
  • Sewage can enter oceans and kill many animals

​

6 of 16

Causes: Gas

  • One other major cause of pollution is motor vehicles
  • Harmful gasses from the vehicles pollute the air

7 of 16

Causes: Littering

  • Littering is a huge issue or cause of pollution
  • Many people litter each day and it piles up over time

​

8 of 16

Causes: Natural Disasters

  • Natural disasters can contaminate water
  • They can also cause air pollution and a dramatic change in weather or living conditions

​

9 of 16

Consequences

  • Harder living conditions
  • Less resources
  • Less animals
  • More Human diseases

Resolutions: Recycling

  • Recycling is a way everybody can help stop pollution
  • It is rather easy to do and has a great outcome

11 of 16

Resolutions: Less use

  • By less use, I mean less use of resources
  • If everybody uses the perfect amount of resources they need, or no extra resources, than pollution will decrease

12 of 16

Conclusion

  • Pollution is harmful
  • Humans mainly cause pollution
  • Many things can prevent it

You can help! Reduce, reuse, recycle!

Checking for Understanding

Biodiversity is valuable to humans because we depend on it to benefit from the many organisms and species.

Pg. 151-153 (#1-3)

1. Why is biodiversity worth preserving?

Biodiversity is one of Earth’s greatest natural resources.

2. List four different ways in which humans are decreasing biodiversity.

Humans decrease biodiversity by altering habitats, hunting species to extinction, introducing foreign species to new environments.

3. What is the focus of conservation biologists worldwide?

Conservation efforts focus on protecting entire ecosystems as well as single species.

Backtrack

The item I chose to observe and analyze was a pencil. The pencil is made of many resources which are below.

Pencil:

  • wood - renewable
  • glue - nonrenewable
  • metal - renewable
  • rubber - nonrenewable
  • graphite - nonrenewable

Transition Questions

1. A natural resource is anything that comes from nature. An example is crops.

2. A renewable resource is a resource that can’t be recycled while a nonrenewable resource is a resource that can’t be reused. Example of renewable: plastic. Example of nonrenewable: oil.

3. Pollution is the introduction of contaminants into the environment that cause change. Examples include; air pollution, waste, water contamination, and land pollution.

4. The ozone layer is depleting over time because of air pollution.

5. Too much nitrogen can be bad for the environment because there would be more nitrogen than oxygen which makes it harder to breathe.

6. The greenhouse effect is the trapping of heat from the sun.
