1. Environmental Health Why do we care?
What are the long term impacts of waste and overuse?
What are the causes of pollution?
Does the earth have unlimited resources?
What about Population and the earth’s resource
How much do certain societies use…re-use things- disposable coffee cups, throwing away plastic bottles, throwing away glass jars, wasteful

2. Population growth Graph of population growth?
Population and increase in CO2 levels in air
Co2 levels in air increase global warming
Trees use CO2
People use more resources…need more food stress the ecosystem to provide resources
US is greed with resources… re-use things like bags and glass containers, plastic containers
Producing these things needs power

3. Climate change Is the earth getting hotter of colder Past ice ages
Past hot times

4. Climate change Paleocene-Eocene Thermal Maximum
During the PETM, the global mean temperature seems to have risen by as much as 5-8 °C (9-14 °F) to an average temperature as high as 23 °C (73 °F), in contrast to the global average temperature of today at just under 15 °C (60 °F). Geologists and paleontologists think that during much of the Paleocene and early Eocene, the poles were free of ice caps, and palm trees and crocodiles lived above the Arctic Circle, while much of the continental United States had a sub-tropical environment.[5]

5. Climate change
Ice age
However, other evidence suggests that the period of 2,000 to 3,000 million years ago was very generally colder and more glaciated than the last 500 million years.[citation needed] This is thought to be the result of solar radiation approximately 20% lower than today. Solar luminositywas 30% dimmer when the Earth formed 4.5 billion years ago,[13] and it is expected to increase in luminosity approximately 10% per billion years in the future.[14]

6. recycling Colorado… hard to find it
California is probably one of the more advanced states in terms of this
Composting
Salt in food
Salt and sugar are preservatives…
Why honey/sugar doesn’t go bad
Why a jar of salt doesn’t go bad

7. Air quality Coal Air pollution from cars India China
Los angeles in the 70s
After the fires

8. Air quality Cars Fossil fuels or energy Factories
Air pollution into plastic
Fire air quality
Air quality in china (factory emissions)
In in the boxes you open
Air quality in india ( burning fields)

9. Hybrid and electric cars
Hybrid cars are designed to use less energy and reduce emission

10. Nuclear Power Chernobyl
accident/
Fukushima
Bodega Bay

11. Wind power Using natural resources that are wasted to create energy.
Look to boats and other ”off the grid” situations to see what works
Boat that was stuck… had a water purifier, and dry food to last 1 year oatmeal, beans, rice

12. Solar power Solar energy a clean source of power. Watches Calculators
Security systems
Houses

13. Hydroelectric/water management
Power source
Water management ( San Jose flood)
Drought of the past few years
Water storage

14. Desalinazation of water
Water FX
Huge need for water because of agriculture ( we are the bread basket of America)
Need for water because of people
Mulhulland and the Owens Valley and fights over water for Los Angeles
Los Angeles is basically a desert ( less than 15 inches of water a year)

15. Seeding the clouds

16. Organic food
Pestiticides can make food last longer but can also increase risks of cancer
