STRIP MINING - completely removing earth’s surface to access minerals & coal
Main Idea
CONSTRUCTION – large scale projects (highways) destroying an ecosystem completely
WAR – bombs and moving heavy equipment (tanks, etc) over terrain destroys ecosystem
ACCIDENTS – events like oil tankers sinking & nuclear power plant “melt-downs”
2Sudden Catastrophic ImpactQuickly & obliviously damaging an ecosystem to the point that it can never be restored
Human Negative Impact in the Ecosystem
Is about …
How people’s behavior impact the environment in bad ways
Main Idea
FERTILIZERS / PESTICIDES kill a variety of animals & plants; leave chemicals
POLLUTION / ACID RAIN waste products that kill organisms & break food chains
CONSUMING RESOURCES uses up things needed to maintain an ecosystem (i.e., minerals in soil)
1Slow Subtle ImpactSlowly and not obliviously damaging an ecosystem to the point that it can never be restored

Key Topicis about... exploitation
taking advantage of something or someone
Does this help or hurt in the real world?
What are some ways this idea shows up in the real world?
Personal experiences related to this concept
Takes advantage of people in a weaker position
Bad idea that should not show up
Quality of society based on how you help, not on much you can take
Exploitation results in anger
College make millions from games, but players can’t get paid
Politicians exploiting voters
Porn & prostitution exploits poor women
Some factories exploit workers
Parents exploit me when they make me do chores.
Kids in lunch room get exploited by bullies
Used car salesmen exploit buyers (if they can)
Casinos exploit poor people who wish to get rich quick
Our world would be a lot better off if there were no exploitation in it.

Cutting down Rain forests
is about the clearing of vast areas of rain forests to make grazing lands for cattle
I believed that it didn't matter where beef came from, as long as I could buy a 'Big Mac' when I wanted for a cheap price.
I now believe that we need cut down on how much beef we eat because of what is happening to rain forests.
Brazilians are cutting down rain forests as quickly as they can to... * create jobs & income * make grazing land for cattle so they can sell beef to US * sell trees
Fast food companies are buying cheap beef from Brazil so they can make more money selling hamburgers
Eat more chicken! Boycott hamburger joints. Spread the word and encourage others to do the same. Learn more about how our everyday habits impact the environment in important ways

Brazil’s population explosion (need jobs & income!)
Limited resources & ways to make money
Access to media (TV) shows apparent wealth of rest of the world makes poor
Brazilians want “a piece of the economic pie”
Brazil’s poor economy / need for money
Foreign companies willing to pay $$$ for beef & wood (teak, mahogany, lumber)
Cutting down rain forests as fast as possible to make grazing land for cattle & to sell trees for lumber
New source of income making some Brazilians rich...provides many
temporary jobs
Thin top soil washing away because loss of rain forest root systems, results in desert
like conditions where little will grow
Because of lost ecosystems, many animals & plants rapidly becoming
extinct - lost opportunity for develop of new medicines?
Loss of vast areas of vegetation results in less oxygen in atmosphere, & more carbon dioxide ...global warming?
Must generate alternative source of income for Brazilians, or they won’t stop clearing rain forests -- what would be other ways for them to make
money & generate jobs?
US Fast-food companies contract
for beef imports

(also called ‘air,’ comes from Greek word atmos (vapor) and shaira (sphere)
Troposphere
The layer we live in
Where all life occurs
80% of the mass of atmosphere
all moisture is here jet streams occur in this layer
Stratosphere moistureless & cloudless very low atmosphere density
no storms
ozone in this layer
Mesophere

very thin air

How beach development is endangering sea turtles
Turtles bury eggs in the sand
Sea Turtles crawl onto beach and bury eggs
Attracted to movement & glimmer of light on water
Sun incubates eggs; baby turtles dig out of sand
Beach development & tourists
Houses & Hotels line the water front for thousands of miles
Baby turtles die
Babies get lost, disoriented
Crawl toward bright lights, away from sea
Eaten by predators & Dehydrated
IF we don't turn-off our lights at night THEN the Loggerhead may become extinct
Crawl toward light to get to the sea & swim away
Baby turtles attracted to bright lights
Street lights, Car lights, flashing signs, carnivals
Endangered Loggerheads
Tourists using the beaches
Beach buggies

Non-renewable Resources

oil, gasoline
How much longer will the oil supply last?
Will oil ever run out? What will we do?
We’ve already used up most of the oil in the US – have to buy it from Middle East
More oil we use, the more dependent we are on other countries for oil

Environmental Collapse
People wanting to get the most of their environment while ignoring what they are doing to it
The environment exists for our exploitation. Natural cycles of nature that makeup the environment will always exists, no matter how we interact with the environment.
Almost every aspect of our environment is showing signs of collapse. * water pollution poisoning oceans (killing reefs, poisoning fish, ect.) * air pollution, global warming
It’s not me -- it’s them! Somebody else has to do it. The earth is resilient. I’m too insignificant to make a difference.
Develop a new perspective -- rethink what we do for short-term gain to ensure long term stability.
Environment is affected on a macro-level (how industry impacts it) & and on a micro-level (how everyday behaviors like driving a car to work or using Styrofoam containers for hamburgers for 30 seconds impacts it

The Water Cycle
Condensation
Precipitation
Evaporationheavier water drops fall to the earth
tiny drops of condensed water grows until they get too heavy
types of precipitation = rain, snow, hail, sleet
rain gage is used to measure precipitation
occurs when liquid is heated by the air
molecules separate
molecules nearest water surface bounce away & move into the air
liquid -to- gas ORwater -to- vapor
occurs when gases are cooled
molecules crowd together (snuggle up)
molecules packed together so they take less space
gas can then change into a liquid
The water cycle is a 3-part process by which water enters and leaves the atmosphere. It is a continuous cycle.

How oil spills are cleaned up. Decomposition – dispersion – physical
removal
The huge oil tanker that sank in Alaska & caused a disaster
Physical removal – it’s a LOT of work, VERY difficult, & takes years
Decomposition – I don’t really understand the chemistry part of this
How they prevent oil spills – seems like sooner or later, oil tanker will sink
Visit the place where the oil tanker sank to see how it looks now
