Catalyst
1. Provide one example of how a pollutant could affect life on land AND in water
2. What happens to the amount of pollution as you travel up a food chain? Why is this significant?
3. What is the difference between Cap and Trade and Command and Control?
Objectives
By the end of today, all SWBAT…
• Describe the difference between conservation and preservation models
• Explain the advantages and disadvantages of the zoo model
Conservation vs. PreservationConservation Preservation
Goal Save species Save species
Definition Humans protect species while benefitting from them
“Hands on”
Saving species in their original state
“Hands off”
Humans? Yes No
Advantages Humans benefit Humans don’t impact animals
Disadvantages Animals don’t live a “regular life”
Humans don’t benefit
Hard to get money to fund
Key Point #2Zoos have many purposes
Provide entertainment Conserve species Educate people about animals
Pros (+) Teach children to value animals
Keep animals safe Breeding programs increase population sizes
Cons (-) No zoo has saved a species from extinction
Poor treatment of animals Take out of native environment Animals develop odd behavior
Debate…FOR or AGAINST zoos
A California zoo decided to aid in conservation of the animal by adding two polar bears to its exhibit. Unfortunately, the climate is much different in California than the arctic tundra.
As a result, the polar bears react oddly to the temperature difference. The two bears swim laps in the small pool in their exhibit all day to keep cool. Additionally, the pool is not large enough for both polar bears at the same time.
Debate…FOR or AGAINST zoos
Unfortunately, some zoos in third-world countries do not have strict laws regarding animal care and do not properly care for their animals.
The Ragunan Zoo in Indonesia received many complaints that there was trash in many of the animal exhibits. Shortly after these complaints, an orangutan died from a plastic bag that got stuck in its digestive tract.

The Palm Beach Zoo spends thousands of dollars every year in breeding programs. Five jaguar cubs have been born at this zoo. Additionally, the jaguar is a solitary animal (lives alone). Therefore, populations of jaguars require atleast 3 acres of space (a large amount) to survive in the wild. However, the jaguar exhibit in the Palm Beach zoo places two jaguars in an area of ½ acre.
