world?

16.5 CONSERVATION
KEY CONCEPT
Conservation methods can help protect and restore
ecosystems!!!!
SCORE Oyster
restoration!!!
Sustainable development: management of
resources for present and future generations!!!!
• Managing & using resources
WISELY!
– meet current needs
– resources will still be
available for future use
Industries involved: Timber, fishing,
agriculture, development!
• Global fisheries have adopted several sustainable
practices, 70% of fisheries in danger!!!
rotation of catches:
fishing gear review:
harvest reduction:
fishing bans:
Technology – good and bad!!
Pros
•Benefits to mankind
•Communication
•Medical advances
•Scientific research
Cons
•Pollution of air, water,
etc.
•Use of resources
•Habitat destruction
•Excess waste generated
Agricultural Technology:
•Crops: bigger, better, less erosion
• GOOD
•Farm machinery
• uses non-renewable resources
• BAD
•Ag. runoff & chemicals
• more fertilizers & pesticides!
• BAD
Industrial Technology
•Chemicals(CFCs)
•deplete ozone layer
•BAD
•Old equipment
•what do we do with it????
•BAD?
•Fossil fuels
•increased greenhouse gases, global
temp (BAD)
•Acid rain: ecosystem harm!!! (BAD)
Alternative Energy
•Natural renewable energy: GOOD!
• wind, water, solar!
• Decreases f.f. burning, less pollution!!
•Nuclear energy technology:
• no atmospheric pollution, but toxic waste
• Hmmm…
Conservation practices benefit entire ecosystems
– “listed” species (in
trouble)
• IUCN website
» Threatened,
endangered, etc.
– habitat is protected
– other species
protected in the
ecosystem
Protecting Earth’s resources helps
protect our future!
• U.S. Environmental Protection Agency (EPA)
– created in 1970
– develops policies, regulations to protect envt.
– Clean Air Act
– Clean Water Act
– Endangered Species Act
• protects individual species from extinction
What can we do?????
1. The National Park Service
helps manage public lands.
The park system
includes over 390
areas, covering
84 million acres!!
Go Visit Your Parks!!!
What else can we do?????
– control population growth
– develop sustainable technology and practices
– protect and maintain ecosystems
Review!!
– What is sustainability?
– What are some industries
practicing sustainably?
– What is the fishing industry
doing???
– How can advances in technology
help and hurt the environment???
Review!!
– What are some pros and cons of
agricultural technology?
– What are some pro’s and con’s of
industrial technology?
– What are some pro’s and con’s of
alternative energy??
– What is an umbrella species?
– What else is protected when a
species “gets listed”??
Save the Earth Tree
• On your “leaf” card, write ONE tip
for ORDINARY PEOPLE…LIKE
STUDENTS AND TEACHERS…to
help save the planet
• We’ll make a TREE full of tips!
The Story of Stuff
• Jot down some notes during the
video so we can talk about it
after…things when you’re like
