7. BIODIVERSITY makes ecosystems more _______ Ecosystems with
_____ biodiversity are better able to resist ____________ such as species loss, pollution, invasive species, urban development, climate change, etc.

8. VOCAB Species that has died out = ______________
Species that has died out = ______________

becoming endangered in
the near future = ____________

9. The Tragedy of the Commons
When a resource (like the environment) is shared, everyone can use it but NO ONE IS RESPONSIBLE FOR PROTECTING IT.
Each person just uses “a little”, but it often results in the destruction of the “commons”.

15. BIODIVERSITY THREAT
Splitting a habitat into smaller disconnected pieces = _____________________
Small “islands” of natural
area isolated from each
other.
Brings wildlife into
contact with humans

16. HOW CAN WE HELP? PRESERVES/SANCTUARIES
Preserving habitat
Establishing protected areas
Game ranger patrols to prevent poaching
Education

17. HOW CAN WE HELP? ___________________
Animals are raised and protected in zoos until population is stable, then returned to wild

18. HOW CAN WE HELP? LAWS/REGULATIONS
Convention for the Regulation of Whaling 
- International Whaling Commission has
placed a moratorium on whaling for certain species
-Only works if nations voluntarily comply

19. LAWS & REGULATIONS
The________________________________________________________ (CITES)
bans international trade in products
from endangered species.

20. WHAT CAN WE DO TO HELP?
Support “Green” organizations that work for laws to establish quotas and protect species.
