Just plain AWESOMENESS
Homes for wildlife, recreation,
inspiration
The ability of ecosystems to provide these
services depends on BIOLOGICAL

The Tragedy of the Commons
• http://www.youtube.com/watch?v=EZFkUeleHPY
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”.

REMEMBER
A ____________ is anything an
organism needs for life
NATURAL RESOURCES =
LAND
AIR
WATER

_____________________ can’t be
replenished by natural processes
EX: copper, gold, fossil fuels, rainforests
________________ can be replenished
- living by reproduction
- nonliving by biogeochemical cycles
EX: fish, tree, soil
____________________________
replenished but used faster than can be
replaced
EX: water

BIODIVERSITY THREAT
Splitting a habitat into smaller disconnected
pieces = _____________________
Small “islands” of natural
area isolated from each
other.
Brings wildlife into
contact with humans
http://en.wikipedia.org/wiki/Habitat_fragmentation
HOW CAN WE HELP?
PRESERVES/SANCTUARIES
Preserving habitat
Establishing protected areas
Game ranger patrols to prevent poaching

HOW CAN WE HELP?

Animals are raised and protected
in zoos until population is stable,
then returned to wild

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
http://www.cdnn.info/eco/whaling_250146.jpg
LAWS & REGULATIONS
The_______________________________
_________________________ (CITES)
bans international trade in products
from endangered species.
http://www.mtholyoke.edu/~sjberg/CITES.htm
WHAT CAN WE DO TO HELP?
Support “Green” organizations that work
for laws to establish quotas and protect
species.

Scientists estimate there are 10-30 million
plant and animal species on the planet
Most of these are unidentified.
Some scientists estimate
at the rate we are going
___ of the plants and animals
will be committed to extinction by 2050
http://www.igreens.org.uk/extinctions_predicted_from_globa.html
International Union for Conservation of
Nature ( IUCN) RED LIST
= world's main authority on the
conservation status of species
22,214 threatened species worldwide
AND NUMBERS ARE INCREASING!
2012 - 3079 animals and 2655 plants
classified as Endangered worldwide
1998- 1102 animals and 1197 plants
classified as Endangered worldwide
•http://www.whole-systems.org/Resources/Image10.
It is believed that some 10,000 species have
gone extinct in just the past 100 years
At current rate estimates predict between
200-2000 extinctions per year.
