1. IMPACT OF HUMANS AND NATURE ON THE ENVIRONMENT AND ITS ECOSYSTEMS

2. ECOSYSTEMS: Who are the players?
Remember that there are BIOTIC and ABIOTIC components in an ecosystem
The BIOTIC components affect each other, and they affect the ABIOTIC components
The ABIOTIC components affect each other, and they affect the BIOTIC components

3. EXAMPLES OF ECOSYSTEMS:
A LOG
A FOREST

4. ECOSYSTEMS ARE ALWAYS CHANGING
HUMANS AFFECT THE BALANCE WITHIN ECOSYSTEMS
Biotic and Biotic relationships change
Biotic and Abiotic relationships change
Abiotic and Abiotic relationships change
NATURE AFFECTS THE BALANCE WITHIN ECOSYSTEMS

5. HOW DO OUR BUILDINGS/HOUSES AFFECT THE BALANCE WITHIN AN ECOSYSTEM?
BEFORE
AFTER

6. HOW DOES OUR TECHNOLOGY AFFECT THE BALANCE WITHIN AN ECOSYSTEM?

7. HOW DOES OUR WASTE AFFECT THE BALANCE WITHIN AN ECOSYSTEM?

8. HOW DOES NATURE AFFECT THE BALANCE WITHIN AN ECOSYSTEM
FOREST FIRES
DROUGHTS
INFESTATION OF
INVASIVE SPECIES
HURRICANES
ETC.

9. QUESTIONS TO ASK YOURSELF:
WHAT WAS THE ECOSYSTEM LIKE BEFORE?
WHAT IS THE ECOSYSTEM LIKE NOW? HAS THE BALANCE CHANGED?
ARE THERE TOO MANY OR TOO LITTLE OF ANY BIOTIC COMPONENTS?
ARE THERE TOO MANY OR TOO LITTLE OF ANY ABIOTIC COMPONENTS?
HAVE ANY OF THE BIOTIC OR ABIOTIC COMPONENTS BEEN ELIMINATED?
IF ANY OF THE BIOTIC OR ABIOTIC COMPONENTS HAVE MOVED TO ANOTHER ECOSYSTEM, WHAT WILL HAPPEN TO THE BALANCE WITHIN THAT ECOSYSTEM?
ARE THE CHANGES WITHIN THE ECOSYSTEM SUSTAINABLE (will it last)?
