6
Sustainability

• In a sustainable ecosystem
• changes that occur dont cause negative long-term
  impacts to any organisms or part of the ecosystem

7
Non-sustainable practices

• When human activities (e.g., clear cutting, over
  fishing, etc) impact a part of the environment or
  ecosystem, without allowing it to recover (e.g.,
  replanting trees, limiting the number of fish
  harvested) the system will collapse.

Task 1

• Worksheet

13

• Many people would say that we are in the midst of
  paradigm shift today with regard to how we think
  about the environment.

14
Task 2

• What evidence is there to support this belief?
  What impact would this shift have on the planet
  in general and Nova Scotians in particular? Why
  might people not want to make this shift?
• Rubric
• Evidence to support this belief /2
• Impact shift would have on planet /2
• Impact shift would have on Nova Scotians /2
• Why people might not want to make this shift /2
