|
|
What triggered the MOdern Environmental Movement?
2 main movements -- summarize how they differ? |
First Wave (1968-76)
- Issues: pollution, energy crisis, offshore oil drilling and spills, nuclear power, resource depletion, urban lifestyles - Characteristics: anti-technoloyg, escapist, regulatory, increase awareness of envrionmental problems Second Wave (1985-present) - Issues: ozone depletion, globabl warming, oil spills, hazardous waste, pollution, habitat concerns, resource depletion, urban planning, indoor air quality, waste reduction and recycling Characteristics: preservation, global perspective, politicians and economists accept environmentalism, professional environmental organizations, large split between compromisers and opposers, use many tools to accomplish goals |

Paradigm Shift - what is it
Some believe we are in a PS in regards to the environment. Is this true, what indications? |

|
|
Two root causes of global environmental problems
|
Population -- continually growing at an exponential rate, too many people for the resources we have
Consumption --- we use more than we need |
|
|
Our main environmental problems are:
|
- overpopulation
- resource depletion - pollution - reduction in biodiversity |
|
|
What happens when populations increase??
|
- deplete and damage resources
- results in pollution, reduced biodiversity,e extinction's |
|
|
What are natural resources, renewable resources, and non renewable resources?
|
Non renewable resources: cannot be replaced - oil, natural gas
Renewable resources: can be replaced (sun, resources from living organisms) Natural resources: water, air, soil, minerals, fossil fuels, plants animals |
|
|
pollution- What is being polluted? how is it occurring?
Difference between point and non point pollution |
Occurs in air, water
Happens through global warming and ozone depletion, acid rain Point pollution: know the source (oil tanker) Non point pollution: many small sources produce a big problem (oil or gas leaking from cars) |
|
|
Reduction in biodiversity
Why is it a concern? What are COSEWIC and SARA |
Rate of extinction has grown with human activity
- all life is connected -- what happens to one species affects 1000' s of other species Species at Risk Act Committee on Status of Endangered Wildlife in Canada |
|
|
Explain
Extinct Endangered Extirpated Threatened Special Concern |
Extinct - no longer exists
Endangered - high risk of extinction Extirpated - species leaves an area due to overpopulation (local extinction Threatened - likely to be endangered in near future Special Concern - population numbers are of concern |
