IB Environmental Systems what are the causes of environmental pollution ess & Societies Applying the Pollution Management Model

Here are the suggested answers to the review exercise on the pollution management model Applying the Pollution Management Model .
Regulation of emissions through scrubbers and catalytic converters on chimney stacks
legislation on recyclability of packaging
Legislation on compulsory fitting of catalytic converters to cars
We regret that our free trials are only available for IB schools.
Campaigns to reduce use of fossil fuels.
campaigns / education to reduce use and control timing of artificial fertilisers by farmers / golf courses / gardeners
Removing mud and silt from water bodies through dredging
Regulations on total SOx and NOx emissions
Change the human activity that leads to the production of the pollutant in the first place, by promoting alternative technologies, lifestyles and values through:
Reverse osmosis to extract toxins from water
Our teacher sites include INTEGRATED STUDENT ACCESS which enables you to set tasks and give feedback online. Student access is easy to set up; you can set reading, writing, discussion, and multiple choice tasks; and you can track student progress.
campaigns / education to change to detergents without phosphates

Legislation for standards from water treatment plants
trading system for pollution in NOx or SOx
Website by Zoe Badcock & Laura Hamilton
campaigns on bringing reusable shopping bags

Taxes on pollution e.g. trading of sulfur emissions in US
Clean-up and restoration of damaged systems
Sieves/Nets on storm drains to prevent plastic pollution entering waterways.
Systems to remove plastics from Great Pacific Garbage patch
Where the activity/production is not completely stopped, strategies can be applied at the level of regulating or preventing the release of pollutants by:
Clean-up and restoration of damaged systems
legislation on how waste must be treated, e. what are the causes of environmental pollution ess g. no landfill
reducing food waste through planning of meals and shopping
Fitting spinkler systems at busy road junctions to "wash" pollution out of air
Where both the above levels of management have failed, strategies may be introduced to recover damaged ecosystems by:

Legislation on release of pollutants, e.g. NOx or SOx, from chimney stacks and car exhausts
Spreading limestone on land or in acidified lakes
Clean-up and restoration of damaged systems
Legislation about need for levels of phosphates and nitrates and toxins allowed to be deposited in public water ways.

Clean-up and restoration of damaged systems
technological development to extract all valuable materials from waste stream e.g. magnets, water treatment, electrostatic precipitators
Here are some suggested answers for managing pollution. If you chose to write an essay question which used these responses, you would need to expand on your points and explain any examples and case studies that you use. You probably will also have to evaluate the strategies or look at them through an EVS lens.
Campaigns about danger of acid rain on ecosystems
