DP Environmental Systems and Societies Questionbank

Outline, using examples, the differences between primary and secondary pollution.

With reference to information in the resource booklet, evaluate the sustainability of Canada’s management of the Large Ocean Management Area of the St Lawrence River estuary and Gulf of St Lawrence.

With reference to Figure 9(a), outline how the round goby both positively and negatively affects the St Lawrence River ecosystem.

Explain how three pollution management strategies may reduce eutrophication in agricultural areas.

Pollution management strategies may be applied at any of the three levels identified in the diagram below:

With reference to acid deposition, evaluate the political and economic advantages of applying management strategies at the levels of production and impact of the pollutant.

Define the term pollution.

Outline two indirect methods that could be used to measure the impact on the river ecosystem of dead organic matter from the flooded vegetation and soils.

Identify one possible pollution management strategy for Inle Lake in each of the categories in the table below.

With reference to Figures 4 and 5, complete the following table.

With reference to Figures 4 and 5, identify three environmental impacts that may occur as a consequence of human activities on and around Inle Lake.

Discuss how different environmental philosophies can affect the choice of pollution management strategies in response to global warming.

Nitrates and phosphates from nearby farms may drain into the lake. Identify a strategy for managing this pollution at each of the following levels:

A non-governmental organization has been contracted to investigate the impacts of a landfill site on the surrounding terrestrial ecosystem.

Suggest how the investigation should be designed to ensure reliability and validity.

Evaluate one possible pollution management strategy for solid domestic waste.

Explain two factors which lead to a loss of marine (ocean) biodiversity.

Justify whether or not Mesquite should be cleared from the Swakop River Valley.

Outline why point source pollution is often easier to manage than non-point source pollution.

With reference to data throughout the resource booklet, to what extent would the establishment of Marine Protected Areas (MPAs) benefit marine ecosystems and human societies within the Coral Triangle?

Urban air pollution can become a problem as human populations develop. Evaluate urban air pollution management strategies at the three levels of intervention.

The management of a resource can impact the production of solid domestic waste.

To what extent have the three levels of the pollution management model been successfully applied to the management of solid domestic waste?

To what extent might Iceland be viewed as a role model for sustainability by other countries?

With reference to Figures 6(c), 7(a) and 7(b) explain the problems associated with land restoration in Iceland.

With reference to named examples, distinguish between a primary and secondary pollutant.

The provision of food resources and assimilation of wastes are two key factors of the environment that determine its carrying capacity for a given species.

To what extent does the human production of food and waste each influence the carrying capacity for human populations?

Pollution management strategies may be aimed at either preventing the production of pollutants or limiting their release into ecosystems.

With reference to either acid deposition or eutrophication, evaluate the relative efficiency of these two approaches to management.
