DP Environmental Systems and Societies Questionbank

With reference to Figures 3(c) and 3(d), outline how Hurricane Maria has reduced Dominica’s food availability.

Compare and contrast the impact of two named food production systems on climate change.

When harvesting is limited to the sustainable yield, associated processes involved in a food production system may still make the production unsustainable.

In this context, to what extent can aquatic food production systems be truly sustainable?

To what extent can the different environmental value systems improve the sustainability of food production?

Identify four strategies that can be used in the sustainable management of wild fisheries.

With reference to named examples, discuss the significance of diversity in the sustainability of food production systems.

Describe two negative environmental impacts that may arise from integrated aquaculture.

Quantitative models are frequently constructed to show the flow of energy and cycling of matter in natural systems.

To what extent can these models be useful in assessing the sustainability of named food production systems?

Discuss the role of humans in the destabilization of ecological systems.

Outline one reason why aquaculture production has increased globally.

Discuss the consequences of changing global per capita meat consumption on the conservation of ecosystems and biodiversity.

Discuss strategies that can be used to improve the sustainability of food production systems.

Explain why this system may cause fewer environmental impacts than systems that farm only fish.

With reference to Figure 8(d) identify two factors which may account for the changes in total capture of Atlantic herring.

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

Explain why the harvesting of a named aquatic species may be controversial.

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?

Outline one advantage for local populations within the Coral Triangle in harvesting their food from the marine system.

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

Suggest why the St Lawrence River beluga whale population has not recovered despite being given protected status in 1983.

Using Figure 2, identify one reason for the trend shown in the curve for aquaculture.

Using Figure 2, identify one reason for the trend shown in the curve for capture fisheries.

Describe two strategies for the management of sustainable capture fisheries.

Outline why estuaries are highly productive ecosystems.

To what extent is pollution impacting human food production systems?

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.
