DP Environmental Systems and Societies Questionbank

To what extent is pollution impacting human food production systems?

Describe two strategies for the management of sustainable capture fisheries.

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

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

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.

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

Outline why estuaries are highly productive ecosystems.

Discuss with reasons or evidence, the environmental impacts of two named food production systems.

Including reference to their relative efficiency, discuss whether terrestrial or aquatic food production systems show the greatest potential for feeding a growing human population. Support your conclusion with valid reasons or evidence.

Discuss the relationship between social systems and food production systems with the help of named examples.

Discuss the relationship between the economic development of countries and the sustainability of their food production.

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

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.

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 the harvesting of a named aquatic species may be controversial.

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

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

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

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?

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

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

Outline one reason why aquaculture production has increased globally.
