Practise IB ESS HL 006.002.009 by applying perspectives on climate change concepts to environmental systems questions.
Three levels of pollution management strategies diagram
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.
Level of "producing". Award [1 max] for outlining such management: relevant to acid rain:
Eg management can be applied at level of producing by reducing use of fossil fuels/ switching to alternative energy sources;
political advantages/disadvantages:
it may not be popular to impose limits on use of fossil fuels in certain societies;
but it does address root cause of problem;
and political factors have the advantage of generating laws/incentives;
in democratic societies such management may have strong influence on voting/political support;
may gain international support for an issue that often crosses national boundaries;
economic advantages/disadvantages:
it may be very costly to switch to alternative energy sources;
could be long-term economic benefit in this for countries importing fuel;
would be economically beneficial in context of international C-trading;
may gain volunteer support from community/NGOs that make management more cost effective;
Level of "impact". Award [1 max] for outlining such management:
Eg. management can be applied at level of impact by liming of water bodies/ restoration of natural communities;
political advantages/disadvantages:
it may be popular because it allows use of fossil fuels to continue;
and restores aesthetic qualities of environment;
but may conflict with the increasing "green"/ecocentric sector of many societies;
economic advantages/disadvantages: avoids cost of switching from fossil fuel technologies;
liming and restoration may be very costly;
could be mitigating benefits eg sustainable goods/services of restored systems;
provides for environmental projects attractive to local community/NGO voluntary support;
Alternative points of equivalent validity, significance and relevance to those given, should be credited.
Marking guidance:
Award [5 max] for responses that address only one level of management, or only political, or only economic, factors.
