Evaluate a strategy to manage the effects of one pollutant named in Figureor Figure.
Example NOx/SO2 : replacing use of fossil fuels with alternative energy sources;
Advantage: it eliminates emission of pollutants altogether;
Disadvantage: it would involve major social changes that may be unpopular;
Appraisal: could be successful in a society that has strong ecocentric principles;
Example NOx: use of catalytic converters to trap emissions;
Advantage: would enable continued use of fossil fuels appropriate to popular technology;
Disadvantage: allows continued emission of other pollutants e.g. CO2/hydrocarbons;
Appraisal: would be relatively easy to introduce and enforce in a society;
Example NOx/SO2 : clean-up of acidified aquatic ecosystems using lime;
Advantage: relatively easy to apply / no requirement for popular cooperation;
Disadvantage: expensive and short term solution;
Appraisal: in the long run it would be better to remove root cause
Note: Allow 1 max for each valid e.g./advantage/disadvantage/appraisal up to 3 max.
