-Drinking water can be poisoned
-Microbacteria in sewage spread infectious disease in aquatic life and humans
-Fishermen and the tourist industry, depending on clear water, suffer economic losses

50
Q

Give 6 ways water quality and pollution levels are managed in the UK:

A

-Legislation in the UK and EU means strict laws limit the amount and type of discharge factories and farms can put into rivers
-Education campaigns inform the public about what is appropriate and what not to dispose of in sewage systems
-Waste water treatment plants remove waste solids, bacteria, algae and chemicals so water is then safe for drinking
-Investing in sewers and water mains reduces overflow of current sewers, spills and accidents
-Pollution traps such as reed beds catch and filter out pollutants
-Green roofs on buildings filter out pollutants in rainwater, reduce flooding and combat climate change by absorbing CO2 from the atmosphere

67
Q

Give 2 economic issues regarding nuclear energy:

A

-Plants are expensive to build and decommission, but the raw material (uranium) is cheap as such small amounts are used
-Cost to transport and store nuclear waste is high

68
Q

Give 2 environmental issues regarding nuclear energy:

A

-Waste remain radioactive for over 100 years and has to be stored safely to avoid contamination
-Despite a good safety record, nuclear accidents release radiation into the atmosphere, which has long-term impacts on wildlife and people

69
Q

Give 4 economic issues regarding renewable energy sources:

A

-It has high set-up costs such as wind turbines and solar farms etc. Costs are higher in remote areas
-Biomass means land not used for food production may increase the cost of food
-Tourism declines as environments lose their visual appeal; results in job and income loss

70
Q

Give 5 environmental issues regarding renewable energy sources:

A

-Many renewables are considered ugly and ruin the views in both the countryside and on the coast
