  • Pollution Management
    • human causes: farming, industrial practices, urbanization, development of transport, energy resources.
    • Changing human activites
      • education, incentives & penalties
        • Develop alternative technology
          • Expensive and may only work in certain environments
        • reduce, reuse, recycle
          • Some goods only recyclable under special conditions or can be hazardous (e.g. e-waste in electronics)
            • E-waste management:E.g. Dell cover costs to the recycling centre. These helps reduce the volume of waste in landfills, reduce raw materials needed for new products and make recycling convenient for the consumer
        • Adoption of alternative lifestyles
      • Using renewable sources reduce greenhouse gas emissions
    • Regulating or reducing pollutants released
      • Measures for extracting pollutant from waste emissions
        • Flue gas desulfurization (FGD) control emissions of SO2 from coal & oil power stations
          • The treatment (FGT) remove pollutants from waste incinerators. However they're expensive and difficult to enforce every source of pollution.
    • Cleaning up and restoring the ecosystem after pollution has occurred
      • Replanting and restocking with animal populations
      • Expensive in terms of labour, time & money)
      • Bacteria take time to break down pollutants before recovery through 2nd succession (takes longer in cold conditions).
