  • Section 2: Environmental and Medical Issues
    • 2.1 Global Warming
      • What is Global Warming?
        • The increase temperature of the Earth's atmosphere (thought to be caused by greenhouse effect)
        • The fact that the average temp of the Earth's surface is rising.
      • What makes it happen?
        • Human activities
          • Burning fossil fuels - coal, oil and gas. Increases CO2 in the atmosphere
          • Burning of fossil fuels produces CO2. Produces a barrier in the atmosphere like the glass in a greenhouse. Heat can get in but can't get out.
      • What can we do about it?
        • Using alternate forms of energy e.g. solar and wave power.
        • Increase use of public transport. e.g. trains and buses
        • Reducing electricity usage e.g. turning off lights.
        • Improve the efficiency of and reduce the pollution caused by cars e.g. Hybrid engines
    • 2.2 Forms of pollution and their possible solutions
      • Main types of pollution (PROBLEMS)
        • Acid Rain
          • Caused by burning fossil fuels, which releases sulphuric and nitric acid.
        • Human waste (litter)
          • Sewage and litter not only a form of pollution but also a major threat to the failure of the planet
        • Radio-active Pollution
          • Nuclear power stations don't produce CO2 but produce nuclear waste which will take thousands (if not millions) of yrs to be safe.
          • Human contact with too much radiation can  kill, give cancer + give genetically mutated kids.
        • Acid Rain
          • stop burning + using fossil fuels. Use more renewable energy
        • Human waste
          • Recycle more and burn the rubbish to provide fuel for power stations
        • Radio-active Pollutions
          • Some nuclear waste can be recycled. BUT the other 3% has to be stored somewhere safe in the long term
    • 2.3 The Scarcity of Natural resources
      • Renewable energy
        • Resources which humans can use over and over again e.g. solar power
      • Non-renewable energy
        • There are resources which disappear once they are used e.g. coal
      • Possible solutions
        • There are other ways to make electricity e.g. solar power
        • Recycling will enable a lifetime of finite resources to be extended. E.g. some cars are now made from 70% recycled material.
    • 2.4 Stewardship
      • The Creation story in Genesis
        • God gave humans the right to rule over Earth. Gives human control of animals and plants. Bible clearly says that, the right to rule gives human many responsibility
      • Teaching of Jesus
        • In many teachings especially the 'Sermon on the mount', Jesus taught that Christians have a responsibility to ensure a fair sharing of Earth's resources.
      • Judgement Day
        • Bible makes clear that there will be a judgement day. People will be judged on their beliefs + behaviour. Christians believe that part of judgement will be on how they fulfilled their duty as stewards
      • Teachings in Old Testament
        • Teaches that humans have responsibility to treat animals humanely and to treat the land kindly by not growing crops every fifth year
    • 2.5 Islamic teachings on Stewardship
      • Meaning: Looking after something so it can be passed on to the next generation
      • The responsibility to be God's khalifah means that Muslims should try to reduce pollution and preserve resources by following Shari'ah law
      • There is a unity + balance in creation, therefore Muslims have a duty to preserve the environment and make sure that it continues to be what God intended it to be.
