- 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.
- Human activities
- 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
- What is Global Warming?
- 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
- SOLUTIONS
- 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
- Acid Rain
- Main types of pollution (PROBLEMS)
- 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.
- Renewable energy
- 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
- The Creation story in Genesis
- 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.
