Key Questions:

1. What is a major cause of climate change?
   • An increase in average global temperature is a major cause of climate change.
2. Describe briefly four potential effects of global climate change
   • The potential effects of global climate change are rising sea levels, damage to ozone layer, increase earth temperature, polar ice caps melting, animals may become extinct, damage to coral reefs.
3. What are the scale, risk and environmental implications of global climate change.
   • Global scale with different affects in different regions. Risk to lost of home, crops, spread of disease, more extreme weather events such as hurricanes and flooding and species extinction.
4. What is a carbon footprint?
   • The carbon footprint is the total amount of carbon dioxide and other greenhouse gases emitted over the full life cycle of a product, service or event.
5. How can a carbon footprint be reduced?
   • The carbon footprint can be reduced by reducing emissions of carbon dioxide and methane.
6. What actions are required to reduce emissions of carbon dioxide and methane?
   • The main way to reduce emissions of carbon dioxide in the air is to burn less fossil fuels. Unfortunately, we depend on the burning of fossil fuels for heating, electricity generation and transport. If we are to burn less fossil fuels, we will need alternatives for these essential activities. Cattle farming produces a vast quantity of methane and therefore an effective way to reduce the emissions of methane would be o move away from a meat based diet towards a more plant based diet. This would also be a more effective use of land as the land used to produce cattle feed could be used to grow crops and vegetables.
