Key Questions:

1. How can an increase in human population affect pollution?
   • Rapid growth in the human population and an increase in the standard of living mean that increasingly more resources are used and more waste is produced. Unless waste and chemical materials are properly handled, more pollution will be caused.
2. Where can pollution occur and what does it occur from?
   • Pollution can occur: - in water, from sewage, fertiliser or toxic chemicals - in air, from smoke and acidic gases - on land, from landfill and from toxic chemicals.
3. How can pollution affect biodiversity?
   • Pollution kills plants and animals which can reduce biodiversity.
4. What are the environmental implications of deforestation?
   • Deforestation vastly affects the environment as well as reducing biodiversity. This occurs due to forest habitats being destroyed, soil erosion increasing, which causes barren land, flooding and land slides. Also atmospheric pollution is caused when forests are cleared by burning trees increasing global warming.
5. What are the biological consequences of global warming?
   • A rise of just a few degrees in world temperatures will have a dramatic impact on the climate: Global weather patterns will change, causing drought in some places and flooding in others. Melting of polar ice caps will raise sea levels, causing increased coastal erosion and flooding of low-lying land – including land where major cities lie.
6. Why is global warming increasing?
   • Levels of carbon dioxide and methane in the atmosphere are increasing, and these contribute to global warming.
7. What does the scientific consensus say about global warming and climate change?
   • The scientific consensus about global warming and climate change is based on systematic reviews of thousands of peer reviewed publications.
