• What effect does the destruction of peat bogs, and other areas of peat to produce garden compost have?

  Reduces the area of this habitat and therefore reduces the variety of different plant, animal and microorganism species that live there (biodiversity)
• What does decaying or burning peat release into the atmosphere?

  Carbon dioxide
• Large-scale deforestation in tropical areas has occurred to:

  • Provide land for cattle and rice fields
  • Grow crops for biofuels
• What are some factors that can lead to global warming?

  • Levels of carbon dioxide increasing
  • Levels of methane increasing
• What programmes have scientists and concerned citizens put in place to reduce the negative effects of humans on ecosystems and biodiversity?

  • Breeding programmes for endangered species
  • Protection and regeneration of rare habitats
  • Reduction of deforestation and carbon dioxide emissions by some governments
• What are 3 consequences of global warming?

  • Weather patterns will change with more unusual weather
  • Animals will migrate towards the poles to find habitats with suitable temperatures
  • Tropical diseases may become more common in other regions, such as Europe
