Carbon

• Reducing human impacts

  Alternatives to Fossil Fuels

  • hydroelectric, wind, solar, biomass

  Ex. Costa Rica has 98% of their energy renewable for 8 years in a row
• Reducing human impacts

  Carbon Capture Storage

  • capture CO2 before it is released into the atmosphere from industrial and energy generation
  • stored underground as a liquid in porous rock

  Ex. North-East Scotland
• Reducing human impacts

  Afforestation

  • plant trees because photosynthesis removes CO2 from the atmosphere
  • This is slow
  • planting in areas where there wasn’t forest before

  Ex. Costa Rica
• Reducing human impacts

  Soil Organic Matter

  • dead organic matter made of carbon is in the soil
  • Adding manure and compost into the ground adds carbon
  • don’t let it decompose because aerobic respiration is faster so don’t drain the soil to keep it under water - no oxygen

  Ex. Anywhere
• Reducing human impacts

  Peat bogs

  • water logged soil where dead organic matter can’t decompose (preserved under ground. It is marsh, wet, plants,
  • conservation - not used as fuel or agriculture
  • contains twice as much carbon as all forests

  Ex. Farlington Marsh
• There is a positive correlation between time and CO2 levels.

  • Deforestation means less carbon is being removed in photosynthesis
  • Combustion of fossil fuels and trees releases stored carbon
  • Drainage of peat bogs means they can’t store the carbon as the organic matter starts to be aerobically decomposed
