deforestation and land use

• What is considered the most important limited resource for humans?

  Land
• What are some uses of land by humans?

  Building, farming, quarrying, dumping waste
• What is the consequence of using more land for human activities?

  Less land available for other organisms
• What are the knock-on effects of converting land?

  It damages the environment further
• What are the consequences of converting forests and destroying peat bogs?

  • Deforestation leads to loss of photosynthesis
  • Increased carbon dioxide contributes to global warming
  • Habitat destruction reduces biodiversity
• What is the term for cutting down forests?

  Deforestation
• What is the main reason for deforestation?

  Clearing land for farming
• What is one use of land cleared from forests?

  Raising cattle
• What are biofuels made from?

  Plant-based materials
• What is logging?

  Clearing forests for wood
• Where is deforestation currently happening a lot?

  Tropical regions with rainforests
• What are the three main problems caused by deforestation?

  1. Loss of trees reduces carbon dioxide absorption
  2. Burning forests releases stored carbon
  3. Habitat destruction leads to reduced biodiversity
• How does deforestation contribute to global warming?

  It increases carbon dioxide in the atmosphere
• What happens when forests are burned during clearing?

  They release carbon as carbon dioxide
• What is the impact of habitat destruction on biodiversity?

  It massively reduces biodiversity
• What are peat bogs?

  Acidic and waterlogged areas of land
• Why can't microorganisms decay plants in peat bogs?

  Too acidic and waterlogged conditions
• What substance is formed from partially rotted plants in peat bogs?

  Peat
• How does peat help reduce global warming?

  It stores carbon instead of releasing it
• What happens when peat bogs are drained?

  Microorganisms decompose dead plants, releasing carbon
• What is one use of peat when removed from bogs?

  Burning as fuel
• What is the consequence of destroying peat bogs?

  Release of carbon dioxide into the atmosphere
• How quickly is the destruction of peat bogs occurring?

  Much faster than new ones can form
• What are the effects of destroying peat bogs on biodiversity?

  • Reduces habitats for organisms
  • May lead to extinction of species
