DeforestationSpec 4.7.3.4

Large-scale deforestation in tropical areas has occurred to:

  • provide land for cattle and rice fields
  • grow crops for biofuels.
Environmental implications of deforestation
ImplicationWhy
Loss of biodiversityThe habitat is destroyed, so many species lose their food and shelter and die out
More carbon dioxide in the atmosphereFewer trees means less photosynthesis, so less carbon dioxide is removed. Decay and burning of the trees release carbon dioxide
Contribution to global warmingHigher carbon dioxide levels contribute to global warming

Cleared land can provide food and fuel crops, so there is a conflict between the economic needs of people and protecting the environment.
