  • What is Deforestation? the cutting down, burning and damaging of forests.
  • Causes of Deforestation
    • Humans cut down trees and use the land for farming or cattle grazing.
    • Trees are cut down to provide us with: fuel, wood, paper, chopsticks etc.
    • 50 million creatures live by trees. If we do not have trees, many animals may become extinct.
    Why Trees Matter?
    • For the indigenous people
    • who live in the forests, the
    • forest is their home, source
    • of food, shelter, nourishment,
    • recreation, culture, and
    • livelihood.
  • Why Trees Matter?
    • Trees improve the quality of air, regulate the Earth’s climate, prevent erosion and landslides.
    • Trees provide medicines and herbs.
  • Effects of Deforestation
    • Orangutan

    • Number left: between 20,000- 27,000 and it is dropping.
    • Its reproductive rate is very slow, possibly once every 8 to 9 years.
  • Effects of Deforestation
    • Bengal Tiger
    • Deforestation has forced much of the Bengal Tiger’s preys, such as deer, antelopes, buffalo etc. to leave the place.
    • Bengal Tiger’s main danger: Its habitat destruction through agricultural expansion, new roads and human settlements.
  • Deforestation presents multiple societal and environmental problems. The immediate and long-term consequences of global deforestation are almost certain to jeopardize life on Earth. Some of these consequences include: loss of biodiversity; the destruction of forest-based-societies; and climatic disruption.
  • If the current rate of deforestation continues, the world’s rainforests will disappear within 100 years – causing unknown effects on global climate and eliminating the majority of plant and animal species on earth! THE END
