    Tropical Rain Forest Tropical Rain Forest Presentation Transcript

    • Tropical rain forest BY :DENA GHAZI
    •  
    • Where we find them?
      • Technically, this type of forest can be defined as a forest in the tropics receiving 4-8 meters of rain each year . Tropical rainforests are found in Central and South America, Southeast Asia and islands near it, and West Africa . There are smaller rainforests in northern Australia and other small islands . All tropical rainforests are found along the equator where the temperatures and the humidity is always high, with the days being equal to the nights .
    •  
    • Important facts
      • Amazon rainforests produce about 40% of the world's oxygen
      • One in four pharmaceuticals comes from a plant in the tropical rainforests
      • 1400 rainforest plants are believed to offer cures for cancer
      • 40%of tropical rainforests have already been lost in Latin America and Southeast Asia

    • Rain forests are in risk..
      • Of all the world's forests, it is those in the tropics that face the greatest threat from mankind . Tropical rainforests are one of nature's treasures, and many of them are now at risk . We have already destroyed half of the world's original tropical rainforests ! Just in a few decades, we can possibly witness the complete elimination of the world's rainforests . The biodiversity of this biome is legendary -- this biome contains the largest biomass . Did you know that enough rainforests are being destroyed every minute to fill 50 football fields? We need to preserve these valuable resources because they are the lungs of our planet, and can possibly hold cures for many of our most deadly diseases . The tropical rainforests are a critical link in the ecological chains of our earth's biosphere .

    • Climate
      • Generally, there is a flow of air that comes from the poles of the Earth, towards the equator . These winds are filled with moisture and the intense heat that is located at the equator causes the moisture to rise, cool and then condense to create rain . This continuous cycle causes it to rain almost 24 hours a day around most of the tropical areas . In some regions there can be more than 15 feet of rain a year . There are one or more " dry " months in this tropical biome, however if one would visit they would see it still is astonishingly wet .
    • Nice facts
      • Despite covering only 2% of our planet's surface, over half of the earth's animal, insect species, and flora live there .
      • Within a four mile square area of a tropical rainforest, you would find :
      • Over 750 species of trees
      • different kinds of flowering plants 1500
      • species of mammals 125
      • species of birds 100
      • reptiles 100
      • amphibians 80
      • countless insects
      • species of butterflies 150
      • ** Only 1% of these species has ever been studied **
