  1. Trees By Bela Ronald and RachealCortner

  2. The Benefits of Trees • Oxygen to replace carbon dioxide (clean air) • Energy source: Fire, heat, food (fruit & nuts) etc. • Shade-Trees reduce UV-B exposure by about 50 percent • Building/prevent erosion • Shelter for animals

  3. Tragic Deforestation • Erosion & floods • Loss of habitat/extinct animals • Top soil removal (trees give nutrition to soil) • Underground aquifer’s water source stays on the top of the earth resulting in loss of fresh water. • More evaporation = loss of fish/streams • Smaller plants die from direct sunlight

  4. Trees Now • Cover about9.4% of the Earth's surface (or 30% of total land area) • Before it was 50% of total land area • 61 trees per person • Over 400 billion trees (2005)

  5. Trees in our future • Depleting with time • More people = less trees • Predicted 9.6 billion people in 2050 (36yrs from now) • A lot better now than in the past • New organizations help with tree loss • Encouraging others to protect trees/plant

  6. How to Help • Plant trees • Buy real Christmas trees preferably organic • Recycle/reuse • Use less plastics • No Styrofoam • Support National Forests • Support solar/wind/water power not burning of fossil fuels
