Trees By Bela Ronald and Racheal Cortner

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

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

Washington/Pullman  12 million acres of forestland in the state  Approximately 8.4 billion trees  Pullman has a Christmas tree farm which recycles trees safely  Couple of Tree Nurseries (Pullman)  Hundreds in Washington  8 national forests most around 1 million acres some 2.5 million ,7z/data=!4m5!2m4!3m3!1stree+nurseries!2sWashington!3s0x5 485e5ffe7c3b0f9:0x c5ff3ba

Trees Now Overall  Cover about 9.4% 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)

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

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
