trees

Question
Dear Jim,can you tell me the benefit of trees to our environment,paticularly in relation to our forest plantations and native forest


Answer
The benefit is in the products received from the Forests.  

Food and Medicine: Trees produce fruit, nuts, and seeds for people, plus fodder for animals.  Wooded areas also generate valuable herbs -- 25% of prescription drugs worldwide come from medicinal plants.

Employment: Forestry is labor-intensive.  It creates jobs at a time of widespread unemployment.  Forest development is simple and cheap, requiring little imported fuel or machinery, key advantages for a land-locked country struggling to define itself as a new republic.



Environmental Benefits: Each tree is an environmental wonder, at work 24 hours a day to improve the neighborhood.  Besides regulating air temperature, trees clean the air, consuming carbon dioxide and producing the oxygen we need to survive.   Woods and forests support a wide variety of animals and plants, ensuring a diverse, robust environment.



 Each year, 1 mature, 30 foot tree gives a family of 4 enough oxygen for an entire day.

    That same tree can discharge up to 100 gallons of water out of the ground and into the air daily.



    One acre of young trees yearly meets the oxygen needs of 18 people.

    That same acre can absorb as much carbon dioxide as a car produces in 26,000 miles.



A tree shelter can cut noise pollution in half



    Each 100 foot width of trees can absorb 6 to 8 decibels of sound intensity.



    Busy highways can generate as much as 72 decibels of noise



Each time we plant a tree we reverse the harmful effects of global warming.



    One 70 year-old tree can absorb 3 tons (6,000 lbs) of carbon from the atmosphere
