Why we need to plant trees?

• ·         Trees filter our air and keep it fresh by absorbing carbon dioxide and producing oxygen.
• ·         Tree roots stabilize the soil and prevent erosion.
• ·         Trees improve water quality by slowing and filtering rain water as well as protect aquifers and watersheds.
• ·         Trees are carbon sinks, accumulating carbon as they grow and acting as stable carbon stores upon maturity
• ·         Three-quarters of the world's people rely on wood as their main source of energy.
• ·         Thousand of things are made from trees such as furniture, books, newspapers, houses, hockey sticks, guitars, pencils, fences, milk cartons, even nail polish and toothpaste.
• ·         Trees lower air temperature and induce rainfall by evaporating water from their leaves.
• ·         Trees provide food, shade and shelter to humans and wildlife.
• ·         Trees offer protection from the downward fall of rain, sleet and hail as well as reduce storm run-off and the possibility of flooding.
• ·         Trees act as sound barriers to reduce noise pollution.
• ·         Trees play a major role in helping to conserve the intensity of the Earth's magnetic field.
• ·         Trees beautify the landscape.
• ·         There are about 20,000 tree species in the world. India has one of the largest tree treasuries in the world followed by the US.
• ·         No tree dies of old age. They are generally killed by insects, disease or by people. California Bristlecone Pines and Giant Sequoias are regarded as the oldest trees and have been known to live 4,000 to 5,000 years.
• ·         Trees grow from the top, not from the bottom as is commonly believed.
• ·         Trees receive an estimated 90% of their nutrition from the atmosphere and only 10% from the soil.
• ·         About one-half the weight of dry wood is carbon.
• ·         In ancient Mesopotamia (now Iraq), the value of wood was equal to that of precious gemstones and metals.
• ·         Rome’s monetary system was based on silver which required huge quantities of wood to convert ore into metal.
• ·         Dendrochronology is the science of calculating a tree's age by its rings.
• ·         Tree rings provide precise information about environmental events, including volcanic eruptions.
