IMPORTANCE OF TREE : 

IMPORTANCE OF TREE

Importance of Trees : 

Importance of Trees Trees one an important part of the Biosphere that exists on earth.  They play an essential part in the life of man.  Children play under them, and tired travelers refresh themselves in their cool shade.  They give us fruit to eat and firewood to burn.  We use trees to build houses and furniture's with.  If the paper on which your book is printed could tell its own story, it would perhaps tell you that once. it was a tree on some hill slope in a forest.  The furniture in your classroom is perhaps made out of trees that once grew in the forest of Assam or Kerala.  Trees thus supply us with many of the conveniences of life.

HOW TREES SUPPORT LIFE : 

HOW TREES SUPPORT LIFE Trees do much more than supply us with the conveniences we have mentioned.  They help to support man's life by supplying the atmosphere with oxygen which is essential to life.  The oxygen in the air is constantly being used up and turned into carbon dioxide when animals breathe and things burn, carbon dioxide is the food that plants “eat”.  The green leaves of trees (in fact of all green plants) absorb this carbon dioxide and with the help of sunlight break it down into carbon and oxygen.  The carbon is used 70 make starch, and the oxygen is released in to the air, so replacing the oxygen used up by animals.  But for this, animals would soon die for lack of oxygen.            Starch and other carbon compounds made in the green leaves of trees (and of other green plants too) serve as food for animals.  The tiny green cells of plants are wonderful laboratories, which produce all the starch in the world.  But for this service done by plants all animals would.  But for this service done by plants all animal would  sooner or larger die for lack of food; they must get all their food either directly from plants or indirectly by eating animals that have fed on plants.

INFLUENCE OF TREES ON CLIMATE : 

INFLUENCE OF TREES ON CLIMATE On a hot day it is often cooler under a tree than inside a building.  This is because the leaves of trees breathe out a lot of water vapour, and this helps to cool the air, more or less as a mudpat cools the water in it, in this way forests help to cool the atmosphere and the rain crowds passing through it, so causing rain.  Where new forests have been planted, rainfall it known to have increased.

INFLUENCE OF TREES ON SOIL : 

INFLUENCE OF TREES ON SOIL Trees help to protect the surface soil of the earth and to prevent floods.  Our earth has a covering of fine soil at the surface and under the soil lie rocks of various kinds.  Nature takes millions of years to form soil 2.5 cms thick.  But some times a single heavy shower washes off that much of the valuable surface soil on an open hill slope.  This does not happen in forests and other places where there are plenty of trees.  The trees stop the tree flow of water and their roots hold the soil together, and so the soil is protected from being washed off.  Moreover, forest soil has a way if quickly absorbing water, this helps to prevent sudden floods.

OTHER VALUES TREES : 

OTHER VALUES TREES There are many kinds of trees very useful to man.  There is the rubber tree growing in Kerala, Assam and Malaya from whose sap we get the rubber which we use for numerous purposes.  There are trees such as the eucalyptus and cinchona.  Which supply us with medicines.  There is the coconut tree, every part of which is useful.  In South America there is an interesting tree called the “Cow-Tree” whose sap's used in place of milk.

WHY SHOULD WE PLANT MEAN TREES : 

WHY SHOULD WE PLANT MEAN TREES In many parts of India there are not enough trees to supply firewood, and so people are forced to burn cow-dung, which ought to be saved for agricultural purposes.  The government wants large numbers of trees to be planted all over the country in order to make good the loss.  So, some years ago, the government started an annual festival called. Vanamahatsava or the forest festival.  This is an important festival in which we should all take part.  Threes are our country's wealth; we must consider it our sacred duty to protect them and to look after them well.

Slide 8: 

Trees are important, valuable and necessary to our very existence. It's not too hard to believe that, without trees we humans would not exist on this beautiful planet. In fact, some claim can be made that our mother's and father's ancestors climbed trees - another debate for another site. Still, trees are essential to life as we know it and are the ground troops on an environmental frontline. Our existing forest and the trees we plant work in tandem to make a better world.

10 Reasons Why Trees Are Valuable and Important

1. Trees Produce Oxygen : 

1. Trees Produce Oxygen Let's face it, we could not exist as we do if there were no trees. A mature leafy tree produces as much oxygen in a season as 10 people inhale in a year. What many people don't realize is the forest also acts as a giant filter that cleans the air we breath.

2. Trees Clean the Soil : 

2. Trees Clean the Soil The term phytoremediation is a fancy word for the absorption of dangerous chemicals and other pollutants that have entered the soil. Trees can either store harmful pollutants or actually change the pollutant into less harmful forms. Trees filter sewage and farm chemicals, reduce the effects of animal wastes, clean roadside spills and clean water runoff into streams.

3. Trees Control Noise Pollution : 

3. Trees Control Noise Pollution Trees muffle urban noise almost as effectively as stone walls. Trees, planted at strategic points in a neighborhood or around your house, can abate major noises from freeways and airports.

4. Trees Slow Storm Water Runoff : 

4. Trees Slow Storm Water Runoff Flash flooding can be dramatically reduced by a forest or by planting trees. One Colorado blue spruce, either planted or growing wild, can intercept more than 1000 gallons of water annually when fully grown. Underground water-holding aquifers are recharged with this slowing down of water runoff.

5. Trees Are Carbon Sinks : 

5. Trees Are Carbon Sinks To produce its food, a tree absorbs and locks away carbon dioxide in the wood, roots and leaves. Carbon dioxide is a global warming suspect. A forest is a carbon storage area or a "sink" that can lock up as much carbon as it produces. This locking-up process "stores" carbon as wood and not as an available "greenhouse" gas.

6. Trees Clean the Air : 

6. Trees Clean the Air Trees help cleanse the air by intercepting airborne particles, reducing heat, and absorbing such pollutants as carbon monoxide, sulfur dioxide, and nitrogen dioxide. Trees remove this air pollution by lowering air temperature, through respiration, and by retaining particulates.

7. Trees Shade and Cool : 

7. Trees Shade and Cool Shade resulting in cooling is what a tree is best known for. Shade from trees reduces the need for air conditioning in summer. In winter, trees break the force of winter winds, lowering heating costs. Studies have shown that parts of cities without cooling shade from trees can literally be "heat islands" with temperatures as much as 12 degrees Fahrenheit higher than surrounding areas.

8. Trees Act as Windbreaks : 

8. Trees Act as Windbreaks During windy and cold seasons, trees located on the windward side act as windbreaks. A windbreak can lower home heating bills up to 30% and have a significant effect on reducing snow drifts. A reduction in wind can also reduce the drying effect on soil and vegetation behind the windbreak and help keep precious topsoil in place.

9. Trees Fight Soil Erosion : 

9. Trees Fight Soil Erosion Erosion control has always started with tree and grass planting projects. Tree roots bind the soil and their leaves break the force of wind and rain on soil. Trees fight soil erosion, conserve rainwater and reduce water runoff and sediment deposit after storms.

10. Trees Increase Property Values : 

10. Trees Increase Property Values Real estate values increase when trees beautify a property or neighborhood. Trees can increase the property value of your home by 15% or more.
