Plant Trees, because...

...it's roots can prevent soil erosion...


Soil erosion is actually a natural process, but it can be accelerated with human activities. Its natural causes are wind and water by downward movement caused mainly by gravity while human activities like excessive logging and road building can do as much damage but at a faster rate. One of the main causes of erosive soil loss in the year 2006 is the result of slash and burn treatment of tropical forest. When the total ground surface is stripped of vegetation and then seared of all living organisms, the upper soils are vulnerable to both wind and water erosion. In a number of regions of the earth, entire sectors of a country have been rendered unproductive. Shifting cultivation is a farming system which sometimes incorporates the slash and burn method in some regions of the world.
One effective way to prevent soil erosion is by planting trees.

*Trees cover land areas and so the soil beneath it is protected from being washed away.
*Trees break rainfall and strong gusts of winds therefore preventing much damage and decreases the soils vulnerabity to erode.





...it can absorb tons of water...


The main force which draws water from the soil and through the plant is
caused by a process called transpiration. Water evaporates from the leaves
and causes a kind of 'suction ' which pulls water up the stem. The water
travels up the vessels in the vascular bundles and this flow of water is
called the transpiration stream. The water vapour passes by diffusion
through the air spaces in the mesophyll and out of the stomata. It is this
loss of water vapour from the leaves which is called transpiration. The cell
walls which are losing water in this way replace it by drawing water from
the nearest vein. Most of this water travels along the cell walls without
actually going inside the cells. Thousands of leaf cells are evaporating
water like this and drawing water to replace it from the xylem vessels in
the veins. As a result , water is pulled through the xylem vessels and up
the stem from the roots. This transpiration pull is strong enough to draw up
water 50 metres or more in trees.





...it can be a very good shade...



Shade trees are effective in reducing the energy used in cooling homes. Some of the most popular shade trees are oaks, maples, ashes, lindens, and elms.

Things to look for when choosing a shade tree include deciduousness, coverage, longevity, and the ability of the roots to damage foundations.

A common use of shade trees is for leisurely sitting and relaxation. People of all ages partake of this, especially retired persons.

Shade trees, as any vegetation, can add to privacy in a garden by obstructing the view. However, in cool climates, an abundance of shade trees may lead to an overly dark and moist environment in a building and the garden surrounding it.





...it takes in Carbon Dioxide and gives off Oxygen...


Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars). Photosynthesis powers almost all trophic chains and food webs on the Earth.

The net process of photosynthesis is described by the following equation:

6CO2 + 6H2O + Light Energy = C6H12O6 + 6O2

This equation simply means that carbon dioxide from the air and water combine in the presence of sunlight to form sugars; oxygen is released as a by-product of this reaction.





...and as an added bonus, you can enjoy it's fruits...


Fruits provide lots of vitamins and minerals needed in our daily healthy living. They can be consumed as it is, turned into juice, dried, preserved, and a lot more. So why not order live trees today! or you can give the gift of trees.
