What are Trees ?

A tree is a plant which has a trunk protected by bark. Most trees can grow to a height of many different shapes and sizes. Some species of trees, which we call ‘evergreen’ are do not lose their leaves. Instead they change their foliage a little at a time in rotation. ’Deciduous’ trees lose all their leaves once each year, at the start of the coldest or driest season.

The trunks of trees are protected by bark, a dense layer of dead cells. The bark protects the tree against insects, parasites and sharp changes in temperature.

Each tree bark has a distinctive appearance, just like a person’s fingerprint.

Why we need trees?

Well the obvious answer for the above question will be to live. As everyone knows we cannot survive without oxygen, and trees are the main source of oxygen on Earth. So in order to live we are dependent on the trees, but our friends Trees give us much more other things than just oxygen.

Trees provide nutritious Food

People from all over the world gather nutritional products from trees including fruits, nuts, seeds, leaves, bark and even sap. An apple a day keeps.... we all knows the rest. An apple tree yield up to 15-20 bushels of fruit per year. Apples are often eaten raw. Today, products such as mangoes, oranges, pistachios and brazil nuts are routinely eaten all over the world.

Trees save and clean water

Shade provided by the trees slows water evaporation. Trees reduce runoff by breaking rainfall, therefore allowing the water to flow down the trunk and into the earth below the tree. This prevents storm water from carrying pollutants to the ocean. When mulched, trees act like a sponge that filters this water naturally and uses it to recharge groundwater supplies.

Trees clean the air

Trees absorb odors and pollutant gases and filter particulates out of the air by trapping them on their leaves and bark.

Trees provide a habitat for wildlife

Trees provide shelter and food for a variety of birds and small animals, such as squirrels and beavers.Forest are home of many animals.

Trees combat climate change

Excess carbon dioxide (CO2) caused by many factors is a building up in our atmosphere and contributing to climate change. Trees absorb CO2, removing and storing the carbon while releasing the oxygen back into the air.

Trees provide health

Studies have shown that patients with views of trees out their windows heal faster and with less complications. Exposure to trees and nature aids concentration by reducing mental fatigue.
