importance of trees and urgent need of planting more trees
Answers
Answer:
The importance of planting trees has been emphasized time and again. This is because of the numerous benefits they offer. One of the main benefits of planting trees is that they provide us with the life giving oxygen. Without the presence of oxygen the survival of living beings is not possible. Planting trees is also essential because they have the power to absorb the harmful gases. The growing pollution caused due to carbon mono-oxide, sulphur dioxide and other harmful gases and smoke emitted by vehicles and industries is controlled and purified to a large extent because of the presence of trees.
Trees also provide shelter to birds and animals. On a hot summer day, they even provide respite from the scorching sun to the travellers. Trees make our planet worth living. But even though trees offer numerous benefits and we cannot imagine our lives without them, we are cutting them at a rapid pace to fulfil various needs.
Wood is used for making various products of necessity as well as luxury. This is the reason why several trees are being cut each day. The growing population is another reason why numerous trees are being cut speedily. Forests are being turned into industrial areas and residential places.
It is the time government must put a restriction on the cutting of trees and encourage people to plant more of them.

Answer:
Importance of trees:
The various ways trees benefit us are-- Plants and trees provide us with food, fiber, shelter, medicines like aspirin tablets, shades, and firewood. Sponges, chewing gum, henna dye, rubber, etc. The basic food for all organisms is produced by green plants. We should be seriously more involved in tree plantation. Consider the following points for a better understanding.
1. Trees stabilize the soil. In the absence of trees and forests the fertile top soil is washed away by rainwater making cultivation impossible.
2. Greenery is not mere foliage. Trees prevent desertification.
3. Trees retain water in the soil. Without forests the entire rainwater flows into the sea. The water is then not available as ground water. Thus we experience flash floods followed by severe droughts and cultivation becomes impossible.
4. If deforestation continues unchecked, there will be violent riots for water due to scarcity caused by droughts and pollution of rivers and lakes.
5. Trees are water bearer. Without trees rainfall will decrease and cultivation will become rather a matter of luck. There will be worldwide food scarcity causing famines.
6. Trees are oxygen cylinders. Trees absorb the harmful Carbon dioxide and release Oxygen. Deforestation contributes to the decrease in oxygen level and increase Carbon dioxide in the atmosphere. Increased Carbon dioxide level results in lungs diseases, cancer and lower life expectancy.
7. Trees are air conditioners. Trees keep the temperature temperate.
8. Trees and forests are habitats of wild birds and animals.
9. Forests are store houses of many medicinal plants.
10. Trees also reduce air and noise pollution.
11. Trees add beauty to the landscape.
Trees do much for us. But human beings are felling them in large scale for the timber industries for financial gain. Population growth is leading to the decreased forest cover of the earth. The consequences will be catastrophic. Let us all join hands to plant more trees in a war footing, our quality of life and survival depends on it.
