The main trunks of large trees like the mango and the banyan bear many branches, which further divide into smaller branches. Leaves grow on these branches. Branching causes the tree to spread out wide on all sides. Trees are Nature's wonders and a great gift to mankind as well as to all those who depend on them. While some dependants stay on the trees, others come to them to rest or to feed. Still others use them to raise their offspring. Humans have used almost any and every tree to their benefit. It is very sad that the same humans are destroying trees all over the world in the name of "development". This can be to create factories, new townships, wider roads, railways, entertainment centres and so on. They do not realise that they are making a big mistake. 2.0 Usefulness of trees: 2.1 How trees are useful: Trees are useful to us in many ways. 1. Food: Trees give us food such as fruits. These provide us with excellent nourishment. 2. Wood: The wood from some trees such as teak, walnut, rosewood and oak is used to make furniture. Wood from other trees is used as fuel for cooking and for warming houses. 3. Paper: Paper is made from wood. 4. Medicines: Many trees are the source of useful modern medicines. 5. Shelter: The canopy of leaves and branches gives us shelter. 6. Climate: Trees provide cool shade. Many trees, for example, in a forest, can make the climate pleasant and the air clean. 7. Rain: Forested areas get better rainfall compared to areas with no tree cover. 8. Oxygen: When trees respire, they release oxygen that all animals need for their survival. 2.2 Examples of usefulness of trees: Have you eaten an apple? A mango? Then you will know what I mean when I say that trees provide food. Other fruits like jackfruit, coconut and figs also grow on trees. Most of the furniture in any house is made from wood. In mountainous regions, even the walls are made from logs of trees. In cold areas, where people need to heat their homes, wood from trees is used for heating. Many medicines are derived from trees. These include medicines for fever, malaria and heart-diseases. By absorbing the extra carbon dioxide and releasing oxygen, trees help make the environment clean and more suitable to live in. Forested areas are pleasantly cool, get better rainfall and have cleaner air. Many trees are grown especially for their products, such as the rubber tree, which gives us rubber that is so useful to us. Nowadays, a lot of rubber is made synthetically in factories. Forests: 3.1 What are forests? Forests are dense collections of trees, plants, animals and birds within a small area of the earth. The Amazon rain forest is the biggest forest in the world. Many of the forested areas are protected by the national governments and converted into parks and wild life sanctuaries. 3.2 Environment and forests: Large forests are fine-tuned ecosystems which can influence the climate and environment not only where they are but also all over the world. For example, the forests all over the world are shrinking, thanks to the irresponsible felling of trees for "development". This is thought to be one of the most important reasons for global warming. There are several ways forests can be misused to cause harm to the ecosystem: this includes strip logging, indiscriminate setting of fires to clear forest land for development and using deforested areas for rather low-yield agriculture. There is a lobby out there of governments, politicians, foresters, social scientists and environmentalists who vote for constructive development for the common good of the society. It seems prudent, for example, to remove a few trees that come in the way of construction of a 500-mile highway. At the same time, it is irresponsible to hack down a 70-year old teak tree just to get firewood for one's house. I fully agree with this kind of responsible forest management. 3.3 Greenhouse effect and global warming: As you know, living things are able to survive on earth only because the earth's climate is suitably warm. This is possible because the earth's atmosphere traps the sun's heat on the surface of the planet. If this trapping had not occurred over the past billions of years, plants and animals would not have evolved, as the earth would have remained a frozen planet. This is known as the Greenhouse Effect. Due to the increase in carbon dioxide and other greenhouse gases in the environment, the earth is gradually becoming warmer and warmer. This warming can have huge and terrible effects on all of us: it can lead to unseasonal rains, flash floods, prolonged droughts and extremes of temperature in the summer (more hot) and winter (more cold). The ice-caps on the tops of mountains and the ice continents can melt, leading to even more problems for humans as well as all living things on earth. Now imagine a world with millions of more trees than what we have at present. In such a world, most of the extra carbon dioxide would get absorbed by the trees, which need this gas for making food for the entire planet. At the same time, globally, more trees would mean better rains, cooler climates, and decreased use of air-conditioners and refrigerators. This would reduce the other greenhouse gases as well, leading to reversal of global warming. What a wonderful thing to happen! 3.4 Soil conservation: Trees help to prevent destruction of the fertility of soil as well as stop soil erosion, particularly on slopes and mountains. By protecting soil fertility, they allow a better yield of crops and help feed more mouths all over the world. They thereby help to reduce malnutrition, poverty and hunger. 4.0 Benefits of growing more trees: Most people do not realise the benefits they can get by growing trees. See the paragraph on usefulness of trees above. Imagine a farmer who needs supplemental income from the farm. Why, he can grow some commercially useful trees such as fruit-bearing ones or trees with hard wood such as teak or walnut. Professional farming is known as "silviculture". Imagine a corporate HQ that has no trees. This would definitely annoy a discerning visitor Just think how many weary travellers would be benefitted by the stategic placement of shelters covered by large canopies of trees? Just think about it and decide yourself. 5.0 Conclusion: Trees are immensely useful to all of us. They give us so much, taking almost nothing in return! They help us to remain calm and cool, provide us with a charming surrounding and share their wealth with us so selflessly. Better management of forests would allow governments to responsibly cut down trees and develop those areas for the welfare of society. However, we must condemn irresponsible, unsupervised hacking of trees anywhere on the planet. At the same time, we must grow more and more trees. End |
