People are very careless about their attitudes towards the environment. Very few have developed habits that are environment - friendly. Here are some ways in which we can help save the environment and keep it clean. We should make it a habit to use bins to throw in waste, wherever we are. We should find ways of recycling paper. We should definitely avoid plastics at all costs. Also we should avoid packaged and canned, food, as the containers are just thrown away and become part of the litter that accumulates everywhere. We may opt for alternative mode of transport like bicycles. Most importantly. We must save the existing trees and plants more trees.
FRIENDS OF TREES
FRIENDS OF TREESinvite one and allto a massiveTREE PLANTATION DRIVEFriends, our town is in jeopardy.Have you noticed that thenumber of birds have become scarcein our localities ?Have you noticed how high the temperaturesare in summer ?Tree plantation is a dire need, indeed,Everyone's cooperation is earnestly solicited.
Trees - Nature's gift to man : Trees are Mother Nature's precious gift to man. Directly or indirectly, they provide him with all his basic necessities, viz,,, air,,, water, food,, clothing and shelter. They also provide important raw material for our industries. Industries provide employment to people. The wood for furniture, housing and ships comes from trees. Woods is also used for fuel and for making charcoal. Wood pulp is used to make paper and artificial yarn. Trees also give us products such as spices, rubber, turpentine, eucalyptus oil, gum and medicinal products. No wonder forests are knows as ' green gold'. Trees provide shade to tired travelers and animals and shelter to innumerable birds and insects. Trees check strong currents of wind and water and thereby prevent soil erosion. Trees keep the air clean. Forests retain humidity and attract rains. It is for this reason that trees are known as rain catchers. They absorb harmful carbon dioxide from the air and fill the atmosphere with precocious life-sustaining oxygen. In this way they reduce air pollution. Therefore, trees are called the ' lungs of nature'. We thus owe our very existence to trees.
{ The goldmohur tree is of medium size. It has a modest height. It has compound leaves that have a feathery appearance. They are bright green in colour. Its flowers are bright orange, red and yellow. However, it bears no fruits, It has leguminous roots that have nitrogen-fixing properties. The banyan tree, on the other hand, is large and tall. Its leaves too are large. They are glossy green in colour and elliptical in shape. The banyan tree has no flowers, but it does bear the fig fruit. The banyan tree is specially noticeable for its aerial roots. }
Profile of the Coconut Tree: The Sanskrit name of the coconut is Narikela, while in Hindi, it is knows as the Nariyal. Its scientific name is Cocos nucifera and it belongs to the palm family known as 'Palmae'. This tree is of Indo-Pacific origin, either around Malaysia or the Indian Ocean. In plantations, this tree can grow from 15 to 30 meters in height. It usually grows well in tropical and sub-tropical coastal regions. It is especially found near sea beaches and along coastlines. In India, this tree is known as the 'kalpavriksha' or the 'tree of heaven' because of its many uses.
Prevention is better than cure :- We sometimes handle a knife carelessly, cut our fingers, allow the cut to go septic and, when the pain is unbearable, consult a doctor, The doctor prescribes a prolonged and costly treatment. Wouldn't it have been better for us to have taken due precaution while using the knife ? In fact, we can always protect ourselves against common ailments and diseases by resorting to proper precautionary, preventive measures. Very often, we are careless and do things thoughtlessly. We ignore signs that indicate the possibility of trouble. Finally when the trouble occurs, we regret our neglect, but by then it is too late.
The proverb ' Prevention is better than cure' advises us to take necessary steps to stop something unpleasant from happening. This proverb has application in the proper maintenance of machines, buildings, roads or bridges, health care, in the averting of natural calamities , in the prevention of epidemic outbreaks and even at the political and nations level. The proverb stresses the need for foresight and precaution in dealing with every situation in our lives in order to avoid facing misery and searching for expensive remedies later on.
The tree is not an immutable biological category but rather a human concept based on visual criteria. Perhaps a general definition would describe a tree as a perennial woody plant that develops along a single main trunk to a height of at least 4.5 meters (15 feet ) at maturity. This may be contrasted with a shrub, which might be loosely defined as a woody plant with multiple stems that is, in most cases, less than 3 meters (about 10 feet ) tall. However, a species fitting the description of either in one area of the world might not necessarily do so in other regions, since a variety of stresses shape the habit of the mature plant. Thus, a given woody species may be a tree in one set of habitats within its range and shrub elsewhere For example, the spruce and fir may thrive in the tree form at the base of a mountain but assume a shrub form near the mountaintop, the variation due principally to stresses exerted by such environmental conditions as altitude, temperature, and oxygen tension.
As seen in the section above, trees are found among many plant families that also include shrubs and herbs, so that the concept of tree is not a phylogenetic one. Further, there is no clear consensus as to whether the tree form is the advanced or primitive condition, Some paleobotanists suggest that tress are the most primitive members within these plant families. However, tree forms are found in all the vascular plants, from the club mosses and ferns to the gymnosperms and angiosperms. It is furthermore true. that, among the flowering plants, tree are found - not only among the most primitive members (order Magnolias ) but also among the more specialized, or advanced, members, such as the roses ( order Rosales ).
Consequently, form both taxonomic and a phylogenetic perspective, the tree is an artificial category. On an ecological basis, however, the tree can be recognized as a natural construct, as it represents an adaptive strategy by many different taxa to exploit and dominate the habitat above the ground. In the early stages of the development of terrestrial life, land plants were rootless and leafless. Since they had their origins in aqueous environments, they did not require the specialized conducting and supporting tissues afforded by roots and stems, nor did they require localized regions of carbohydrate synthesis, since each cell was involved regions of carbohydrate synthesis, since each cell was involved in metabolism, water and nutrient absorption, and respiration. Habitats farther form the water as well as aerial habitats represented available uninhabited environments.
One key to exploiting terrestrial habitats is increasing complexity of the plant's form to allow specialization of function This requires physiological and morphological complexity as well as biological optimization. If all the tissues of massive tree trunks were alive, for example, the physiological cost of maintaining these structures in the living state would be enormous and probably unattainable. An elegant solution came in the form of tremendous structural adaptations : new tissues and organs permitted localization of the functions of the plant body. The evolution of discrete plant body parts with separate functions allowed plants to move onto the land and undergo an incredible adaptive radiation. Leaved evolved as specialized photosynthetic organs. Stems provided mechanical strength as well as a conductive capacity to transport water and nutrients from the roots to the leaves. Roots provided anchorage and absorption of sufficient water and nutrients to support the reminder of the plant.
Glossary : Prevention is better than cure - It is better to stop something bad from happening than to deal with it after the damage has been done. Precaution - an action which is taken in advance to prevent something unpleasant or dangerous from happening. Septic - infected by bacteria. ailments - diseases. Foresight - the ability to judge correctly what is going to happen in the future and to plan your actions based on this knowledge.
A tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth. plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms. tree ferns, bananas, and bamboos, are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long- lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world.
A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically contains woody tissue for strength, and vascular tissue to carry materials from one part of the tree to another. For most trees it is surrounded by a layer of bark which serves as a protective barrier. Below the ground, the roots branch and spread out widely ; they serve to anchor the tree and extract moisture and nutrients from the soil. Above ground, the branches divide into smaller branches and shoots. The shoots typically bear leaves, which capture light energy and convert it into sugars by photosynthesis, providing the food for the tree's growth and development.
Trees usually reproduce using seeds. Flowers and fruit may be present, but some trees, such as conifers, instead have pollen cones and seed cones. Palms, bananas, and bamboos also produce seeds, but tree ferns produce spores instead. Trees play a significant role in reducing erosion and moderating the climate. They remove carbon dioxide from the atmosphere and store large quantities of carbon in their tissues. Trees and forests provide a habitat for many species of animals and plants. Tropical rainforests are among the most biodiverse habitats in the world. Trees provide shade and shelter, timber for construction, fuel for cooking and heating, and fruit for food as well as having many other uses. In parts of the world, forests are shrinking as trees are cleared to increase the amount of land available for agriculture. Because of their longevity and usefulness, trees have always been revered, with sacred groves in various cultures, and they play a role in many of the world's mythologies.
