Essay on Indian Beggar

The Indian beggar is very persistent. Wherever we go he is sure to follow us.
We stop to talk to a friend for a minute and he is there. We go to a shop to buy something and he is there too. There is no escape from him. There are two classes of beggars.
First there are those who are strong and able bodied men. They can work as well as anyone of us. But they do not work for their living because they find it easier to live on the charity of others. No alms should be given to such beggars. Then there are those who are old and weak and even disabled.
Such beggars should be pitied and helped. They should be provided with food and clothing. The Indian beggar is an object of pity. He has no means of earning his livelihood. He lives by begging. He goes about quiet naked except for a small lion-cloth.
His body is covered with dirt and ashes. His hair is long and dirty. He never washes his face and hands because he thinks that the dirtier he looks, the more the people will pity him. He carries a begging bowl made of clay. He goes from shop to shop begging for food or money.
There are very few people who receive him well. When he goes to them for alms. They sometimes abuse him, even beat him and turn him out of doors. It is only women who show him some mercy. They think that alms given to poor will bring them blessings in the next life.
Some beggars are really lazy and wicked fellows. They commit thefts at night. Such beggars should be given nothing. They should be caught and punished. They should be made to work for their living like honest people.

Essay on Effects of Cell Phones on Our Health

Carrying expensive cell phones in our pocket for pleasure and purposely exposing it in front of our buddy does wonders to our reputation and personality. Everyone adores having a cell phone in this era. Particularly, we youngsters set upon moving with cell phones to schools and colleges.
It’s good to be a part of assortments of technological world. But the growing technology is likely to threaten the life of people by giving out detrimental radiations. Yes, the mobile phones which help us to become the big cheese among our mates essentially turn out to be like an arm and a leg when we start getting on various devastating syndromes in our upcoming days due to its hectic use. Today every one owns a cell phone which is rather prominent but its frequent use is not acknowledgeable as frequently counting on such devices could escort to death too. Cell phones emit radiations which is not affordable by our subtle body. The radiations are likely to debacle off our body cells and damage our DNA in laboratory condition; more powerful 3G phones can harm brain functions.
Mobile phones use electromagnetic radiations in microwave range which may be harmful to human health. Other wireless phones too emit the harmful rays which straightforwardly break into our head and subsequently, creates aggravated conditions like brain tumor and of course cancer. On the other hand youngsters solely paint the town red and consequently get engrossed from studies by its addicting features.
In spite of having at least some knowledge on drawbacks of cell phones people still don’t lessen its use. But instead a single person keeps innumerous mobile phones in use whether it is necessary or not. The habit of using mobile phones recurrently would harm us and others as well. We should not draw on mobile phones at critical public places where it is strictly prohibited like that of hospital especially near Operation Theater as it may also result in death of the patient due to the disruption created by radiated harmful rays emitted by cell phones in the happening operation.
The dazzling snags are indefinite in numbers but solutions are too hard to adopt as it would be certainly to lessen the use of legendary cell phones and there are other solutions too like employing only telephones at home, getting the access of internet just for online talking purpose with friends and relatives. But be careful about that systems too emanate radiation but not as harmful as mobile phones.
Hence we ought to adopt it as it would be beneficial in being fit as a fiddle and lasting for long time to even enjoy the beautiful life with the upcoming generation.

Essay on the Distribution of Toxic Material in the Environment

Toxic material released in the environment may remain at the point of their discharge or' be transported to other place. The distance up to which they are transported depends mainly on the mobility of the agent carrying them. Moving waters and air currents are effective media for transfer and transport of toxic substances. The mobility of a toxic material is however, not confined to their dispersion within a single medium.
Materials released into water may get distributed in soil and air as well. Toxic material released into atmosphere may contaminate soil as well as water. Wastes discarded on the soil may contaminate the water which seeps through it or the air may get contaminated when it carries the vapours or small particles of the toxic material.
Pollutants can enter a biological system from any of the three media, such as water, soil on which carry them. In lower plants and animals, plasma membrane is the main barrier between outside environment and the biological system inside the cell.
In higher plants and animals we possess much better protective devices such as coating of wax, cuticles, multilayered epidermis pollutants have to take other routes. These routes may be through the roots, root-hairs, rhizoid stomata etc. in plants and through nasal mucosa and mucosal lining of mouth, respiratory track and gastro-intestinal track in animals. In many cases, the epidermis is pervious to certain types of pollutants.
Nature has provided higher animals including man with an efficient device which helps them to guard against pollutants which regularly enter through intestinal track. Materials absorbed from intestines are routed through hepatic portal system to the liver wherein harmful constituents are reacted upon by liver's enzymatic machinery.
A number of harmful materials absorbed intestines are degraded or converted to harmless state before reaching the blood circulation However, this is not so in the case of pollutants entering the system through respiratory track. The air in alveoli of lungs is in direct contact with blood in capillaries across a thin membrane. The material absorbed enters straight into the blood circulation. This becomes more significant in to light of the fact that we breathe in by weight about 16 times more air than total foodstuff and water consumed orally.
The plasma membrane through which all substances entering a cell must pass is lipoprotein membrane being made up of a thin layer of lipid or lipid like substance covered on both sides by a layer of proteins. The basic structure of plasma membrane is strikingly uniform throughout the living world.
The rate of entry of the toxic material into a biological system is influenced by the size of its molecules, its concentration in the medium, the nature and solubility of the substance in water as well as in lipids and fats. Substances soluble in lipoid material (lipophilic ones) are carried across the plasma membrane simply by dissolution and diffusion through the lipid layer. Lipoid insoluble but water soluble toxic material (hydrophilic ones) may require an active transport mechanism. Smaller molecules such as those of water simply pass through pores in membrane.
Inside a biological system the toxic material may be either stored or is reacted upon by the enzyme system and excreted. The phenomenon of accumulation of toxic agent inside cells and tissues of living organisms at concentrations above those of immediate environment is known is Bio-accumulation.
The toxic material soluble in lipoid substances or capable of forming complex with macromolecules within the cell may be stored for long duration of time as they are excreted very slowly. By virtue of complex formation and dissolution is lipoid materials which are storage products of cellular metabolism, these substances stay away from the enzymatic reaction which act on then the toxic material once inside a living organism may be concentrated several thousand times the process of Bio-magnification which causes enhancement in the concentration of toxic along the food chain.
Toxic agents who enter a living organism at the level of primary producers get concentrated many thousand times as they move up along the food chain to higher trophic levels. Thus, it is not only air, water or soil which may carry the toxic material of persistant nature.
The toxic agent may accumulate and be biomagnified through the food chain thus contaminating the entire biotic component of the locality. If the food we eat comes from organisms growing in contaminated environment, plants or animals, there is every possibility that it carries small amounts of toxic substance - the chances of getting higher concentration of toxic agent being higher and higher at higher trophic levels.
