Overview[ edit ] Between and Malthus published six editions of his famous treatise, updating each edition to incorporate new material, to address criticism, and to convey changes in his own perspectives on the subject. Malthus also constructed his case as a specific response to writings of William Godwin — and of the Marquis de Condorcet — He explained this phenomenon by arguing that population growth generally expanded in times and in regions of plenty until the size of the population relative to the primary resources caused distress:
Tuesday, May 1, essay on Environmental Protection In recent years mankind's consciousness has been aroused very strongly about the need for environmental protection and ecological preservation.
It is of utmost importance that the people should be aware not only of the problems involved but also of the role to be played in protecting the environment.
In addition it is also very essential to develop environment friendly technologies and renewable energy sources following the principle of conservation. While developing technologies for the benefit of man, it is also essential to study simultaneously their impact on the environment so that cyclic processes, which the nature has devised for conservation of resources is not affected.
Air, water and land are the basic amenities of life. But over population and rapid industrialization have created a state of decadence in the environment. Man has continuously tampered with the nature. As a result a threat to his life has been increased, due to the lack of healthy air and potable water and the imbalance established in the biosphere.
Earth is, perhaps, the only planet endowed with an environment and we all share it.
One dy we would pass it on to our future generation as their legacy. But if they will inherit such a polluted environment, life will be misery for them.
Men has improved the technologies and other means necessary for higher production of wealth and exploited nature for his benefits, but without any foresight as to what to implications of his actions would be.
Indiscriminate industrialization has resulted in urban migration and slum development, which in turn resulted in degradation of environment.
Before the advent of modern civilization man lived and flourished amidst the nice balance of multiple biological process. As the most intelligent being on earth man has constantly tampered with the nature making use of his inventive genius and disturbed the ecological balance.
Thus, air, water and soil, all have got polluted and posing threat to the substance of mankind. The result in numerous health problems. Air pollution is due to the direct implication of industrialization.
The chimneys of industries emit smoke and vehicles have fumes, which directly contribute to air pollution. Any gaseous material not considered a a normal constituent of air or excess of sulphur dioxide, carbon monoxide, nitrogen dioxide, dust etc. Air pollution also occurs when forests catch fire, rubber plants are gutted or plastics are burnt along with the household garbage.
This danger of pollution has been aggravated today due to atomic explosions in some advanced countries. Some hovering over the cities in they early morning is also the result of air pollution.
The depletion of ozone layer, which is very essential for life to protect from dangerous ultraviolet light, is also due to air pollution and it may result in skin diseases. The emission of greenhouse GHGs like carbon dioxide in increased concentration has led to climate changes.
Although it does not have toxic effect, it is largely responsible for green house effect and thus for global warming. Most of the air pollutants directly affect the respiratory and cardiovascular systems.
Nitrogen dioxide and ozone also effect the respiratory system, irritate the eyes, nose and throat and in addition ozone can cause headaches. Carbon monoxide is able to displace oxygen in the blood which in turn can result in cardiovascular and neurological effects.
Lead affects bone narrow, impairs liver and kidney function, causes neurological damage and limits metal development in children. Although earth is surrounded by water in its three fourth area yet drinking water has a scarcity. All main source of portable water like rivers, lakes, ponds, even wells have been polluted by various dangerous chemical and biological wastes.Misc thoughts, memories, proto-essays, musings, etc.
And on that dread day, the Ineffable One will summon the artificers and makers of graven images, and He will command them to give life to their creations, and failing, they and their creations will be dedicated to the flames.
Grab the weapons (Booklist) As such, there is no single “comprehensive” book for the CAPF exam. All I see is some Jholachhaap publishers’ copypasting chapters from other books meant for Bank PO + add some GK material + give last 3 years’ question papers = market it as SSC/CPF/GPSC guidebook.
