The Greenhouse Effect


The Greenhouse Effect


The 21st century is a century of progress but also a century of huge environment pollution. The greenhouse effect is a serious testimony of environmental disaster. The gradual warming of the temperature of the air surrounding the mother earth as a result of heat being trapped by environment pollution is termed as ‘Greenhouse Effect’. Excessive use of carbon-di-oxide is worsening the situation and thus heat cannot pass through the atmosphere. As a result, temperature is increasing rapidly. Most climatologists believe the greenhouse effect is the likely cause of this global warming. The cause of greenhouse effect is the destruction of tropical rain forests, the rapid urbanization and industrialization, the use of CFC’s and detergents etc. The oceans, the rivers, the open fields and the atmosphere are being polluted by man. The burning of fossil fuels and the widespread use of chemicals has threatened our existence. The result of the greenhouse effect is terrifying. Temperatures may rise by as much as 4°C by the next 50 years which could flood the coastal areas of Bangladesh and many other low-lying countries. As a result, it can seriously destroy our wild life and wilderness, rise in sea levels, and sharp fall in the crop production. The bottom line is that the greenhouse effect is a serious environmental disaster and we must stop deforestation and massive emission of carbon-di-oxide to avoid this damage.

Improve Grade -- Drink Water !!!


Drink water before exam, improve your grades. ||

Drinking a glass of water could help you do better in exams, researchers have suggested.

A new study found that students who took a drink, such as water before taking an exam did up to 10% better than those who did not the difference between a grade. It is unclear why a drink should help, but one theory suggests that information flows more freely between brain cells when they are well hydrated. Drinking water may also calm nerves, while those who became thirsty during the test could be more easily distracted, the Daily Mail reported. The study, which looked at hundreds of university students, compared whether they took a drink into the exam with their marks. The students' overall academic ability was then factored in. Those who arrived with drinks did around 5% better on average. But the improvement was even more marked among those just starting out at university, whose results improved by as much as 10%.
