...Acid Rain – Save the Environment Acid rain, or any other form of precipitation with high nitric and sulfuric acid levels is when the precipitation has a lower pH than natural unpolluted rainwater, 5.5 (National Geographic). Acid rain is the result of combustion of fossil fuels which releases acid chemicals into the air (Wysession, Michael). It is a problem in the world since it effects natural and man-made environments as well as other factors in negative ways. The unpolluted water that rains down on us is always slightly acidic with a pH of around 5.6. This is because the rainwater from the clouds react with the CO2 (Carbon Dioxide) that is in the air. It is in the air due to that we convert the oxygen that we inhale into CO2 inside of our bodies, which we later exhale. This results in a solution called Carbonic Acid. (Wysession, Michael) Water | + | Carbon Dioxide | | Carbonic Acid | H20 | + | CO2 | | H2CO3 | Rain counts as acid rain when it goes below the unpolluted rain pH, 5.6. The acidity of acid rain can be as low as 2.7 on the pH scale depending on the ratio of chemical acids and unpolluted rainwater. However, the usual pH of acid rain is around 4.0 which is more than 10 times more acidic than unpolluted rainwater. (Wysession, Michael) Acid rain can be caused by natural sources such as volcanoes. However, the main cause of acid rain is when the acidic chemicals sulfur dioxide (SO2) and nitrogen oxides (NOX) are released into the air by the combustion of...

...Larkin has been regarded as one of the most pessimistic poets. Larkin surely takes a very dark view of human life. The main emphasis in his poems is on failure and frustration in human life. And then there is his preoccupation with death. In a number of poems he emphasizes the sombre and grim aspects of human life and in many poems he speaks of the cert of death. We are all aware of the facts of failure and frustration in human life and we are all aware of the faith of death. But what makes Larkin a pessimist, and a confirmed pessimist at that, is his repeated emphasis, and over-emphasis, on these aspects of human life. On explanation of his repeated reminders to us of the certain of death, he has been regarded as “a graveyard poet”; and the general and brooding atmosphere of melancholy and despondency in his poems justifies the label “pessimist” for him. A number of poems come to our minds in this connection. The poem Ambulances paints a gloomy picture of human life because of the fact that every street is visited by an ambulance at one time or the other. An ambulance is a symbol of disease and death. Dockery and Son contains the following pessimistic line: “Life is first boredom, then fear”. And this poem concludes with the pessimistic view that there is old age, and that the end of old age is death. Aubade is a poem in which Larkin’s fear of death reaches its climax. Larkin himself described it his “in-a-funk-about-death poem.” The Positive Features of His Pessimistic...
