Global warming Sir, Pollution is associated with our daily life. Every day we contribute, knowingly or unknowingly, to one type of pollution or the other. Among various types of pollution, air pollution has remained a cause of serious concern since long. The burning of fossil, fuel, emission of harmful gases from factories deforestation and urbanisation has lead to increase in air pollution. Every year about 23 billion tonnes of carbondioxide are emitted over the world. All these factors have resulted in the increase in temperature of atmosphere immediately surrounding the earth. This heating up of the atmosphere is called Green House Effect which leads to the Global Warming. Global warming is altering the habits, migration and breeding of animals. This could eventually affect humans. Already, Coast Rican forest birds are migrating to cooler areas. And it is estimated that sea birds of the Pacific Coast might vanish in ten years. These changes will have a very serious impact on human welfare as there are million of people around the world who depend on wild life for food (directly or indirectly), clean water and medicine. A large amount of obnoxious gas carbon dioxide is being emitted world wide. The emission is mainly due to the burning of fossil fuels and from cement factories. The amount of emission of carbonioxide is 5301 tonnes only in the United States of America (USA). If this trend of harmful gases emission remains increasing as such, it is estimated that the global temperature will rise by 4.5 degree celcius by the year 2030. This will result in melting of Polar ice caps and in turn flooding of low lying areas. A study by the World Wide Fund for Nature (WWF) had documented how several species of birds, plants and other wildlife were adopting to gradual warming of the Earth's atmosphere. Environmentalists have not yet noted the impact of global warming on human food supplies. The first sign of the future trouble could be in something like the decline in the Population of ducks which are hunted in US. This in itself should be an indication of troubled times to come. It is said that the only option to protect animals is to adopt strict restrictions on the emission of Green House gases which are responsible for the gradual increase in the temperature of the planet. It is suggested to introduce a certain percentage of ethanol methanol to gasoline so as to reduce the emission of carbonmonoxide and the hydrocarbons. It is also suggested to set up a high level body to look into the issues concerning the vehicular and industrial emission. The solution to this global pollution lies in the effective functioning of the Pollution Control Boards. Yours etc.. |
