Emission of Carbon

The London smog of 1952 killed an estimated 4000 people. According to an WHO report increasing carbon emission has caused many tropical diseases like malaria, dengue, and cholera to assume serious dimensions in Africa and Asia. Besides, it also worsens the problems of malnutrition and water-scarcity. It also adversely effects the rainfall pattern and causes droughts and families. It is reported that warming of the Earth’s surface by 3or 4 degrees may result in the elimination of 85 percent of the remaining wetlands and many species of water birds and turtles.
Records indicate that s a result of the emissions of these greenhouse gases, the year 1995 has been the warmest year so far since record-keeping began some 130 years ago. This increase in earth’s temperature has resulted in dwindling of food-grain production, shrinking of forest cover, extinction of many plant and animal species and acid rains. The average global temperature during 1995 was 15.39 C , breaking the previous record 15.38 C in 1990. This constant rise in temperature makes oceans release more energy into the atmosphere, leading to more violent storms and cyclones

Wonder of science

Today science has made possible to travel beyond the space. By its wonderful achievements science has so reduced the margin of impossibility that we are now apt to believe anything and everything to be possible. Science has, in the first place, invented railway trains, cycles and aero planes and many other means of transport, which undoubtedly add to human happiness. We can now go to distant places and countries in no time. All the different parts of the world have been brought closer to one another by these quick means of transport. Electricity which we use daily in lightning of our house is also a gift of science. It is through electricity that we enjoy the breeze of the fan in the summer season and the warmth of the heater in winter days. In addition to this, it also helps us in cooking, heating, cooling, ironing and in performing numerous other domestic jobs. In the departments of both medicine and surgery, science has added to the happiness of human beings. The discoveries of science have considerably helped humanity in fighting against fatal diseases like chicken pox, small pox, plague, rabies and even cancer. Medical science has opened the door for vast researches into the mysteries of drugs, and new medicines are being discovered almost every day to cure human suffering. Scientific discoveries and inventions have brought about great improvement in agriculture and have increased the production of land. Cinema, radio and television are some of the most popular means of recreation, which science has placed in the hands of man. Science has made man selfish, greedy and jealous. The greatest harm that science has done is the elimination of piece from our lives. All this certainly forces us to think and believe that science has come to us not as a boon but as a curse.
