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
