Read the given paragraphs carefully and answer the questions which follow each of these.We are living in the midst of a great chemical experiment, and some serious consequences are becoming apparent to scientists. More than two billion pounds of chemicals are spewed into the air each year which are brewing a disastrous stew. The greatest consequences of the atmosphere crisis may be global warming and the ozone depletion. The Earth appears to be warming due to the greenhouse effect. Scientists estimate that average temperature could climb about 2 degree Celsius in 20 years. Global warming is the predicted result of the greenhouse effect, created by the greenhouse gases, such as carbon dioxide and methane, in the atmosphere. This change in the global climate would have disastrous results, including drought, coastal ooding and increased species extinction. Also, the scientists have discovered a hole in the ozone layer. The ozone layer is the only protection for life on Earth against deadly ultraviolet radiation from the Sun. Once the ozone layer is completely destroyed, all life on Earth will cease to exist, killed by the deadly radiation. The planet will become a barren rock devoid of all life. And when this happens the process of industrialisation would have to take the blame which has resulted in increased use of fossil fuels such as coal, petroleum and diesel.

The government cannot afford to compartmentalize education. It has to be emphasized that any country which does not have a good university education will never be listed as an independent country and will never be able to progress. Only countries prepared to tolerate a second rate and subjugate status in the world would neglect higher education. If India has had any position in the comity of nations in past, it was only because it had a better higher education than many of its Asian counterparts. This, clear emphasis on the higher education, however, does not imply that it should be supported and developed at the cost of primary and secondary education.

Although an eco-friendly process and one of the main ways to save the environment, recycling is not gaining pace in the industry. The process of recycling undergoes many processes. First is collecting and sorting of garbage. This requires a lot of manpower and tools which are expensive. Another disadvantage of recycling which makes it unlivable is that for the manufacturers, economically, the recycled material is not highly demanded since its quality is not as good as the original material. So if the marketing of recycled goods is not worthwhile; then the whole process of recycling can not be economically ef cient. Recycled products face other disadvantages as
well, such as short shelf life, dif culty in de-inking the dyed products and less durability etc.

The human civilisation stands on an edge of destiny. It lies today on the mercy of nuclear weapons which have the power to destroy us completely lest controlled wisely. In such a crisis situation, it is important to develop sensitivity towards basic values of life. It includes an explicit realisation that humans swim in an ocean where they
must swim together and sink together. At this juncture a single rotten sh would damage the ocean as a whole. Man can not afford to tamper with his loyalty to peace and international understanding which is the only way to deal with the situation. Anyone who does so, dooms the entire past, present and the future of the human civilisation.
