Time was when people looked heavenward and prayed, “Ye Gods, give us rain, keep drought away.” Today there are those who pray. “Give us rain, keep El Nino away.” 

El Nino and its atmospheric equivalent, called the Southern Oscillation, are together referred to as ENSO, and are household words today. Meteorologists recognize it as often being responsible for natural disaster worldwide. But this wisdom dawned only after countries suffered, first from the lack of knowledge, and then from the lack of coordination between policy making and the advances in scientific knowledge. 

Put simply, El Nino is a weather event restricted to certain tropical shores, especially the Peruvian coast. The event has diametrically opposite impacts on the land and sea. The Peruvian shore is a desert. But every few years, an unusually warm ocean current - El Nino - warms up the normally cold surface-waters off the Peruvian coast, causing very heavy rains in the early half of the year, 

And then, miraculously, the desert is matted green. Crops like cotton, coconuts and banana grow on the otherwise stubbornly barren land. These are the Peruvians’ anos de abundencia or years of abundance. The current had come to be termed El Nino, or the Christ Child because it usually appears as an enhancement if a mildly warm current that normally occurs here around every Christmas. 

But this boon on land is accompanied by oceanic disasters. Normally, the waters off the South American coast are among the most productive in the world because of a constant upwelling of nutrient rich cold waters from the ocean depths. During an El Nino, however waters are stirred up only from near the surface. The nutrient-crunch pushes down primary production, disrupting the food chain. Many marine species, including anchoveta (anchovies) temporarily disappear. 

This is just one damning effect of El Nino. Over the years its full impact has been studied and what the Peruvians once regarded as manna, is now seen as a major threat. 

The years of abundance is when  

Read the following passage carefully and give the answer of following questions.

The problem of water pollution by pesticides can be understood only in context, as part of the whole to which it belongs – the pollution of the total environment of mankind. The pollution entering our waterways comes from many sources, radioactive wastes from reactors, laboratories and hospitals; fallout from nuclear explosions; domestic wastes from cities and towns; chemical wastes from factories. To these is a added a new kid of fallout - the chemical sprays applied to crop lands and gardens, forests and fields. Many of the chemical agents in this alarming melange initiate and augment the harmful effects of radiation, and within the groups of chemicals themselves there are sinister and little - understood interactions, transformations and summations of effect.

Ever since the chemists began to manufacture substances that nature never invented, the problem of water purification have become complex and the danger to users of water has increased. As we have seen, the production of these synthetic chemicals in large volume began in the 1940’s. It has now reached such proportion that an appalling deluge of chemical pollution is daily poured into the nation’s waterways. When inextricably mixed with domestic and other wastes discharged into the same water, these chemicals sometimes defy detection by the methods in ordinary use by purification plants. Most of them are so complex that they cannot be identified. In rivers, a really incredible variety of pollutants combine to produce deposits that sanitary engineers can only despairingly refer to as “gunk”.

Start-ups troubled by the so-called angel tax may soon receive some (A)______from the government. On Monday, the Centre set up a five-member working committee to look into revising the (B)norms of the angel tax imposed on start-ups. The tax, which was first introduced in 2012 to curb money-laundering through the (i) at bloated prices, has caused a lot of anguish among start-up investors in the country. Start-up owners have complained that income tax officials have asked many start-ups to cough up money when they try to attract capital into their entities by issuing new shares. For its part, the IT department fears that start-ups may be used as convenient tools to launder illegally acquired money, so a tax on investments beyond a certain threshold is (ii). (C) But while the (1) unintended of such an angel tax may be (2) benefits, the arbitrary nature of it means the cost of (3) intent consequences could be larger than the supposed (4) justifiable. In trying to curb money-laundering, Section 56(2)(viib) of the Indian Income Tax Act, 1961 gives income tax officials a free hand to harass even genuine start-ups looking to raise investments for their growth. Under the Act, the IT department is free to arbitrarily decide the fair value of a company’s share and tax start-ups if the price at which their new shares are sold to investors is higher than the fair value of these shares. The broad-brush tax on all investments means an unnecessary cost is (iii)community simply because of the lack of better means at the government’s disposal to tackle black money.

The committee set up by the government will, among other things, consider raising the threshold beyond which new investments into start-ups will be taxed. It is expected that start-ups with aggregate paid-up share capital and share premium of less than ₹25 crore, against the previous threshold of only ₹10 crore, will not be taxed while attracting new investment. This would definitely make life easier to a certain extent for angel investors and start-ups. But it will not address the real problem with the angel tax, which has to do with the unbridled power that it vests in the hands of the income tax authorities. Investors, foreign or domestic, may become wary of investing in new ideas when they are taxed while risking money on untested ventures. So the government should look to withdraw the angel tax and focus instead on building the capability to better identify and rein in illegal wealth. Otherwise it risks killing the nascent start-up ecosystem in the country.

Recent advances in science and technology have made it possible for geneticists to find out abnormalities in the unborn foetus and take remedial action to rectify some defects which would otherwise prove to be fatal to the child. Though genetic engineering is still at its infancy, scientists can now predict with greater accuracy a genetic disorder. It is not yet an exact science since they are not in a position to predict when exactly a genetic disorder will set in. While they have not yet been able to change the genetic order of the gene in germs, they are optimistic and are holding out that in the near future they might be successful in achieving this feat. They have, however, acquired the ability in manipulating tissue cells. However, genetic misinformation can sometimes be damaging for it may adversely affect people psychologically. Genetic information may lead to a tendency to brand some people as inferiors. Genetic information can therefore be abused and its application in deciding the sex of the foetus and its subsequent abortion is now hotly debated on ethical lines. But on this issue geneticists cannot be squarely blamed though this charge has often been levelled at them. It is mainly a societal problem. At present genetic engineering is a costly process of detecting disorders but scientists hope to reduce the costs when technology becomes more advanced. This is why much progress in this area has been possible in scientifically advanced and rich countries like the USA, UK and Japan. It remains to be seen if in the future this science will lead to the development of a race of supermen or will be able to obliterate disease from this world.
