  Every year, around one million people die of mosquitoborne diseases according to the World Health Organization (WHO). This is why mosquitoes are considered one of the deadliest living creatures on the planet — not because they are lethal themselves, but because many of the viruses and parasites they transmit are
 In the absence of an effective vaccine for dengue fever, Zika fever, chikungunya and other mosquito-borne diseases, researchers have developed genetic strategies to reduce mosquito populations. One such strategy involves the release into the wild of genetically modified (GM) mosquitoes that express a lethal gene — a strategy believed to have little impact on the overall DNA of wild populations of mosquitoes
 The transfer of new genes from GM organisms to wild or domesticated non-GM populations is a key criticism of GM crops like soybean and corn. There are concerns that the introduction of GM genes into non-target species could have negative consequences for both human and environmental health.
 Oxitec, a company that spun out of research at Oxford University in the early 2000s, developed and trademarked GM Friendly™ mosquitoes (also known as strain OX513A of Aedes aegypti). These male GM mosquitoes have what the company describes as a “self-limiting” gene, which means that when these so-called friendly mosquitoes’ mate, their offspring inherit the self-limiting gene which is supposed to prevent them surviving into adulthood.
 In theory, when these mosquitoes are released in high numbers, a dramatic reduction in the mosquito population should follow. According to research published by Oxitec researchers in 2015, field trials involving recurring releases of Friendly™ mosquitoes demonstrated a reduction of nearly 95 per cent of target populations in Brazil. In these field trials, experiments were not performed to assess whether GM mosquitoes might persist in the wild.
 A recent study from the Powell lab at Yale University has since confirmed that some of the offspring of the GM mosquitoes didn’t succumb to the self-limiting lethal gene and survived to adulthood. They were able to breed with native mosquitoes and thereby introduce some of their genes into the wild population
 Meanwhile, the impact of mosquitoes carrying these new genes remains largely unknown. One significant worry is that a new breed of mosquito might emerge that is more difficult to control. These new genes could also potentially alter evolutionary pressures on viruses carried by mosquitoes, like dengue fever, in unpredictable ways. This includes potentially increasing their virulence or changing their host-insect interactions. These are hypothetical risks that have been raised by scientists, and reflect the need for further study.

Why are mosquitoes considered as one of the deadliest living creatures on earth?

Among those suffering from the global recession are millions of workers who are not even included in the official statistics : urban recyclers – the trash pickers, sorters, traders and reprocesses who extricate paper, cardboard and plastics from garbage heaps and prepare them for reuse. Their work is both unrecorded and largely unrecognized, even though in some parts of the World they handle as much as 20% of all waste.
The World’s 15 million informal recyclers clean up cities, prevent some trash from ending in landfills and thus, reduce climate change by saving energy on waste disposal techniques like incineration. In the developed countries they are the preferred ones since they recycle waste much more cheaply and efficiently than governments or private corporations can. In the developing World, on the other hand, they provide the only recycling services except for a few big cities. But as recession hits the markets Worldwide, the price of scrap metal, paper and plastic has also fallen. Recyclers throughout the World are experiencing a sharp drop in income. Trash pickers and scrap dealers saw a decline of as much as 80% in the price of scrap from October 2007 to October 2009. In some countries scrap dealers have shuttered so quickly that researchers at the Solid Waste Management Association didn’t have a chance to record their losses. In Delhi, some 80% of families in the informal recycling business surveyed by an organization said they had cut back on “luxury foods,” which they defined as fruit, milk and meat. About 41% had stopped buying milk for their children. By this summer, most of those children, already malnourished, hadn’t had a glass of milk in nine months. Many of these children have also cut down on hours spent in school to work alongside their parents. Families have liquidated their most valuable assets – primarily copper from electrical wires – and have stopped sending remittances back to their rural villages. Many have also sold their emergency stores of grain. Their misery is not as familiar as that of the laid-off workers of big name but imploding, service sector corporation, but it is often more tragic. Few countries have adopted emergency measures to help trash pickers. Brazil, for one, is  providing recyclers, or “catadores,” with cheaper food, both through arrangements with local farmers and by offering food subsidies. Other countries, with the support of non-governmental organizations  and donor agencies are following Brazil’s example. Unfortunately, most trash pickers operate outside official notice and end up falling through the cracks of programmes like these. In the long run,  though, these invisible workers will remain especially vulnerable to economic slowdowns unless they are integrated into the formal business sector, where they can have insurance and reliable wages. This is not hard to accomplish. Informal junk shops should have to apply for licences, and governments should create or expand doorstep waste collection programmes to employ trash pickers. Instead of sorting through haphazard trash heaps and landfills, the pickers would have access to the cleaner scrap that comes from households.

The need of the hour, however, is a more immediate solution. An efficient but temporary solution would be for governments where they’d have to pay a small subsidy to waste dealers so they could purchase scrap from trash pickers at about 20% above the current price. This increase, if well advertised and broadky utilized, would bring recyclers a higher price and eventually bring them back from the brink. Trash pickers make our cities healthier and more liveable. We all stand to gain by making sure that the work of recycling remains sustainable for years to come.

What measures does the author suggest to help the informal recyclers in the times to come?

The empty ‘Chyawanprash’ containers near the makeshift kitchen at the elephant camp say it all – that the elephants have been having a healthy, nutritious diet as (1) by the veterinary doctors.  The camp managers say that the elephants get to have the nutritious (2) twice a day – morning before bath and early evening, walk eight to 1 km on the walking track twice a day and have loads of green fodder. A few of these elephants also undergo special medication, if necessary. ‘Valli’, a female elephant from the Koodal Azhagar Perumal Koil, Madurai, and ‘Vedanayagi’ another female elephant from Bhavani, Erode, are two such elephants. Based on the veterinarians’ prescription, the managers are treating the two for foot rot disease.
 The elephants get to (3) their legs in a decoction of seven chemicals, a traditional formula, to get over the problem. The foot rot sets in when the elephants are obese, or stand on hard surface or bitumen-topped roads for long with very little movement.
 Likewise, two other elephants are also undergoing eye treatment to overcome the ‘watery eye’ problem. This occurs when the elephants’ living (4) is hot. The managers say that the ingredients of the food and the quantity given to the elephants (5) from one to another and are dependent on the age and gender.
 Based on the two, a body-mass-index of sorts is derived and that determines the food and the quantity. Right at the start of the camp, the managers have noted down the weight of each elephant.
 This will be compared to the (6) that they will record when the elephants exit the camp around the second week of January. The managers say that one important factor in the camp is giving green fodder, which the elephants (7) in plenty in the camp. For the weak elephants, the camp managers give twigs of ‘aal’, ‘arasu’ ‘athi’ trees and also ‘koondapanai’.

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.

 Governments have traditionally equated economic progress with steel mills and cement factories. While urban centers thrive and city dwellers get rich, hundreds of millions of farmers remain mired in poverty. However fears of food shortages, a rethinking of anti-poverty priorities and the crushing recession in 2008 are causing a dramatic shift in world economic policy in favour of greater support for agriculture.
 The last time when the world’s farmer felt such love was in the 1970s. At that time, as food prices spiked, there was real concern that the world was facing a crisis in which the planet was simply unable to produce enough grain and meat for an expanding population. Government across the developing world and international aid organisations plowed investment into agriculture in the early 1970s, while technological breakthroughs, like high-yield strains of important food crops, boosted production. The result was the Green Revolution and food production exploded. But the Green Revolution became a victim of its own success. Food prices plunged by some 60% by the late 1980s from their peak in the mid-1970s. Policy makers and aid workers turned their attention to the poor’s other pressing needs such as health care and education. Farming got starved of resources and investment. By 2004 aid directed at agriculture sank to 3.5 % and Agriculture lost its glitter. Also as consumer in high-growth giants such as China and India became wealthier they began eating more meat so grain once used for human consumption got diverted to beef up livestock. By early 2008 panicked buying by importing countries and restrictions slapped on grain exports by some big producers helped drive prices upto heights not seen for three decades. Making matters worse land and resources got reallocated to produce cash crops such as biofuels and the result was that voluminous reserves of grain evaporated. Protests broke out across the emerging world and fierce food riots toppled governments. This spurred global leaders into action. This made them aware that food security is one of the fundamental issues in the world that has to be dealt with in order to maintain administrative and political stability. This also spurred the US which traditionally provisioned food aid from American grain surpluses to help needy nations to move towards investing in farm sectors around the globe to boost productive for themselves and be in a better position to feed their own people.
 Africa, which missed out on the first Green Revolution due to poor policy and limited resources, also witnessed a 'change'. Swayed by the success of East Asia the primary poverty-fighting method favoured by many policy-makers in Africa was to get farmers off their farms and into modern jobs in factories and urban centers. But that strategy proved to be highly insufficient. Income levels in the countryside badly trailed those in cities while the FAO estimated that the number of poor going hungry in 2009 reached an all time high at more than one billion. In India on the other hand with only 40% of its farmland irrigated, entire economic boom currently underway is held hostage by the unpredictable monsoon. With much of India’s farming areas suffering from drought this year, the government will have a tough time meeting its economic growth targets. In a report Goldman Sachs, predicted that if this year, too receives weak rains it could cause agriculture to contract by 2 % this fiscal year making the government 7%GDP growth target look "a bit rich". Another green revolution is the need of the hour and to make it a reality, the global community still has much backbreaking farm work to do.           

What impact did economic recession of 2008 have on agriculture?

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

The interview may be conducted by letter and by telephone, as well as in person. Letter and telephone interviews are less satisfactory. Direct contact with an individual and a face-to-face relationship often provide a stimulating situation for both interviewer and interviewee. Personal reaction and interaction aid not only in rapport but also in obtaining nuances and additional information by the reactions which are more fully observed in a face-to-face relationship.

Adequate preparation for the interview is a “must”. Careful planning saves not only time but also energy of both parties concerned. The interview is used to obtain facts or subjective data such as individual opinions, attitudes, and preferences. Interviews are used to check on questionnaires which may have been used to obtain data, or when a problem being investigated is complex, or when the information needed to solve it cannot be secured easily in any other way. People will often give information orally but will not put it in writing.

The intention of the writer of this passage is to
