<ul><li><p>Genetically Modified Crops A Brief Study</p><p>After the 20th century green revolution dawned the era of genetically modified crops. In 1994, the worlds first genetic modified crop, a delayed ripening tomato from Calgene, was grown and consumed in an industrialized country. The world has not looked back since then. There has been a 100-fold increase in the area of arable land planted with genetically modified crop, from 1.7 million hectares to 175.2 million hectares in 2013. Several developing countries are also growing genetically modified crops along with industrialized countries like USA.</p><p>Developing Genetic Modified Crops</p><p>Genes are transmitted from one living being to another during a process called genetic engineering; and this is how the genetically modified crop is created. Introduction of transgenes into plant genomes is performed by one of the two methods: </p><p>1) A gene gun shoots DNA that has been smeared onto tiny particles, into the plant cells; some of this DNA gets mingled with that of the host plant.</p><p>2) Desired genes are introduced into the recipient plant using a bacterium.</p><p>Once this activity is performed, the genetic modified crop usually displays certain traits it did not possess earlier, like improved resistance to weeds, pests and disease, new nutritive elements and so on. </p><p>In the US, soybeans, corn, and maize are the most commonly produced genetically modified crops.</p><p>Why Genetically Modified Crop?</p><p>Though the process was introduced by developed countries, we see that it is the developing countries that are producing genetically modified crops in a big way. This is because of the acute disparity between the population growth and the food supply that exists in those countries. Genetic modified crops have certain advantages like:</p></li><li><p> High crop yields vis--vis conventional methods may help solve food crisis Higher nutrition value of crop Reduced cost and increased profit Sturdier crops need fewer chemical pesticides, fungicides and so on, which is good for the environment</p><p>How safe is genetic modified crop?</p><p>This is the debate that is raging in many countries. Genetically modified crops have not yet been around long enough for scientists to accurately measure the consequences of their consumption on human health. But many environmentalists, scientists and traditionalists are against such crops citing possible damage to vital organs, introduction of allergens into crops and the possibility of genetic modified crops transferring their new traits to wild plants, creating super-weeds.</p><p>Trivedi Science and Genetic Modified Crops</p><p>Mr. Mahendra Trivedi was greatly disturbed by the prospect of mass production of potentially unsafe food for human consumption, but increasing crop production was a very real need. So he decided to use his powerful ability to perform Energy Transmission(s) to find an answer. Without resorting to any chemical, he was successful in enhancing crop yields by up to 500% in several varieties of plants and seeds, purely with his mental prowess. Known the world over today as The Trivedi Effect, this is a wholesome, natural, non-invasive phenomenon whereby his thought process cause significant atomic changes in animate and inanimate things to make them realize their full potential. In the US, he successfully used this phenomenon on crops like blueberry, soybeans, lettuce, carrots and ginseng.</p></li></ul>
