Food Industry. Food is one of the most important necessities for humans; we eat to live and at least most people are blesses with a meal a day, while some others can afford three or more. Independent of our culture and customs, dinning remains a vital aspect in different festivities across the world between and within families and friends.

Genetically Modified Crops and Food Security

Feed Your Mind Main Page. Genetic engineering is often used in combination with traditional breeding to produce the genetically engineered plant varieties on the market today. For thousands of years, humans have been using traditional modification methods like selective breeding and cross-breeding to breed plants and animals with more desirable traits. For example, early farmers developed cross-breeding methods to grow corn with a range of colors, sizes, and uses. Most of the foods we eat today were created through traditional breeding methods. But changing plants and animals through traditional breeding can take a long time, and it is difficult to make very specific changes.

Metrics details. What has long been suspected is true: genetically modified GM crops do have real benefits for the environment and for the economic well-being of farmers. The results confirm earlier and smaller studies and therefore are not unexpected. But they are particularly welcome for significantly informing the public debate on GM crops. Since the market introduction of the genetically modified FLAVR SAVR tomato in [ 1 ] and the successful sales of transparently labeled GM tomato paste by Safeway and Sainsbury supermarket chains from to , GM crops and food have become the center of public controversy [ 2 ].

Genetically modified crops: the truth unveiled

The genetic modification of food is heavily politicised and there are numerous arguments for and against the practice. Proponents of genetically modified GM food claim that it will increase food security, primarily by making agriculture more efficient, while detractors argue that the technology is potentially dangerous and the cultivation of GM food could have unforeseen consequences that will ultimately prove detrimental to food security. By examining the use of GM in plant and livestock agriculture, this paper will consider both sides of the debate. Ultimately, some varieties of GM food have the potential to strengthen global food security while others are likely to be self-defeating in the long-term. Genetic engineering, which involves the modification of the genetic makeup of living organisms, has been practiced for over 40 years and commercial applications have been available for the last two decades.

While selective breeding has existed for thousands of years, modern biotechnology is more efficient and effective because seed developers are able to directly modify the genome of the crop. Plants that are genetically engineered GE have been selectively bred and enhanced with genes to withstand common problems that confront farmers.

After the first agricultural revolution ten thousand years ago, people have gradually increased the yield by crossing different varieties of crops. As a result of multiple adaptations five basic food crops have emerged: rice in Asia, wheat in the Fertile Crescent originally from Ethiopia , maize and beans from Mesoamerica, and potatoes from South America that offers the nutritional base for 6. During the 21st century, agriculture will be confronted with great challenges. Due to population growth until more than nine billion people must be fed. Most of them will live in poor countries, still threatened with hunger FAO ; , b.

Слава Богу, разрешено хоть. Стратмор требовал запретить всяческий доступ, но Фонтейн настоял на. - В шифровалке нет камер слежения? - удивился Бринкерхофф. - А что, - спросила она, не отрываясь от монитора, - нам с Кармен нужно укромное местечко. Бринкерхофф выдавил из себя нечто невразумительное.

Я смогу ей объяснить. Она поймет. Честь. Страна. Однако в списке было еще одно сообщение, которого он пока не видел и которое никогда не смог бы объяснить. Дрожащей рукой он дал команду вывести на экран последнее сообщение.




The role of genetically modified (GM) crops for food security is the subject of public controversy. GM crops could contribute to food production.
