Genetically Modified Crops and Food Security

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. Biotechnology, of which genetic engineering is a part, is a relatively young field and it is yet to reach its full potential. Equally, however, the possibility of unintended or unforeseen problems arising from the technology remains and it would be irresponsible to rush into the widespread production of GM food without first testing the safety of each product.

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.

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. These include strains of wheat that are more resistant to drought, maize that can survive pesticides, and cassava that is biofortified with additional nutrients. In addition to resistance-based attributes and biofortification, some GM crops can produce higher yields from the same planted area. GM crops have the potential to strengthen farming and food security by granting more certainty against the unpredictable factors of nature. These resistances and higher yields hold great promise for the developing world and for global food security. Yet, controversy remains over access to this biotechnology, corporation patents on certain plant strains, and claims regarding the safety and quality of GM foods as compared to non-GM foods.

Transgenic Plants for Food Security in the Context of Development

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. The improvement of plants and livestock for food production and the use of different conservation techniques have been in practice as long as humankind stopped migrating relying on agriculture for survival. With the quest to grow more and better food to meet the demand of our fast growing world population, genetic engineering of crops has become a new platform in addition to plant breeding. Molecular genetics has been and is a very useful tool used to better understanding of genes underlying quantitative traits associated with increasing crop yields or improving food quality.

Analyzed the data: MQ SK. Wrote the paper: MQ SK. Conceived and designed the survey: MQ. The role of genetically modified GM crops for food security is the subject of public controversy. GM crops could contribute to food production increases and higher food availability. There may also be impacts on food quality and nutrient composition.

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. Most of these countries are also affected by global environmental changes GEC , and they will face more floods and droughts, a decline in biodiversity, and in the fertility of soils.

Genetically modified crops: the truth unveiled

We not only need to provide food and nutrition for a growing global population, but we must do so in the face of mounting environmental challenges. The global climate is changing, and land suitable for agriculture and food production is changing with it. Salinification and desertification, flooding and drought, and natural disasters threaten agriculture across the globe. With changing temperatures, meanwhile, come new risks from pests and diseases.

Social and Economic Issues – Genetically Modified Food

Наконец канадец опомнился. - Из консульства? - Его тон заметно смягчился. Беккер кивнул.

We apologize for the inconvenience...

Сделал он это как раз вовремя - убийца промчался мимо в ту же секунду. Он так торопился, что не заметил побелевших костяшек пальцев, вцепившихся в оконный выступ. Свисая из окна, Беккер благодарил Бога за ежедневные занятия теннисом и двадцатиминутные упражнения на аппарате Наутилус, подготовившие его мускулатуру к запредельным нагрузкам.

 Нет. Это был шантаж. Все встало на свои места. - Ну конечно, - сказала она, все еще не в силах поверить в произошедшее.  - Он хотел, чтобы вы восстановили его доброе имя.

 Вы хотите отправить его домой. - Нет. Пусть остается.  - Стратмор кивнул в сторону лаборатории систем безопасности.  - Чатрукьян уже, надеюсь, ушел.

Кроме того, - добавила она, - я хотела бы напомнить Стратмору, что Большой Брат не спускает с него глаз. Пусть хорошенько подумает, прежде чем затевать очередную авантюру с целью спасения мира.  - Она подняла телефонную трубку и начала набирать номер.

Скажите, что мы сдаемся. Немедленно! - Джабба достал из кармана мобильник.  - Давайте мне его номер. Я сам позвоню этому… - Не беспокойтесь, - прошептала Сьюзан.

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