Question

Plx explain advantagws of GM crops

Answer 1

Advantages of Genetically modified crops

i) Increase tolerance to abiotic stresses for example drought , pH of soil, temperature


ii) Reduce reliance on chemical pesticides as pesticides are harmful for human body.


iii) Increase the qulaity of the yield produced for example Golden rice is vitamin a enriched coded by beta carotene.


iv) Increase the efficiency of mineral usage by plants i.e. the manure that is given and the minerlas from soil are used more efficiently.


v) helps the crops resistant to pest and insects i.e. Whenever the pest and insect attack on crop,eventually they are killed

1. They are a technology that has already been going on for many years.Genetic modification and engineering is nothing new, where people have been already manipulating crops and food formany years, using methods that range from classical selection to fermentation.It is just the latest form of biotechnologythat is using the most precise method known. Basically, creating these crops is different from the traditional methodsof plant breeding, as it transfers genes from one species to another, crossing biological barriers.2. They are mostly believed to be safe.Proponents say that there are actually no inherent differences between food items produced from natural crops and those from genetically modified crops, similarly containing DNA that comprisedof nucleotides. This technology works by moving a piece of DNA from one plant breed into another, without introducing a foreign substance and with the new gene merely prompting themodified crop to show a desired trait. Also companies wishing to release a product or seed from a genetically modified crop are required the safety of these things. And if a certain product was created from an organism that contains a known allergen, it is required to undergo some tests for safety.3. They have improved quality and taste,as well as increased nutrients.Genetic modification in crops allows flavors of its products to be improved. For example, pepper can become spicier, corn can become sweeter and bitter gourd would become palatable without losing their original nutrients. Better yet, this technology makes it possible to enhance the vitamin and mineral content of food, providing benefits to consumers. This advantage is especially important to people in developing countries, who do not always have access to essential nutritional resources.4. They help ease the environmental impact by human activities.With the way it is practiced today, agriculture sometimes damages the environment, like any other human activity. Now, genetically modified cropscan help ease such negative impact by creating plants that are insect resistant, allowing farmers to dramatically reduce the use of insecticides. Also, the technology can create next-generation seeds that will allow farmers to maintain high yields, while using fewer amounts of chemical fertilizer and water. While critics point out the creation of super pests and weeds, which are highly possible, these dangers can be prevented and are manageable.5. They can help reduce world hunger.With genetic modification, even the smallest subsistence farmers will be able to produce larger, more reliable andprofitable crops for the market, as well as able to grow more food for their families. This means that we will be able to directly address the problem of hunger and malnutrition among poor consumers, especially in the developingcountries. In the long run, genetically modified crops are considered to be a solution to ensuring that food production can keep pace with the growing population, which is expected to double 12 billion by 2050. The rate of growth of food production has declined in the past decade, with the latest round of increase driven by Green Revolution methods, such as using high-yielding hybrid seeds, extensive amounts of fertilizer and pesticides. However, thesetechnologies do not have the capability to support food production growth for the coming decades without resorting tothings that can severely damage the environment. Now, GM crops are believed to be able to support such growth.
