Genetically modified crops


Genetically Modified crops:
THW ban genetically engineered crops.
Background:

Genetically modified foods, also known as genetically engineered foods, are the latest contribution of genetic engineering technology. Genetically modified foods are made by inserting genes of other species into their DNA. Though this kind of genetic modification is used both in plants and animals, it is found more commonly in the former than in the later. There are a variety of reasons for developing genetically modified foods. For instance, some foods are genetically modified to prevent the occurrence of allergies after consumption, while some are developed to improve their shelf life. It is also been said that experts are working on developing foods that have the ability to cure certain diseases. Some of the genetically modified foods that are available in the market include cotton, soybean, canola, potatoes, egg plant, strawberries, corn, tomatoes, lettuce, cantaloupe, carrots, etc. Though developers and manufacturers of genetically modified foods ensure that there are various advantages of consuming these foods, a fair bit of the population is entirely against them. Let us look at some of the genetically modified foods pros and cons.

Pros:
  • One of the major advantages of genetically modified foods is that they help in controlling the occurrence of certain diseases. There are some foods that cause allergy to people when consumed. By modifying the DNA system of these foods, the properties causing these allergies are eliminated successfully.
  • It is also said that genetically modified foods grow faster than the foods that are grown in the traditional manner. Due to this, productivity increases, providing the population with more food. Apart from this, it is claimed that genetically modified foods are a boon in places which experience frequent droughts, or where the soil is incompetent for agriculture, due to which it is difficult to grow normal crops.
  • Though the seeds of genetically modified foods are quite expensive, the total cost of production is said to be lesser than the production of traditional crops. The main reason for this is that these foods have natural resistance towards pests and insects and so not much pesticides and insecticides have to be sprayed on them. This reduces the necessity of exposing genetically modified crops to harmful pesticides and insecticides, making these foods free from chemicals and environment friendly as well.
  • Genetically modified foods are said to be high in nutrients, and contain more minerals and vitamins than those found in traditionally grown foods. Other than this, these foods also taste better. Another reason for people opting for genetically engineered foods is that they have an increased shelf life and so there is less fear of the foods getting rotten quickly.
  • About 200 million acres of farmland worldwide are now used to grow GE crops such as cotton, corn, soybeans and rice. The most common GE crops are Soybeans, which represent 63% of all GE crops, Corn (19%), Transgenic Cotton (13%) and Canola (5%).iv The majority of genetically modified crops grown today are engineered to be resistant to pesticides and/or herbicides so that they can withstand being sprayed with weed killer while the rest of the plants in the field die.
Cons:
  • The biggest threat caused by genetically modified food is that they can have harmful effects on the human body. It is believed that consumption of these genetically engineered foods can cause the development of diseases which are immune to antibiotics. Moreover, according to some experts, people who consume such foods have high chances of developing cancer. Besides, as these foods are new inventions, not much is not known about their long term effects on human beings. As the health effects are unknown, many people prefer to stay away from genetically modified foods.
  • In many countries, manufacturers do not mention on the label that the foods are genetically manufactured because they think that this would affect their business. However, this is not a good practice as consumers do not get the chance to decide whether they should really opt for these foods.
  • Many religious and cultural communities are against genetically modified foods because they see it as an unnatural way of producing foods. Many people are also not comfortable with the idea of transferring animal genes into plants and vice versa. Also, this cross-pollination method can cause damage to other organisms that thrive in the environment.
  • Experts are of the opinion that with the increase of genetically modified foods, developing countries would start depending more on industrial countries because it is likely that they would control the food production in the time to come.
What is the current situation abroad?
The EU is delaying the planting of GM crops until they are proved to be safe. The US, Canada and Argentina are bringing a case in the World Trade Organization alleging that this delay is simply a trade barrier by another name. Given the absence of evidence of any harm from GM foods, the plaintiffs have every chance of winning the argument.
