What are genetically modified (GM) plants give advantages of it?
Answers
Explanation:
Genetically modified (GM) is a technology that involves inserting DNA into the genome of an organism. To produce a GM plant, new DNA is transferred into plant cells. Usually, the cells are then grown in tissue culture where they develop into plants.
Advantages:
- More nutritious food.
- Tastier food.
- Disease- and drought-resistant plants that require fewer environmental resources (such as water and fertilizer)
- Less use of pesticides.

Explanation:
Genetically modified (GM) crops have many potential advantages in terms of raising agricultural productivity and reducing the need for (environmentally harmful) pesticides. They might also pose hazards to human health, from toxicity and increased risk of allergies, for example. However, particularly in Europe, regulations designed to ensure adequate safety of GM technologies may go too far.
Plant genetic engineering methods were developed over 30 years ago, and since then, genetically modified (GM) crops have become commercially available and widely adopted. In 2009, GM crops were being grown on 10 percent of the Earth’s arable land.
In these plants, one or more genes coding for desirable traits have been inserted. The genes may come from the same or another plant species, or from totally unrelated organisms. The traits targeted through genetic engineering are often the same as those pursued by conventional breeding. However, because genetic engineering allows for direct gene transfer across species boundaries, some traits that were previously difficult or impossible to breed can now be developed with relative ease.
So-called first-generation GM crops have improved traits. Herbicide-resistant soybeans and corn (maize), for example, can be “weeded” with herbicides that are more effective, less toxic, and cheaper than the alternatives. Cotton and corn have been modified to incorporate Bacillus thuringiensis (Bt) genes, producing proteins that are toxic only to larval pests. Crops can also be modified to ward off plant viruses or fungi. Even though the seed is more expensive, these GM crops lower the costs of production by reducing inputs of machinery, fuel, and chemical pesticides. In addition, due to more effective pest control, crop yields are often higher.

Important environmental benefits, such as controlling farm runoff that otherwise pollutes water systems, are associated with reduced spraying of chemical insecticides and highly toxic herbicides. Reduced mechanical weeding helps prevent the loss of topsoil. Health benefits result from reduced pesticide exposure for farmers and rural laborers and lower pesticide residues for consumers.
Where Bt crops have been grown in developing countries, the technology appears to often generate employment, because more workers are needed to harvest the significantly higher yields. One study in India suggests that Bt cotton produces 82 percent higher incomes for small-farm households compared with conventional cotton—a remarkable gain in overall economic welfare.
Recent research shows that direct and indirect effects of Bt cotton increase aggregate welfare by over $2 billion per year in India alone; a significant share of these gains go to rural households living below the poverty line. The annual gains of Bt cotton in China are also estimated in a range of $1 billion. Other developing countries where farmers use Bt cotton include Pakistan, South Africa, Burkina Faso, Mexico, and Argentina.
GM soybeans and corn, which are widely grown in North and South America as well as South Africa and a few other countries, also produce large aggregate welfare gains, currently estimated at $5 billion per year at the global level. Huge benefits are also projected for future GM crops that are more tolerant to drought or more efficient in nutrient use.
