Introduction:
The genetic material of living organisms has been altered by the use of modern biotechnology for beneficial use are known as Genetically Modified Organisms (GMOs). These organisms introduce the traits in crops that are beneficial for resistance against pest, higher yields and stress tolerance. Over the past 3 decades, GMO crops have became an important part of crop production globally, and their influence on agriculture, environment, and society continues to grow. It is a promising and beneficial tool for scientists to address global food challenges, but public opinions are still mixed because of safety and ethical issues.
How GMO Crops Are Developed:
1. Identification the desired trait:
l Find an organism which has beneficial and desired trait naturally, such as a soil bacterium that produces a natural insecticide.
2. Copy the gene:
l Identify and copy the specific gene that has desired trait.
3. Insert the gene into the plant:
l Insert the gene into the plant by using a gene gun, bacterium or Genetic engineering tools (CRISPR/Cas9).
4. Grow and test the new plant:
l Then grow the plant and then test it to make sure that it has new trait and performance before commercializing it.
Positive Environmental Impact:
GMO crops can actually be beneficial to the environment if managed responsibly. The less use of pesticides will result in soil improvement and water quality which can produce higher yield, which means that more food from the same land.
Benefits of GMO Crops:
· Increased yield and farmer profits
· Reduced the use of pesticide for example “Bt-cotton”, it produces it’s own insecticide.
· Enhanced nutritional content genetic modification can increase the nutritional value of crops. A notable example is “Golden Rice”, engineered rice to produce beta-carotene, which the body converts to vitamin A, helping to address vitamin A deficiencies in some regions.
· Improved crop resilience against environmental stress (het, drough, salty soils etc)
· Environmental benefits as the need of pesticides can be reduced.
Challenges in GMO Crops:
1. Environmental concerns with GM crops
Impact on non-target organisms.
Development of super weeds and resistant pests.
Reduction in biodiversity.
2. Economic challenges associated with GM technology
Increased cost of farming.
Corporate control and intellectual property issues.
Market access challenges.
3. Ethical and perception challenges
Public concern about food safety.
Religious and cultural considerations.
Perceptions of unnaturalness.
4. Health and safety challenges
Allergenicity.
Antibiotic resistance.
Unknown long-term effects.
Toxicity.
5. Health and safety challenges
Allergenicity.
Antibiotic resistance.
Unknown long-term effects.
Toxicity.
Conclusion:
Globally agriculture has been influenced by GMO crops by bringing enhancement in yield, improvement in nutritional value, and reduction in the need of pesticides. The promising solutions are offered to the problems like insecurity of food, malnutrition, and environment-related challenges. But because of environmental concerns, economic issues, and public mistrust there is need for careful regulation and long-term research. With responsible use of GMOs and balanced policies, this technology can continue to play a vital role in providing food to growing world population alongside supporting sustainable agriculture.
