in humans, genetically modified plants or organisms are widely used for genetics engineering technology enhanced the new production of foods to save and healthy the ecosystem biodiversity. The possible emergence of allergies to GM-related foods and toxicity from GM crops are the two most significant GMO dangers to people. so I can provide awareness to human being save your life. Genetic modification is a special set of gene technology that alters the genetic machinery of such living organisms as animals, plants or microorganisms. Combining genes from different organisms is known as recombinant DNA technology and the resulting organism is said to be ‘Genetically modified (GM)’, ‘Genetically engineered’ or ‘Transgenic’. In instances, the product is directly consumed as food, but in most of the cases, crops that have been genetically modified are sold as commodities, which are further processed into food ingredients.
Experts are working on developing foods that have the ability to alleviate certain disorders and diseases. Though researchers and the manufacturers make sure that there are various advantages of consuming these foods, a fair bit of the population is entirely against them. GM foods are useful in controlling the occurrence of certain diseases. By modifying the DNA system of these foods, the properties causing allergies are eliminated successfully. These foods grow faster than the foods that are grown traditionally. At times, genetically engineered food crops can be grown at places with unfavorable climatic conditions too. A normal crop can grow only in specific season or under some favorable climatic conditions. It is known that the main concerns about adverse effects of GM foods on health are the transfer of antibiotic resistance, toxicity and allergenicity. The safety of GM food is a hot topic, as are questions about how to label it, whether agricultural biotechnology is necessary to address world hunger now or in the future, and more specifically, questions about intellectual property and market dynamics, the environmental effects of GM crops, and the role of GM crops in industrial agriculture more generally.

3. What is GMP (genetically
modified plants) ?
Genetic modification (GM) is the area of biotechnology which concerns itself
with the manipulation of the genetic material in living organisms, enabling them
to perform specific functions.
Genetic modification of plants involves adding a specific stretch of DNA into the
plant's genome, giving it new or different characteristics. This could include
changing the way the plant grows, or making it resistant to a particular disease
Genetic modification in plants was first recorded 10,000 years ago in Southwest
Asia where humans first bred plants through artificial selection and selective
breeding. Since then, advancements in agriculture science and technology have
brought about the current GM crop revolution.
4. Emerging issues of GM plants
• Among the potential risks are pests becoming resistant, crops gaining
weediness and GM foods posing safety issues to both human and animals and
these are studied extensively. This has resulted in science-based risk
assessment and management that safeguard safety to humans, animals and
environment.
• GMO plants might have a different balance of toxins, increasing the risk of
harm to humans. Specific health concerns include an increased risk of cancer
and infertility, although research on the risks of GMO plant toxins is very
limited.
5. Environmental issues
• environmental impacts associated with using crop biotechnology
(specifically genetically modified crops) in global agriculture.
• It focuses on the environmental impacts associated with changes in
pesticide use and greenhouse gas emissions arising from the use of
GM crops since their first widespread commercial use 22 years ago.
6. Development of insect's resistance
• The use of Bt crops is
that it will lead to the
development of
insect's resistance to
Bt toxins.
9. Biodiversity changes
A major concern of genetically modified organisms is that
they will cause reduced genetic diversity of plants and
animals in the environment.
14. Ethical issues
• Five sets of ethical concerns have been raised
about GM crops:
1. potential harm to human health;
2. potential damage to the environment;
3. impact on traditional farming practice;
4. excessive corporate dominance;
5. and the 'unnaturalness' of the technology
15. Conclusion
• It is known that the main concerns about adverse effects
of GM foods on health are the transfer of antibiotic
resistance, toxicity and allergenicity. There are two
issues from an allergic standpoint.
• Issues of concern include: the capability of the GMO to
escape and potentially introduce the engineered genes into
wild populations; the persistence of the gene after the
GMO has been harvested; the susceptibility of non-target
organisms (e.g., insects which are not pests) to the gene
product
