Allergenicity
In India, hundreds of laborers picking cotton and working in
cotton ginning factories developed allergic reactions when
handling the BT cotton. This didn’t happen with the non-Bt
varieties. [Ashish Gupta et. al., “Impact of Bt Cotton on
Farmers’ Health (in Barwani and Dhar District of Madhya
Pradesh),” Investigation Report, Oct–Dec 2005]
Hospital records: “ Show that victims of itching have increased
massively this year, and all of them are related to BT cotton
farming.” [The Sunday Indian, 10/26/08]](https://image.slidesharecdn.com/geneticallymodifiedfood-copy-170508054012/85/Genetically-modified-food-controversies-14-320.jpg)

- 4. What is GMfood? Genetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified in a way at does not occur naturally, i.e. through the introduction of a gene from a different organism.
- 5. Why GM food? Thereare like hundred reasons why we should cultivate GM food but we can summarise them in four point - 1. To get higher yield 2. To get better nutrient compound 3. To get extended shelf life 4. For efficient drug delivary
- 6. Why GM foodin Bangladesh? Bangladesh is an agricultural country and we have variety of crops as our soil is so fertile. But nowadays we cannot meet the needs because of increasing population and lack of cultivable land. That’s why our scientists have developed new varieties which are higher in yield and rich in nutritional value. Though it is a controversial topic , we are dependent on this. Bangladesh has successfully launched new variety of brinjal, cotton and rice. BT brinjal is an important topic of bangladesh considering GM food.

- 11. Evolutionary achievement ofGM food Bug Killing Corn This corn produces BT protein which kills bug of corn. The corn itself works as an insecticide.
- 12. Evolutionary achievement ofGM food BT Brinjal The Bt brinjal is a suite of transgenic brinjals (also known as an eggplant or aubergine) created by inserting a crystal protein gene (Cry1Ac) from the soil bacterium Bacillus thuringiensis into the genome of various brinjal cultivars. On October 30, 2013 with approvals from the ministries of Environment and Forests (MoEF) and Agriculture (MoA), the Bangladesh Agricultural Research Institute (BARI) received permission to release four varieties of Bt brinjal.

- 15. Out-crossing The movement ofgenes from GM plants into conventional crops or related species in the wild (referred to as “out crossing”), as well as the mixing of crops derived from conventional seeds with those grown using GM crops, may have an indirect effect on food safety and food security.
- 16. Super Weeds Super Weeds:A wild plant that has been accidentally pollinated by a genetically-modified plant and now contains that plant's abilities to resist herbicides and insects. Glyphosate is the chemical name for an herbicide. Certain invasive grasses and weeds have proven themselves to be resistant to glyphosate, meaning that the herbicide is no longer effective against these plants. Examples of weeds resistant to Glyphosate • Common Ragweed • Italian Ryegrass
- 17. GMOs are unhealthy TheAmerican Academy of Environmental Medicine (AAEM) urges doctors to prescribe non-GMO diets for all patients. They cite animal studies showing organ damage, gastrointestinal and immune system disorders, accelerated aging, and infertility. Human studies show how genetically modified (GM) food can leave material behind inside us, possibly causing long-term problems. Genes inserted into GM soy, for example, can transfer into the DNA of bacteria living inside us, and that the toxic insecticide produced by GM corn was found in the blood of pregnant women and their unborn fetuses.
- 18. Genetic engineering creates dangerousside effects. By mixing genes from totally unrelated species, genetic engineering unleashes a host of unpredictable side effects. Moreover, irrespective of the type of genes that are inserted, the very process of creating a GM plant can result in massive collateral damage that produces new toxins, allergens, carcinogens, and nutritional deficiencies.
- 19. GMOs harm theenvironment. GM crops and their associated herbicides can harm birds, insects, amphibians, marine ecosystems, and soil organisms. They reduce bio-diversity, pollute water resources, and are unsustainable. For example, GM crops are eliminating habitat for monarch butterflies, whose populations are down 50% in the US. Roundup herbicide has been shown to cause birth defects in amphibians, embryonic deaths and endocrine disruptions, and organ damage in animals even at very low doses. GM canola has been found growing wild in North Dakota and California, threatening to pass on its herbicide tolerant genes on to weeds.
- 20. Then why GMfood? Research has already demonstrated the potential to develop crops with increased nutrient-use efficiency, greater drought and flooding resistance, stronger disease and insect resistance and higher nutritional content and yield. Why should human society not use this ability to improve crops in order to feed all of our still-growing population while striving to minimize the impact of food production on the global environment? The current crops and practices are not adequate to meet the challenges of the future, and going back to methods of the past that were unable to feed even half of the current human population is not the answer. What technologies that were controversial when first introduced would we be willing to give up now: vaccines, antibiotics, vitamins, organ transplants, water treatment, sanitation, telephones, Internet, etc.? These scientific discoveries and technological advances have all contributed to the improved health and well-being of human society, but there is nothing more fundamental to the future of humanity than adequate and nutritious food. Given the challenges we are facing in this century, both socially and environmentally, we urgently need to apply our best science and technology to the most important thing that every human must do every day eat.
- 21. Though GM foodhave limitations but the current needs are dependent on this technology. We can only hope that one day we will be able to overcome the limitations and also can use the technology with safety.
