SPEAKERS at a seminar expressed their concern that the cultivation of genetically modified (GM) rice would ruin ecological balance in the long run. They informed that the cultivation of GM rice is controlled or banned in the countries of Europe. The introduction of biotechnology gave rise to a sharp controversy as to whether GM food would be harmful or helpful for humans and nature. Proponents of genetic modification base their arguments on the need to feed growing world's population which has already crossed 6 billion mark and is predicted to double within the next 50 years. They say that GM foods promise to meet this demand.

According to them, through biotechnology it is possible to develop crops resistant to pests, diseases, cold and drought and even to salinity. Genetic engineering would make production of more nutritious crops possible. GM plants would also help keep pollution low. But according to critics of genetic engineering, GM foods would create hazards in the environment, human health and economy. Genetic modification may cause harm to other organisms like bees or butterflies that are essential for pollination of crops. This technology may lead to gene transfer to non-target species of plants and animals. Introduction of gene into a plant may create new allergens to cause life-threatening allergic reaction among the consumer. Should Bangladesh adopt bio-technology to grow sufficient food to feed the fast growing population? If this option is taken the country will have to take every precautions. GM crops must be tested on a case-to-case basis before introduction. Indiscriminate introduction of GM crops may prove counter - productive. Before adoption of biotechnology Bangladesh must ensure bio-safety and conservation of the natural system. Bangladesh has a bio-safety law. It needs to be enforced urgently.
