1MASTERS OF SCIENCEAbstract:The term GMC can be defined as Genetically Modified Crops can be defined as those plants theDNA of which has been modified by the use of genetic engineering methods. Insect resistantGMC can be defined as those crops which have been prepared by botanists in such a way thatthey are toxic to certain kinds of insects. The usage of GMC is controversial since according toseveral scientists GMC impose negative impact on the environment by destroying thebiodiversity. The aim of the research is to find out whether GMC are safe for the ecosystem ornot. Finally it has been found that the usage of GMC has imposed several positive impacts onthe environment and is safe for biodiversity.

3MASTERS OF SCIENCEIntroduction:Since the time immemorial, farmers are trying to minimize the negative impact of crop pests.Insects like nematodes, bacteria along with viruses and fungus causes immense destruction ofcrops that impose negative impact on the economy of a country. For instance, the Irish Potatofamine in the 1800s, had resulted in the death of more than 1 million individuals and a largescale of emigration (Azadi et al. 2015). In early centuries, farmers used to collect seeds onlyfrom high yielding plants as a preventive measure from pests. With the advent in geneticengineering, genes from insect resistance can be moved into plants. This technology is knownas Bacillus Thuringienis or Bt Technologies.With the emergence of genetically modified crops, the question whether genetically modifiedcrops impose positive or negative impact on the environment has raised. While GeneticallyModified Crops (GMC), has the ability to help the farmers to use fewer chemical insecticides,these crop may end up misbalancing the ecosystem. According to several scientists, GM foodsbear a special environmental threat and hence should be used carefully (Han et al. 2015). TheNational Research Council stated that improper or over usage of GM technology may leads todisastrous results. For instance, farmers who plants herbicide-resistant GM crops often give riseto herbicide-resistant superweeds. Apart from that, it has been also found that overplanting ofBt Crops has resulted in birth of a new breed off resistant insects in some fields. However, theNational Research Council is not able to convince that insect-resistant GMCs are inherentlyriskier. According to them, insect resistant GMCs are safe as long as they are properly used(Gurau and Ranchhod 2016).
