What are the pros and cons of genetically engineered crops?

The biggest advantage of genetically modified crops are
that these are developed to provide specific benefits like presence of some desired
characteristics in the output produces, greater yield, reduced growing cycle time.
ability to survive and grow well in adverse soil, water and other climatic condition.
All these characteristics lead to reduction in cost of growing the crops and increase in
realization from sale of the products.

However there are
some disadvantages are also associated with genetically modified crops. The biggest
negative point is that the products of genetically modified are not tested that
thoroughly, as a result these products may cause many unforeseen health hazard using
such products or even coming in contact with them. Similarly the genetically modified
crops themselves may pose unexpected dangers to other crops grown in the same area. Foe
example these crops may be more vulnerable to certain kind of pests and diseases causing
their rapid spread.

Another disadvantage of genetically
modified crops is due to the commercial practices adopted by manufacturers of some
marketers of seeds of such crops. They engage in practices like developing varieties of
crops that do nor produce seeds. As a result farmers are made totally dependent on
monopoly of the seed supplier. In the long run, such growth of monopolistic power in
hand of a few is not good for any economy.
