GMO

GMO is to modify, to fix, to splice, to recombine the genes for new organisms or much adoptable species.The technology of GMO is mainly applied in food supplies, such as vegetables, crops and animals, and medical care.

The positive side of GMO is evident.In the agriculture field, GMO foods can increase crop production, food quality and the diversity of species, for instance, more drought-resistant plants.And in the medical field, it could produce special elements, as some proteins, and even organs to treat some certain diseases.

However, the negative side of GMO is uncertain.It may do harm to some insects and human body.It may also affect the growth of the surrounding plants and animals, and even may cause biological pollution and destroy the local ecosystem.

By the end of 2013, the GMO plantation areas were expanded to 170 million hectares in the world and there are about 4 million hectares in China.And whether GMO is safe, there is no certain evidence.The maturity and benefits of genetic technology can never be justifiable for its wide application.

So in my part, we can never be too careful in the spreading of GMO.
