GM foods:harmful or helpful?

Hi, everybody!!! In this topic I would like to talk about Genetically Modified foods which became often used products in our world. And I guess that some of us have not even thought about harmful effects of these products. GM foods are "transgenic" life forms i.e organisms that cross unnatural gene lines (such as tomato seed genes crossed with potato genes). These organisms maturate the chain reaction inside of our bodies and decay it. And of course it leads to many deaths. Recorded Deaths from GM in 1989, dozens of Americans died and several thousands were afflicted and impaired (Mayeno and Gleich, 1994). Nowadays, in the shops and in the markets we cannot even distinguish these products one from another, and so most of the people even do not know what they buy. To avoid this displeasing situation I think all GM foods have to be labeled.
If they are labeled people will know what to buy exactly. Thank for attention!
