ТЕМА №13 GENETICALLY MODIFIED FOODS: CURSE, BLESSING OR OTHER 

Nowadays most people eat genetically modified foods. But many of us do not know whether these foods are safe or dangerous for our health.  

Genetically modified (GM) foods are food items that have had their DNA changed through genetic engineering. 

For example: for the tomatoes and strawberry were more frost-resisting, they put into them the genes of northern fishes; for the wreckers didn't eat the corn, they can put a very active gene received from a poison of the snake.

I'll enumerate some: soybean, corn, canola, and cotton seed oil.

Genetically modified product can be meat. For example: The cattle get growth hormone. 

The generically modified plants have pluses. The chemicals in them collects less, than in their natural analogues. For example, chemicals in them collects less, than in their natural analogues. Some destroy  by themselves herbicide with the help of containing special ferment. 

Genetically modified foods are risky for the environment too. The ability of these types of crops plant to resist weeds, even fight back pests affect other organism of the environment.

There are violations of natural food chains can be in environment.

For last ten years of the generically modified products manufacture has got huge scales, especially in USA  

In Russia to grow these product is forbidden, but I think we get any way from other countries.
