Biodiversity and transgenic food

In Europe it exists " the principle of precaution".

This principle tells that it isn't possible to introduce a species if there is some suspicion of danger for human health or for environmental health.

The farming of GMO plants is a danger because these plants can change the genetic inheritance of wild plants.

And the men?

What is the tolerable risk for the human society?

In Europe, North America, Australia (the rich countries) there is many food. It isn't true that today there is more food because there are the GMO plants.

Infact the multinational societies work only five or six plants and only two kinds of genes, because these are more interesting in the business.

The poor countries (Africa, South America..) need food without much money (like it is necessary to buy from multinational societies the seems, the pesticides and so on...).
