OGM's vs Agricultura Biologica

Na página da Scientific Alliance:

- OGM's

"The issues relating to GM crops are not unique and the testing of GM products for ecological and environmental risk can be compared to that of conventional crops. Globally, there have been tens of thousands of trials since 1986 and a huge number of market releases of GM crops such that since 1996, the major GM crops occupy over 150 million hectares annually and are grown by 5.5. Million farmers to date there have been no recorded cases of harmful environmental or health effects whatsoever of authorised GM crops and food productsderived from them"

- Agricultura biologica

Organisations promoting organic produce have claimed that organic food is healthier than conventionally produced food and better for the environment because it is free of man-made pesticides and chemicals. There is no scientific evidence for the former and only limited evidence in some situations for the latter.

However, organic farming allows the use of ‘natural’ toxic, persistent chemicals, such as copper sulphate and rotenone which are harmful to health. The UK Food Standards Agency headed by Sir John Krebs concludes that there is no evidence that organic food is healthier than conventionally grown produce.

Apesar de as evidências apontarem no sentido inerso os produtos biologicos têm posição de destaque nos nossos supermercados enquanto os OGM's se encontram banidos.
