GMF

GMF can have some benefits, like:
- Crops can be genetically altered to resist to pests, so they need less pesticide and they resist more to climate changes;
- Increase massive production;
- Growth of "perfect living beings";
- Their nutritional value can be altered to satisfy the hunger in poor continents, like Africa and in some parts of Asia.

But GMF can have some disadvantages too, like:
- GMF can cause some allergies;
- Crops can be affect by a disease that they can not fight because in the genetic modification they lost genetical variety so they don't have power to fight the disease so it causes massive destruction of the crops;
We don´t know what are the risks of the comsumption of the GMF and the risks to the enviorenment.

GM food is a new so scientists have a short space of time to test it and say if it is good to consume or not . Probably just a few years latter we will know if it is safe or not.
