In favour of Genetically modified food

In our opinion, genetically modified (GM) food is good. We think that, because we consider that if we use genetically modified crops we will have enough food for everybody in the all planet. The genetically modified crops are very resistant to diseases
In favour of cloning animals

We think that to clone animals is a scientific and good progress because it can help to cure a lot of diseases. If the scientists mix genes of different animals, they can create animals which produce more milk and more meat. And it is good for humans, because they will have enough food.


What are genetically-modified foods?

The term GM foods or GMOs (genetically-modified organisms) is most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques.

Cloning animals

First taken the DNA of the sheep A , and with a technological process pass their genes to ovulate of sheep B. Then fertilize ovulate of sheep B. After that, implant it in uterus of sheep B. It is developed and we have a clone of sheep A.

Dolly sheep

Dolly was the first mammal to be cloned from an adult somatic sell, using the process of nuclear transfer.
