Anglais : NOTION PROGRESS

Since man cultivates plants and breeds animals, he makes them evolve by selecting the ones with the highest productivity. This evolution has made it possible to create new varieties or breeds that did not exist before and are improvements: better yields, better quality, better resistance to diseases, pests, drought. So we will talk about GMOs and alternatives that exist.

we can ask ourselves                                   And what are the advantages and disadvantages?

I- avantage

→ OGM : - it makes it possible to produce food more efficiently and cheaply.

- plants are more resistant to pests and diseases so plants need less insecticide and pesticide which is better for human life.

-Researchers are currently trying to develop GM foods containing more vitamins and nutrients. For example rice enriched with vitamin A. These GMOs would fill certain rates in the diet, especially in poor countries.
- look better to consumers

→ Oragnic Food:

II désavantage :

-> GMOS

→ Bio :  

Moreover
The price of organic foods is much more expensive than a conventional food. Indeed, there is little real scientific research on organic farming techniques; it is often difficult to obtain the necessary equipment, breeds and products. In addition, it is more difficult to react to unforeseen factors such as the sudden arrival of new pests or pathogens (germ, bacteria ...).
and finally, in most countries, agricultural and trade policy favors conventional agriculture.
