GM( Gene Modification) Rice.基因作物
三種GM rice的好處和壞處：
1，由于較少使用殺蟲劑所以對環(huán)境有好處;
反對：1，由于可以使Wild plant也產(chǎn)生抵抗力所以對環(huán)境有害
2，由于可在干旱地區(qū)使用所以可使貧窮農(nóng)民致富
反對：因為每年要買新種子所以不能
3，可以調(diào)控維生素A含量來提高營養(yǎng)。
反對：不是最好解決辦法，比如吃蔬菜更好。
The article introduced a kind of plant which called GM( Gene Modification) crop.
It has three major benefits
1. It is good for the environment because it has the resisit-gene. Using GM crop can reduce the use of pesticide.
2. It can help poor farmers around the world. GM crop can also have good yield in dry season which will profit the farmer.
3. GM plant can add missing nutrients for people in specific area. For example people eating a lot rice lack of Vitamin A, so GM rice which had added Vitamin A in it can help people gain what they missed.
The lexture totally disagreed in those three aspects.
1. If the resist-gene is got by the wild crop, it will grow out of control which bring more demage to the environment.
2. those GM crop can not help farmers economically because they need to buy those GM seeds every year instead of using the seeds they got from the last season. It is more costly.
3. The Vitamin A added in the rice is not enough. the more efficient way to deal with this problem is encouraging those people eating more vegetable like sweet potato.
