Yes, you are right. Factory farms in the US use hormones to promote growth and milk production in beef and dairy cattle, and factory farms has the risk of contamination of the meet. technology is a double-edged sword, on the one hand, it is good for human, on the other hand, it maybe could hurt human.

> > If you can grow a chicken in 49 days, why would you want one you got grow in three months, human can make more money in their pocket. There are no seasons in the supermarket, there are tomatoes all year round, when tomatoes are green pick it up and ripened with ethylene gas. All of these look like tomato, but it is kind of notional tomato. Technology and science always change our life style, when you face a unnatural 49days grow up chicken, Do you want to eat it?
> The natural vegetables means high price now in the supermarket. And the consumer want to choose the cheap one. So the eat style is changed easily by the producer. We need something such as education for the consumer to let them know which is better. If the consumer has a demand of buy natural goods and refuse to buy the industrial ones. The food industry may be changed.
