Cloning has the potential to change society. For some,it’s a welcome development designed to make our lives easier. For others,it represents a threat to the health and balance of society,especially from a moral perspective(角度). Looking at these cloning pros and cons,it’s important to consider the scientific,financial,and social aspects of cloning processes.

From a scientific perspective,cloning can be considered major progress. Scientists aren’t limited by population. It’s also possible to clone pieces of living things.

However,cloning changes the natural order of life and death. Why should scientists have to treat an animal well in the lab if they can just make more? As a result,scientists may become lazy or careless with the living things they work on.

Cloning is a major business. Medical research groups have invested millions of dollars in making cloning possible. As a result,they can make big profits from selling cloning services to hospitals and the public. However,the wealth they achieve doesn’t mean that cloning itself is a profitable trial.

As a whole,cloning for society can be debated for hours. On one hand,you have religious groups,who say that cloning is wrong.

In 1975, George Carlin appeared on a popular TV show, Saturday Night Live, with his famous words about blue food. “Why is there no blue food? I can’t find blue food—I can’t find the flavor of blue! I mean yellow is lemon; orange is orange and red is cherry. Where is the blue food? ”

Well, Carlin pretty much has it right—there’s not no blue food, but there’s certainly not a lot of it. Fresh-picked blueberries are blue, though they become purple when they are turned into jam. The blue in blueberries—like the purple in grapes and the red in tomatoes—is found in nature. But it isn’t a hot color for food. People don’t seem to prefer blue food. Some diet programs even suggest that those determined to lose weight should make their food blue.

Eating, in part, begins with our eyes. Charles Spence—an experimental psychologist from Oxford University—points out that color can change our taste experience. Commonly, we consider red-colored foods up to 20% sweeter than they actually are; and green foods as being more sour. Spence suggests: human expectations may be influenced by our long history of watching - green fruits can become sweet as they grow up and turn red.

But what about blue? Except blueberries, much of the blue food we see these days is dyed blue artificially. Food producers argue that artificial color doesn’t do much harm to health. A lot of research shows that some physical problems of kids are related to food dyes—while other studies show no effects at all. Blue birthday cake or even blue-dyed chicken can be served on the dinner table. So what?
