Technology and Science

I think in life when you want something, you always have to sacrifice something else. That seems to be true between science and technology; nature or man-made. To me, there should be a balance between Science and Technology. A life like Thoreau would be too simple for an average human, even with just a black out of electricity, many people would think "Its the end of the world." Having too much Technology would also be bad for there is no nature, we won't be able to survive without something call oxygen. Car and factories are slowly destroying our environment by their output of gases that is harmful to the human bodies. Moreover, science or technology can be good or bad, it only differs in the personal opinions.
