Technology: good and bad sides

Because technology is so important in society,

technicians,t echnologists,a nd engineers always have to think about values, that is, whether something is good or bad. Unfortunately, some technology has both positive and negative effects on society' Using mínerals such as oil, coal, iron, and uranium improves our standard of living, but can aiso pollute the air, water, and ground. The same rockets that allow space exploration can carry nuclear weapons. Road vehicles and planes allow fast travel but also cause accidental deaths and create global warming. The challenge for technology is how to increase the positive effects on society but reduce or eliminate the negative effects.
