Nowadays we can get lots of benefits from science and technology, for example, medicine, transport and communications. If someone gets a disease, there is enough medical knowledge and good medicine to treat them or make them live longer. Secondly, modern transport is more and more convenient, fast and comfortable. In addition, information technology can help us contact other people everywhere and anytime, especially when you use the Internet. It also allows shopping and anything you want to do without having to step outside our home.
However, advances in science and technology also have negative effects. For instance, the cause of air pollution in the world is too much transport. And it also causes global warming and makes people unhealthy. If we always use the Internet or mobile phone to contact, we will not do exercise outside and get farther away from other people. On health care, drugs misuse can also influence people’s health.
To sum up, we have made great progress over the last hundred years but there still many important issues to deal with. This might be considered a better time to live than any previous age but it must be that people are healthier and happier than ever before. And hopefully the future will be better
