the merits and demerits of science and technology

as the science and technology develops at an unprecedented tempo, our life is undergoing tremendous changes as well. but we have to look into the issue in two respects since science and technology is a double-bladed sword.

on the one hand, technology brings us more comfortable and convienent lifesyle. for instance, we can buy whatever we need on such platform as Taobao and Ebay without stepping out of home. besides, we can have access to any news or information online instead of reading newspaper or watcing TV, which are much more retarded than Internet.

On the other hand, science and technology can be evil as well so long as we don't pay much attention to such problems as the increasingly severe pollution around the world. Facotries produce products by means of the cutting-edge technology which causes much emmission into air and water, and finally hinder people's health and fitness.
