1) Technology has resulted in various forms of pollution that threaten human life and the environment, such as chemical pollution from factories, vehicles, and air conditioning systems that damage the ozone layer. 2) Technology also has the power of destruction if used wrongly or for purposes of war, as seen with atomic bombs and nuclear weapons that can destroy millions of lives. 3) The potential hazards of future technologies are unknown and not well-researched, as seen with human cloning, which could allow cloned people to be controlled to commit crimes if developed further. Technology may pose unknown threats to humanity.
