Science and technology has certainly helped each one of us in many different ways-such as helped in developing the many under developing countries into developed countries, helped in improved transportation system, also made it possible to visit and discover many places on earth as well as in space that was thought impossible before the development of the science and technology, but these are only advantages we also have the disadvantages such as the ozone layer depletion due to excessive use of chemicals, soil erosion due to deforestation, etc. Well I would certainly like to conclude by saying that science and technology is very important but it should also keep in mind the environment
