Science is blessing. It is very useful for us. If you see there are many advantages in science. Without science there is nothing. Such as radio's, computers,laptops, machines which saves time and energy, calculators ,etc,. But it is the mind set of the people who are misusing it. Disadvantages such as sound pollution , air pollution, water pollution, earth pollution. Pesticides which cause severe harm to the soil. Toxic chemicals whuch mix in water bodies causes tge death of marine animals. So, it depends on the way which we use it. As far as my concern scuence is blessing. But we using is wrong way. So finally science is blessing.
