Science and technology have been developing rapidly during the past ten years.Their developments have brought lots of benefits to mankind.Science has changed so much of today’s world.Due to science,we now live safer,more comfortable and convenient lives.However some people argue that while progress has brought us many time-saving machines,it has also brought us environmental pollution and energy shortage totally agree with it,Science has been responsible for pollution.Modern industry,as well as modern traffic conveniences,has created a serious problem of air pollution.The green earth is increasing very fast .is now threatening the existence of mankind .the population of the earth is increasing very fast .humans must make the earth support the increasing population.This has made it necessary for agriculture and industry to develop rapidly.Such a rapid development produces more and more waste,which goes into the water,the soil and the air.Some of it is made harmless.However,where there is too much of it,the poisonous waste may do great harm to the things around the people.From what I mentioned above,I believe that it is the development of science and technology that leads to the pollution of environment and shortage of energy.
