Those people who throw away rubbish don't understand that thus they are slowly killing out planet. They pollute the rivers and air and even don't feel sorry. Air pollution is very dangerous because it can kill everybody. But people continue destroying our planet. They harm our forests, cutting it off for their needs. People must stop, they must think how they can solve this problem. For example we can recycle our rubbish, thus we will help our nature and we won't destroy the enviroment. we must protect our planet for ourselves and our future! People, please, don't close your eyes on environmental problems.
Practically in every field of study people have made huge progress in 20-21 centuries. Of course it has happened in medicine too. the aim of technological progress is the same as that one of medicine - to help people live better. And recent achievements in medicine make it possible for people to live longer, not to die so early. That means that technological progress must participate in medicine. For example different devices were invented, which are able to sustain people's life during operations. Less people die, more people survive. Why is it bad?
Some people are afraid of technological progress, and may be they are right. but if we use all out inventions carefully, nothing bad will happen.
