What is the relevance of science to man and the society?

Wow! Now this question could be a long written answer, but I'll condense it. Let's put this in bullets:

* Science in the food industry and in medicine has enabled humans to live longer lives. In fact perhaps in the well to do countries longer than nature intended. This is great for some individuals, but means a slow progression toward death with a sad life for others with diseases that would result in death earlier. Result a huge expensive industry for the medical professionals, and in some cases attorneys.

* Science in many of the disciplines is giving humans knowledge that was only speculated on in the past. Such as in genetics, the origin of the solar system and conditions on the planets and in archeology and anthropology. The sciences that help us discover sources of energy that were hard to get at before, both old and new as petroleum/natural gas with fracking, or wide generators and solar panels that are extremely efficient.

* The big one is computer science which has changed the way we communicate and interact with each other. It is fast, with still or animated pictures. The internet is an instant and magnificent reference library at your finger tips. So many people walking around with smart phones that have Internet, special applications, email, music and information in your pocket. This is good in so many ways, but society now spends less time just with face to face interacting.

Computer science keeps giving us faster and more capable computers that process data faster and faster. Helps scientific research. Computers even control our phones, electricity, water supply, natural gas, checking out at stores, doctor's office information. You make the list. This great! As long as there is not a massive failure in the networks or electrical grids.

* Finally, all of these advances in science are not filtering down to poor countries. We need to better share our resources both material and scientific. War is still around and science has made killing easier and less personal, and therefore too apt to occur. Take drones for instance It's like a video game except that the killing is real. Stealth enables weapon systems to come in and destroy and kill more easily with loss of life minimized for the invading country, but more dangerous for the country being invaded. Casualties can be limited for both countries if ethics are practiced. Of course ethics and science sadly don't go together.
