Wake Up
You make hysterical assertions with NOTHING to back it up. I've been around over half a century and things were FAR WORSE in the 1960's when America was coming apart at the seams, cities were burning from race riots and the war against the war in Vietnam, or the '70's when terrorism was 10 times more frequent, murder rate at least double, mass starvation the norm in many parts of the world, we were constantly worried about "today maybe the end of the world" as nuclear holocaust was always imminent....or the '80's when inflation was up to 14% and unemployment rampant. Travel was far more dangerous. Or how about earlier when polio killed and crippled children everywhere in the USA, I saw the results and it wasn't pretty. We have it so damned easy today it's laughable to compare. Things are far from perfect and it's fine to focus on our problems and flaws but tell a gay or a black person that things are WORSE now. Get a grip!
Do you have any idea what the environment was like prior to the 1980's? Our rivers (in the USA) were so polluted they would catch on fire, city smog gagged you and burned the eyes it was thick, stinky and brown, and lethal, acid rain was rampant, on and on.

@Jacob Zondag Supernova's are one of the most violent happenings in the universe, they briefly outshine an entire galaxy of 100's of billions of stars combined, we can see them across the universe. They also create most of the heavy elements where as the sun stops at iron which is too stable to easily fuse and ends the process unless the mass is great enough whence supernovas happen. Those explosions inject huge areas with all the elements we and Earth are made of. The old saying 'we are star dust' is literally true.
Some of the heaviest elements are probably not created even in supernovas however, gold, platinum group, etc., are probably only created in neutron stars colliding with eachother...my current understanding anyway.
About once per century or so we can expect a supernova in our galaxy, the nearest one ready to detonate, many times the size of the sun(sometimes pronounced 'Beatle juice')is the orange looking star in the Orion constellation and expected to detonate soon, with in a million yr.s or so, it's axis of rotation is fortunately not lined up with us or we could be in trouble with that one, could sterilize Earth, strip the atmosphere, as they emit extreme jets of high energy radiation from the poles. This is the reason that the galactic "habitable zone" is considered not near the center of the galaxy where stars are dense and explosions relatively common. ((pardon if that's TMI))
