Most people, everyone, that I talk to seem to think the world as we know it is in deep trouble. Population overshoot, natural resources used up, climate rapidly changing for the worse, and people living beyond their income because they won’t ever have to pay off their debts. There is no tomorrow! Live for the moment! Spend everything you have for any pleasure you can get. Why worry? We will soon be dead! Some people I know look forward to the end of humanity because they claim we are ruining the world for all the other living things. Of course, humanity will progress toward the collapse of civilization if the people with these attitudes have their way. Groups of people are driven by fear, and the usual response to fear-driven motives is violence.
I don’t feel that we are doomed, only that we are at risk of calamity. It does appear to me, because of my personal history with H-bombs, that the calamity will be much worse than most people imagine, and that population numbers will drop back to the times of the Greek philosophers like Socrates, Plato, Aristotle, and Alexander. That doesn’t sound too bad until you realize that the population of the Earth at that time was only a hundred million or so, which is one-eightieth of our present population.
I believe, or at least like to believe, that humanity can, with the experience of a total collapse of civilization, turn their fear of that disaster ever happening again to a kinder world view. What we need is a new world view of what human life is about, based not on a proclaimed abstract love of people, but upon a society of people behaving with physically kind actions. We can learn to perform kind actions routinely, and we can learn to teach children that it is a good thing to actually do kind things for other people. And because we as groups are driven by fear, it is necessary to make obvious to the children, and to everyone else, that the result of not treating others with kind actions is the annihilation of the human species. That idea is annoying!
Cheer up! There is hope! It is a tiny hope because it runs counter to the impulses of natural humans to be purposefully kind.

Dear friend:
You have been listening to the fake NEWS too much where doom and gloom sell. Eventually it will poison your soul and you mind. You will be amazed how much your outlook improves without a steady diet of doom and gloom from idiots who are usually wrong.
Remember the 50’s and all the hysteria of the bomb? The USSR threatening; ‘we will bury you’? Remember the fears about the air, the water and pollution and how we would all die of poisons? Remember the ozone hysteria. Remember the Club of Rome predicting world wide famine that would destroy half the world in less than ten years? Remember the prediction that we only had ten years of oil and when the energy ran out in the sixties we would all starve? During the sixties many people took drugs to ease their fears of that certain horrible future and made foolish and unwise choices that ended their lives much too early. Remember when the best and the brightest college students at Harvard petitioned the university to stock suicide pills for use when the final end time calamity came? The doom and gloom hysteria never ends.
And yet, here we are seventy years later and life has never been better. All the doomsayers from the sixties were wrong. Have you ever wondered why they were wrong? Throughout recorded history, there have always been predictions of doom that never came to pass. Perhaps it might be wise to consider the possibility that our current prognostications are as wrong as all those made throughout human history. There is little doubt that eventually there will be some unexpected calamity in the millennia to come. However, the human race is resilient and will find a way to cope. It always has. Cheer up. Life is too short to fret about thing over which we have no control. Focus on the moment and make the world a better place one person at a time.
For this is a day the Lord God has made. Let us rejoice and be glad in it.
But, if you need a little doom and gloom predictions humor, to cheer you up, try this:

People place too much faith in the fake NEWS and not enough in themselves or the Creator (and/or nature if you prefer).
It seems you didn’t read carefully enough. He actually makes the point that it can be fixed. I grant you that many have predicted demises that didn’t happen as such, but that is not a reason to put on the rose-colored glasses and ignore the obvious trends that will, unchecked lead us to our destruction.
Having “faith” that some outside source, whether god or aliens or even “science” will fix it, some actual people will have to “do” the science to fix it, and regular people will have to implement the science.
These same arguments were used in the sixties posited by dope smoking Hippies whose philosophy of life smelled as bad as their music. The only thing that was actually done was more dope smoking and yet somehow nature worked it all out and we are all still here, happy and alive. The NEWS media has to sell doom and gloom because that is their only product that will sell (i.e. fear), but we don’t have to buy it, nor even watch it, if we are wise. We just spent trillions to stop global warming only to find out that it was really climate change that we are supposed to fret about. If we had spent nothing, the results would have been exactly the same (except for the loss of revenues for the media companies). We did the same thing with the Ozone crisis, remember? Fool me once . . . yawn.
