Minacious watched too much movies. This point of view is SO pessimistic I really wonder if you're relying on true objective knowledge and you're biased from the beginning or if you're really biased by the partial postulates that lie in your memory.
The global situation of the civilization keeps improving over the centuries, the fact you can quantify "bad" things happening, or "bad" things being perpetuated (wars and shit) isn't sufficient to sustain conjectures like that. If we were in a context of Cold War, you'd be allowed to critically think that way, but we're past that kind of context since decades ago.
The more the time passes, the more we live confortably, the more extended the civilization and democracy becomes, etc. And I think "pessimistic seers" like you existed since the existence of Reason, just like a disregard of the youth as a "new generation full of bad moral bs", just like Socrates considered the young people as impolite, disrepectful, and all.

That is really naive to fall in this kind of biased opinions with really little things that may explain this thinking. It is realistic to think that the civilization will go on without a major breakdown in the two next millenia because it had never been majorly severed like that. But you may be thinking the civilization will end because of the human being because "we have more technical means to do it than before, we can even blow up the whole planet with the weapons we have". Some dispositions may effectively cause us to pollute the planet and all, but you're making a slippery slope thinking that "this is going on like that, then this will be going on like this, and this, and this" because that's a totally gratuitous conjecture and the relation between the assertions is only ensured by the slim causal correlation they have.
Also, thinking that, because we possibly can make this happen, we will make this happen one day or another is an appeal to probabilities and is another logical fallacy.

We've got past some great risks just like the Third Reich or the Cold War, and the world is running greater than ever. We didn't magically overcome these, this is the intelligence and the maturity of the human being as a collective force that solved these problems. And heck, at the time, nothing allowed anybody to think there was a tangible hope.
No, really, we may pass through some major problems, but nothing in which the civilization will sink ; because the capability for the human being to solve its problems made him achieve the world in which we live in today. And just don't let your mind bias yourself by thinking we may live in a "rotten world" because once again, no living being on earth is more conscious of its own problem than those of the human race.

tl;dr Try to relativize how you're viewing the world because this opinions is really naive and doesn't correspond critically with how the world is doing currently and how the world did in any time of the History.
