When will humans become extinct & why ?

Question

Overcrowding, wars, lack of food, pollution... what do you think ?

Answer 1

Like any other animal, when we fail to adapt to the environment.
I don't see humans dying out anytime soon. Oh, there will probably be a massive die off in 20-30 years, due to climate change, but climate change is always a mixed bag and some regions will fare better than others. Rich people will have an advantage in surviving, because they will continue to have better access to heat, clean water, ample food, good medical care, good communications, genetic manipulation, and so on. Human beings have already survived a couple of ice ages, and we're better equipped now to survive such a thing than we were in the past, when all we had were tools of stone and bone. We may have colonies on Mars in a hundred years, and after that who knows what the limits will be?

Answer 2

Global warming, the greenhouse affect created by man's own pollution. - oh what silly people live on this planet.

Naturally Global warming will mean the planet will heat up, causing water shortage, so dehydration and lack of food would possibly affect us.

I don't think the human race has a lot of intelligence really as they seem hell bent on self destruction.

However, I am not entirely convinced that the entire human race will become extinct, I do think there will always be some survivors, whether those survivors learn from previous mistakes made is another matter.

Answer 3

Extinctions are caused by catastrophic events.Things like lack of food, overcrowding, pollution, etc. will only reduce the population which will solve the problem. Even a full scale nuclear war is unlikely to kill everyone but it might. An large asteroid impact seems the most likely cause but the timing is unpredictable.

Answer 5

"Birth Control" and "Population" control will be implemented throughout the world. Governments will start putting a new male "Birth Control" supplements into the water supplies.

Then a selection process will allow health care providers and governments to decide which humans should have the reproduction rights. These will look at DNA endowments for criminal / addictive codes, genetics (eye color, intelligence), and family lineages. Societies will still favor selecting "Boys" when reproducing through the medical labs and some will illegally abort "Girls". This will lead to a socieity which will technologically advance further, until the ratio of men to women increases 5 to 1. This will cause war over the women, and all socieities will self-destruct.

Answer 6

You ignorant whiners, there are very few things that could truly make mankind extinct, and none of them are caused by man.

The short list is:

- an impact from a large meteor or comet or other celestial body
- a relatively nearby supernova
- a not-so-nearby gamma ray burst
- The sun expanding into its red giant phase (few billion years hence).

That's it. Plenty of people would survive anything else you can imagine.

Answer 7

In roughly 1,033 years.

If quasar theories are correct, a black hole is an accumulation of space debris that has become so heavy that the very atoms have collapsed upon themselves and in doing so expend an enourmous amount of energy.

But because of the phenominal gravitational forces, nothing leaves a black hole. Not even light. So we can't "prove" anything about them. Size, surface temperature, even time cannot be measured at or near a quasar (black hole). It's thought time itself is effected by gravity, and would slow down so much that it would take millions of years before you could reach the surface of the black hole. Unfortunately, anything 3-dimensional (like our bodies) would be destroyed by the effects of the gravitational forces of the quasar on our solar system's delicate orbital and rotational balance long before we got anywhere near its surface.

At the current rate at which the largest quasars are absorbing material from nearby galaxies, and the exponential nature of the progression, ours will enter the gravitational field of the nearest quasar in less than 1,033 years.

Answer 8

If mother nature doesn't finish us 1st via the melting of the polar ice caps. Man will probably finish himself via nuclear war it may even be an accident?When......Within the next (sorry to sound so pessimistic,) but the nuclear one i mentioned I'd give that 50 years at a push!!!

Answer 9

What is the point of asking Why? There won't be anyone left to analyse the answer - not even Yahoo!

Answer 10

Probably within 40-50 years. And you forgot our own stupidity in your factors.
