People is already saying that some day, humans will be able to live in Mars or other planets.
Some people even think humans will even visit other Galaxies. But I disagree with that for several reasons.
The first and most important is that we will not last forever. No species can avoid extinction.
Scientists think that most species (not all of them, but most), have a lifespan of about one million years. After that time, the entire species dissapears or becomes into another species, a more evolved one.
Until recently, scientists believed that humans were a much younger species, with only about 30,000 years in Earth.
Now we know that humans have been in Earth about a million years. New human fossil remains have confirmed this. So, we are already OLD as a species.
We will probably last a little more than other species because of the technology, and medical advances and things like that, but the reality is that our time is coming.
So, the question is, how will extinction hit humans?
I think it will be the climate change. Lots of species were killed by climate change 10.000 years ago, including the Irish Elk, the Mammoth and probably even the Neanderthal Man. So, it could easily kill us.
A new Ice Age would kill the entire population of the northern countries, and even if people escapes to the south, the glaciation will cause giant storms, that would also alterate the climate in the Southern Hemisphere and probably kill millions of humans.
Probably, the very last humans will die of flu... Anyway, the truth is that humans will become extinct.
But how exactly? And what animals will take over the world then?
Im interested in your opinions!
