I don’t want to be pessimist but last night I saw a video about how the world could end, and it’s not a simple video from a non-professional person, it was recorded by a scientist.

The scientist tells eight ways of how our dear planet and life on it could be disappear, and if you watch it, you will see that our home is in fact very fragile. I’m going to try to relate them, we are responsible of our pretty house and the existence of human beings.

One way it could be by a mortal virus, I’m sure you have heard about Ebola, H1N1 and the black pest that killed most of European people some centuries ago. Today it's really easy for a virus to expand all over the world, due to globalization, goods and people move everyday among all countries. Other one, and maybe even funny, we are going to be conquer by our own creations, as you know, the advances of AI (artificial intelligence) and technology each year replace us in all fields, services, manufacturing, bank… The place for humans is shrinking and it looks that this is an irreversible process. Other one comes from the king of our Milky way, the sun irradiates sometimes big waves of their energy which are extremely dangerous, it’s like a meteorite will hit us. And talking about meteorites, this is another way, as you know in the past, one of this was responsible of the extinction of dinosaurs, and of course, we could detect them but sometimes it happen when it’s too late.

The one that got scared to me most it’s a nuclear war. The power of this bombs it’s almost unimaginable, just with one of them side effects will reach the entire planet, and some countries have hundreds of them. I thought that this could happen due to the bad character and stupidity of governments and presidents, and I said to myself, well I live in South America and it’s very unlikely that one bomb of these fall here, as far as I know, none country of South America have one, so we are secure. Well I didn’t know about the power of those devil’s artefacts, no matter if the bomb explode in North Korea (which wanted to start a war with America according to the news); what happens next is that a huge layer of toxic gas will covered the skies (as clouds cover sky usually) from every country, we will stay in darkness for years and without the sun, we won’t be able of producing food and we will die from starvation.

There are other ways more, but I reached the capacity for the article. So what do you think?
