250 million years, long before dinosaurs roamed the earth, the earth and the oceans teemed with life. This was the Permian, a golden era of biodiversity that was about to come crashing to an end. Within a few thousand years, 95% of life on the planet would be destroyed, Earth’s biggest mass extinction has ever known. What natural disaster could kill such a massive scale? Only in recent years the test has begun to emerge from the rocks in Antarctica, Siberia and Greenland.

The disappearance of the dinosaurs 65 million years (so called K / T boundary), it was nothing compared to the Permian mass extinction. The K / T event ended with 60% of life on Earth, the Permian event 95%. The geological data to explain the destruction have been hard to find, simply because the rocks are very old and therefore subject to all kinds of erosion processes.

It seems plausible that some kind of catastrophic environmental changes have made life unbearable in vast regions of the planet.
In the 1990s, the search for evidence was directed to a region known as the Siberian Traps. Today is a sub-Arctic wilderness, but 250 million years, more than 200,000 km ² of a stream of molten lava. The Siberian Traps are experiencing a “flood basalt eruption,” the largest volcanic effect on Earth. Instead of lava spewing volcanoes isolated division of the cortex and the curtains of lava were released. And the eruption of Siberian flood lasted for millions of years. Could the volcanic activity on such a long period alter the climate enough to kill 95% of life on Earth?

  1. The Bible commands us to be students(disciples) and has been the most scrutinized collection of writings on earth, ever!A wise man hears both sides issue BEFORE he decides the issueThere are 2 basic reasons for people not searching out THE TRUTH1. Propaganda, be it religious,scientific,pop culture,folk law etc2. Being unwilling to accept that they are created…. because to acknowledge this, would mean that there is a God; and that He requires us to OBEY Him.You’ll reap what you sow!

  2. If You acknowledge our Creator, turn away from sin and make Jesus Christ your Lord, then you shall obtain everlasting life full of fun in his Kingdom.Else wise you can be destroyed in the lake of fire for your unrepentant ingratitude for this amazing life He gave you.The choice my friend is entirely up to you!

  3. Methane hydrate gas bubbling up the surface and nobody ever though of creating a kind of flexible umbrella like structure connected to a pipe leading up to the surface where it can be stored and used? When opportunity knocks at the door, then welcome it!

  5. If that happened in the past then it can happen again. Thus the need to explore space and the solar system and colonize space and all the planets so that if anything happens on Earth then the rest of mankind and his civilization will live on. Eric Laithwaite discovered a form of mechanical antigravity machine and that can be useful for an all out exploration and colonization of the entire Solar System!

  6. So let us get this right you think that the tyrants who were responsible for the deaths/slaughter of104.3 million people are amazing compared to people who believe in our creator?You should stop and think about the real misery those people went through, and be ashamed of yourself.Have you no regard for the well being of your fellow man?

  7. The BBC spreads disinformation/lies in an endeavor to control the minds of men so that they will not know or perceive the truth. And being deceived they shall be destroyedThe Bible declares the truth so that men may control their own minds and get to know the reality of their creator WYWH and obtain salvation through his son Y’shua (Jesus) and subsequently become heirs to everlasting life.We are engaged in the battle of our lives (literally) the battle for the truth!BBC spreads fiction

  9. More BBC mind control programing…..It was called Noah’s flood 98% of earths cultures remember it, and have passed it down in their folk law.”If you tell a lie big enough and keep repeating it, people will eventually come to believe it.The lie can be maintained only for such time as the State can shield the people from the political, economic and/or military consequences of the lie……” Joseph GoebbelsIf you don’t acknowledge God you wont acknowledge that denying Jesus Has Consequences

  10. No, not all religious people are stupid. May be hard for you to believe I know, given the state of America, but believe it or not I have met some very intelligent religious people in my life. I think however it is safe to say that all religious fundamentalists are stupid – the more intelligent a religious person is the more they tend to be liberal. (That is a trend I have observed). And actually all of Isaac Newtons scientific ambitions were directed toward better understanding God.

    I love the hive-mind mentality of some of the geologists. “Asteroids did it, a really big one, the size of MANHATTAN! Oy Vey! Wait, no crater? Errrr, well I have a pretty graphic on my laptop that shows how lava fills it in! Lack of iridium? Errr, well (crickets chirping) Oh, I have crystals in Antarctica (I always wanted to go there, here’s my chance! Grant money please.) that show shearing. Must have been caused by that asteroid. I swear, science has devolved into this.

  12. richeybee says:

    “life finds a way” i’m sure that was out of a film. Sure enough the process will continue and probably a lot quicker than it did in the early earth. It happened once before with the mammals when they inherited the earth after the dinosaurs became extinct.

  13. richeybee says:

    ok Religious people are stupid, Isaac Newton was around 350 years ago when it was rational to be religious because science had not proven what it has today (i.s before Charles Darwin etc) so its understandable he was religious. Tell me anything significant he did with his religion?

  14. matbbm says:

    yer where so retarded because we research all the evidence of this world. and we base are beliefs on what we see. and not some fairytale book about some magic man who walked on water, whiten thousands of years ago to control the people with fear about hell.

  15. richeybee says:

    Just because your religion gives your life meaning and it comforts you doesn’t mean it is true. Atheists find other ways to fulfill there lives. The argument that we need a celestial law giver in order for us to be moral is plainly wrong.

  16. Ddroyd1 says:

    I feel sorry for you who do not believe in God. Without God, life has no point. It is easy to be an atheist when all is going well. To not live for God is to live for the self. Our society is taught to be working competitive consumers for the self. No wonder so many people are miserable. To live for God means to live for others; a life based on joy and giving. To not to live for God is to live for yourself; by your own rules. This is a life of selfishness, misery and fear.

  17. So volcanoes in Siberia killed almost all life on earth. Really? Really really?I’d like more evidence on how it happened, and why certain species survived. I get the feeling we’re not even close to understanding what happened.

  18. rjrjo grapes says:

    So what does that statement make you? Please explane your self because I would really like to know why a person would say something like that to categorize anyone who would believe in any type of a religion. Don’t get me wrong. I would just like to try to understand what you mean behind what you believe. Peace

  19. I think the take-away from this video is that the forms of life that develop on Earth are vulnerable to the natural forces. Species come and species go. That’s cold comfort in itself. Yet, we often like to believe that the process of life on this planet is virtually indestructible. Venus, Earth’s Twin, tells a different story. The speed of our spin is shielding us from the Sun’s UV and ET objects. But Earth is cooling, spinning slower, losing gravity. It too will die, along with our sun.

  20. BHALT0S says:

    I doubt the earth nearly died, think about it, the earth was devoid of life in the beginning, so life came to be here one way or another because the conditions here on earth were good for life to begin and evolve etc. so even if were wiped out again, then the same thing will happen all over again, remeber the earth is what four and a half billion years old, if that was crammed into one year for perspective, humans have been around since the last few mins of december 31st.
