If you have ever wondered why have come of earth creations have decreased in size, then this video is for you. Peter Ward gives a detailed explanation about the mass extinctions that have occurred on earth over the past years and what has caused them.
Peter goes on to discuss how he believes and has testified that the culprit to this mass extinction is in fact a poison called hydrogen sulfide which can/may have an interesting application in medicine. He talks about how the past, different planets and how things have changed over the past centuries from the beginning of time to this very day.
I did enjoy this TED talk because it informs people on what is actually occurring in the world today. It gives us any other look on things we never knew existed, never knew how they functioned or why these things happen. I will admit this segment is rather long but the reality is it does give us rather good information which I think should inspire people to watch it.
In my opinion is segment is rather informative and truly inspiring and I encourage everyone to view this TED talk on Earth’s Mass Extinctions.
