Dr Peter Ward, Univ of Washington, Life's Rivers in Time
Ғылым және технология
Several times in the distant past, catastrophic extinctions have swept the Earth, causing more than half of all species -from single-celled organisms to awe-inspiring behemoths -to suddenly vanish and be replaced by new life forms. Today the rich diversity of life on the Earth is again in grave danger -and the cause is not a sudden cataclysmic event but rather humankind´s devastation of the environment.

Love Peter Ward's books, have almost all of them. One of my hero's. Thanks for sharing this presentation!
Have RARE EARTH, UNDER A GREEN SKY, and OUT OF THIN AIR. We love our geology teachers!
It's annoying his videos generally get so few views relative to the mindless nonsense on social media. Thanks for taking the time Dr Ward.
... as a German Biologist - Peter Ward is a highly impressive Biologist and Role Model for the World. As the World has no respect for Persons like Ward we self extinct easy...
Peter Ward is awesome.
