What would happen if every human being on Earth disappeared? This isn't the story of how we might vanish - it is the story of what happens to the world we leave behind. The second season of the fascinating History series "Life After People" takes a stunningly graphic journey to a world wiped clean of humanity. Using cinematic CGI these programmes reveal, in scientific detail, the fate of every aspect of the man-made world and how the landscape of our planet would change forever in our absence. From animal outbreaks and massive structural collapses to hordes of toxins and chemicals unleashed across the globe, we witness the final downfall of the most famous buildings in the world - The White House, Monticello and Versaille - and the destruction of man's most treasured antiquities and works of art, as the unforgiving power of nature is cruelly demonstrated. As the skies are darkened by swarms of locusts and the streets overrun with packs of wild dogs "Life After People: Series 2" reveals what happens in the hours, days, months and years after people disappear. Welcome to Earth, population zero.
