End of Time? Planet Earth without species 'homo sapiens'?
I can imagine an Earth without our species on it. But it won't be true in reality for the next 5 billion years. (After that our Sun will turn into a Red Giant and life on Earth will be impossible.) I am very optimistic about our survival. Who can beat us - unless we kill ourselves? The species that is able to invent 'Mäusenplatten' (Miischplatta, Plaana or Stadelbeine) or 'Staddle stones'. Stones that keep mouses, rats and other vermin out of the food stocks.
