This is quite an interesting article showing images of how the world would look if human life ceased to exist. This picture shows how parts of London would rot and how flood waters would enter the city, as without power to the Thames Barrier central London would be mostly underwater. Other pictures show impressions of how Buckingham Palace and Tower Bridge would decay. The pictures are based on both scientific expertise and an understanding of history to predict what would happen. Within a few weeks the planet would be plunged into darkness and within six months areas would start to be repopulated by animals including domestic pets. Within 40 to 50 years modern buildings would start to collapse and within 100 years cars would have rotted away. The more aggressive predators would become dominant with livestock being mainly wiped out. What a cheerful article.
