What if tomorrow the human race dissapeared? Whether by virus, metor or rapture, what if we just vanished. The book The World Without Us addresses it. How long would it take for our planet to heal the scars that we have inflicted on it. It address the plastic issue, nuclear waste as well as several other topics. How long would the world that we have built take to waste away and remerdge as the Garden of Eden?
I recommend this book, even if you are not remotely interested in the green movement. It gives you an unbiased look at the world and how we are treating it.
