      That’s almost impossible to predict!

      I think one thing we can be sure of is there’d be more forests. Humans have cleared so much of it away for things like agriculture, settlements and even just to use the wood. Rivers, lakes and seas would be much cleaner.

      This is, of course, provided nothing else evolved in a similar way to humans in the absence of us…

      Less CO2 in the atmosphere. Less pollution.
      Cleaner and generally nicer, I’d imagine.

      It would all probably be a lot cleaner and a lot more overgrown. How exactly it would have all panned out is impossible to tell. Another species would probably pop up as the dominant species and who knows what they would do with the world.
