Think environmental change happens too slowly to matter to your lifetime? “Your Life on Earth,” an intriguing  interactive developed by the BBC, just might get you thinking otherwise. Enter your birth date, gender and height, and up pops a personalized infographic showing how much you and the world around you have changed and are expected to continue to change in your lifetime, from how much sea level has risen since you were born to how old you’ll be when oil, coal and natural gas supplies are projected to dry up. Give it a try and gain a whole new respect for how quickly conditions can become worse — or, if we so choose, improve. View Ensia homepage
