With the global population at more than 7 billion people and growing by the second, we thought we'd take another look at what the world could look like in the coming years.

Though most of us won't be around to see it, the United Nations has projected that our incredible population growth will level off at around 10 billion people by the year 2100.

Already, at 7 billion, we are experiencing severe poverty, hunger, a shortage of resources, increased urbanization and climate change issues.

Will we be doomed by 2100, or can we make it work? Since we've only got one planet (so far), let's hope for the latter.
