Answer 2

If population levels continue to rise at the current rate, our grandchildren will see the Earth plunged into an unprecedented environmental crisis, argues computational scientist Stephen Emmott in this extract from his book Ten Billion.

Earth is home to millions of species. Just one dominates it. Us. Our cleverness, our inventiveness and our activities have modified almost every part of our planet. In fact, we are having a profound impact on it. Indeed, our cleverness, our inventiveness and our activities are now the drivers of every global problem we face. And every one of these problems is accelerating as we continue to grow towards a global population of 10 billion. In fact, I believe we can rightly call the situation we're in right now an emergency – an unprecedented planetary emergency.
