OUTSIDE: Is this book a sequel to The End of Poverty?
SACHS: Ending extreme poverty is like scaling a mountain. When you get to the top, you see that there's a chain of mountains behind that one. Common Wealth is a map to get us across.
How did we get to this point?
We're living in a unique era. We've done so well with our technological development that we have created the capacity to destroy the physical base of our society and imperil our survival. We should aim to stabilize the population, switch to sustainable-energy technologies, and negotiate new global agreements.
In the book, you list "travel" as something that individuals can do to help matters.
That came from my own experience. I'd been a professor in this field for 15 years, but I didn't understand just how extreme poverty and deprivation could be until I went to Africa and worked there.
Lonely Planet is the solution?
