On those pesky days when the world begins plunging into financial chaos and despair, it’s probably a good idea to try to remember we live on a REALLY big planet, and very little of it is made of money. As imaginary trillions turn into worthless pieces of paper, maybe some of those imaginary trillionaires will take a break from trying to horde the remnants of their empires, and take a look around. French photographer Yann Arthus-Bertrand has been looking around the world since 1994. In an attempt to inspire people to think globally about sustainable living, he has taken astoundingly beautiful photographs from the air in over 150 countries. These are not simply nature photographs; often the subjects are the sad results of industry, technology, or war. Who would think, for instance, that the waste produced by a copper mine could be beautiful? Referring to the resulting collection of images, Arthus-Bertrand suggests: “Though it invites us all to take our own responsibilities, this testimony remains resolutely optimistic. Each portrait, be it of the Earth or its inhabitants, aims at showing the best in order to appeal to what is best in us. For the will to protect is indeed strongest towards that which one has learnt to understand and love.” Which I guess will be a bit of a problem for those who have primarily “learnt to understand and love” their wealth.
