We have big, big problems - flooding, earthquake, and many foolish things which now people are doing - I mean, these self-made catastrophes. We are able to give to every man on the street the possibilities to help himself. And to fight for this was one of my duties.
My daughter is one of my greatest inspirations. She's an environmentalist, she plays piano, she's raising money for the earthquake victims in Nepal. Every day she surprises me and teaches me something.
I live a half mile from the San Andreas fault - a fact that bubbles up into my consciousness every time some other part of the world experiences an earthquake. I sometimes wonder whether this subterranean sense of impending disaster is at least partly responsible for Silicon Valley's feverish, get-it-done-yesterday work norms.
Even before the earthquake in Haiti, only half the country's population had a source of safe drinking water.
I am grateful to President George W. Bush for PEPFAR, which is saving the lives of millions of people in poor countries and to both Presidents Bush for the work we've done together after the South Asia tsunami, Hurricane Katrina and the Haitian earthquake.
Haiti is always talking about decentralization and nothing has been so obvious, perhaps a weakness, as the centralized nature of Haitian society as being revealed by the earthquake. I mean, they lost all these medical training programs because they didn't have them anywhere else.
Photographer James Nachtwey has spent his professional life in the places people most want to avoid: war zones and refugee camps, the city flattened by an earthquake, the village swallowed by a flood, the farm hollowed out by famine.
There's been a lot of really great intensive research into earthquakes, but we can't predict an earthquake down to the day. We can't predict where a hurricane is going to be a month in advance.
Shortly after the 2004 Indonesian earthquake, I read that the earthquake had affected the rotation of the earth, shortening the length of our 24-hour day. Even though the change was extremely slight - only a few microseconds - I found the idea incredibly haunting.
I got quite annoyed after the Haiti earthquake. A baby was taken from the wreckage and people said it was a miracle. It would have been a miracle had God stopped the earthquake. More wonderful was that a load of evolved monkeys got together to save the life of a child that wasn't theirs.
Haiti is not an easy place to fight disease, even in the best of times. That was true even before a devastating earthquake ravaged Haiti's capital and largest city, Port-au-Prince, in 2010.
I will remember this day for the rest of my life. There is nothing you can say. It's just like you won the match after the earthquake and it just feels great.
