The malaria parasite has been killing children and sapping the strength of whole populations for tens of thousands of years. It is impossible to calculate the harm malaria has done to the world.

When you think about the scale of human populations all over the world and the fact that there's so much here, really, the only way to be able to visualize that is to pull back in space... It allows us to see hidden temples and tombs and pyramids and even entire settlements.

One of the things that is wonderful about hymns is that they are a sort of universally shared poetry, at least among certain populations.

When you look at the fittest, leanest populations like Japan and Scandinavia, they don't even go to the gym. The average person in Sydney takes 11,000 steps a day, and the average person in Houston does 4000. Guess who is going to be leaner, regardless of their diet?

If we can reach populations in developing countries and help them understand the value of their indigenous diet and lifestyles rather than copying ours, perhaps we can reverse the exponential rise in cardiovascular disease that is plaguing them.

The fact is not kill entire populations is able to infect entire regions of land and control the only cure.

Appreciate the power of rumor often malicious no matter how preposterous within the local populations you are seeking to help.

Many African leaders refuse to send their troops on peace keeping missions abroad because they probably need their armies to intimidate their own populations.

A majority perhaps as many as 75 percent of abortion clinics are in areas with high minority populations. Abortion apologists will say this is because they want to serve the poor. You don't serve the poor however by taking their money to terminate their children.

It is extraordinary that whole populations have no projects for the future none at all. It certainly is extraordinary but it is certainly true.
