We can't equate democracy with Christianity because the largest democracy on earth is India, which is primarily Hindu. The third largest democracy is Indonesia, which is Islamic. Democracy and freedom are not dependent on Christian beliefs.
The first glimpse that we have of the notions which the Greeks possessed of the shape and the inhabitants of the earth is afforded by the poems passing under the name of Homer.
The obvious issue is providing clean drinking water and sanitation to every single human being on earth at the cost of little more than one year of the Kyoto treaty.
The end of all things is at hand; that Satan's kingdom will be destroyed, and Satan chained down for a thousand years, and Christ's kingdom established upon earth.
In the Andes and the Alps, I have seen melting glaciers. At both of the Earth's Poles, I have seen open sea where ice once dominated the horizon.
In the middle of my third Hollywood picture The Magician, the earthquake hit Hollywood. Not the real earthquake. Just the talkies.
The atom bombs are piling up in the factories, the police are prowling through the cities, the lies are streaming from the loudspeakers, but the earth is still going round the sun.

I know being pregnant and giving birth is the most wonderful thing on Earth. I know that after you have a baby, there is a sense of addiction, a need to have another. It's biological.
The G8 nations, together with the five major emerging economies of China, India, South Africa, Brazil, Mexico, use almost three-quarters of the Earth's biocapacity - the capacity of the world's ecosystems to produce natural resources and to reduce harmful substances.

The one thing all humans share is that we all inhabit the same limited amount of real estate, which is Planet Earth.
Five centuries from now - barring unimaginable catastrophe - the moon will be developed real estate. There's economic incentive to exploit the moon - the helium-3 will be useful in powering fusion reactors, and the rare earth elements could supplant the limited terrestrial supply of these materials.
A billion could live off the earth; 6 billion living as we do is far too many, and you run out of planet in no time.
