Earth
Earth is the third planet from the Sun and the only object in the Universe known to harbor life. According to radiometric dating and other sources of evidence, Earth formed over 4.5 billion years ago. Earth's gravity interacts with other objects in space, especially the Sun and the Moon, Earth's only natural satellite. Earth revolves around the Sun in 365.26 days, a period known as an Earth year. During this time, Earth rotates about its axis about 366.26 times.
Earth
We travel together, passengers on a little space ship, dependent on its vulnerable reserves of air and soil; all committed for our safety to its security and peace; preserved from annihilation only by the care, the work, and, I will say, the love we give our fragile craft. We cannot maintain it half fortunate, half miserable, half confident, half despairing, half slave—to the ancient enemies of man—half free in a liberation of resources undreamed of until this day. No craft, no crew can travel safely with such vast contradictions. On their resolution depends the survival of us all.
Adlai Stevenson, U.S. ambassador to the United Nations, last major speech, to the Economic and Social Council of the United Nations, Geneva, Switzerland (July 9, 1965); in Albert Roland, Richard Wilson, and Michael Rahill, eds., Adlai Stevenson of the United Nations (1965), p. 224.
Earth
This poor world, the object of so much insane attachment, we are about to leave; it is but misery, vanity, and folly; a phantom, — the very fashion of which "passeth away."
François Fénelon, reported in Josiah Hotchkiss Gilbert, Dictionary of Burning Words of Brilliant Writers (1895), p. 206.
Earth
But the meek shall inherit the earth; and shall delight themselves in the abundance of peace.
David, Book of Psalms 37:11.
Aside from being a public health hazard, particles in the atmosphere affect climate. New data mining and analysis methods are shedding light on the role of one of the most important components, black carbon.
