“I don't think the human race will survive the next thousand years, unless we spread into space. There are too many accidents that can befall life on a single planet. But I'm an optimist. We will reach out to the stars”
"Colonies in space may be only hope, says Hawking" by Roger Highfield in Daily Telegraph (16 October 2001)

“The progressive world is necessarily divided into two classes — those who take the best of what there is and enjoy it — those who wish for something better and try to create it. Without these two classes the world would be badly off. They are the very conditions of progress, both the one and the other. Were there none who were discontented with what they have, the world would never reach anything better. ”
Cassandra (1860)
Jane Goodall
“My mission is to create a world where we can live in harmony with nature. ”
