When I read the Club of Rome’s 'Limits to Growth' report in 1973, I concluded that if their numbers were reasonably correct, we would see around 2030 increasingly fierce competition for increasingly scarce resources, especially oil. That is what we are seeing now, I think.

A statement from the family of Apollo astronaut Jim Lovell on his passing: "We are saddened to announce the passing of our beloved father, USN Captain James A. "Jim" Lovell, a Navy pilot and officer, astronaut, leader, and space explorer. He was 97. We are enormously proud of his amazing life and career accomplishments, highlighted by his legendary leadership in pioneering human space flight. But, to all of us, he was Dad, Granddad, and the Leader of our family. Most importantly, he was our Hero. We will miss his unshakeable optimism, his sense of humor, and the way he made each of us feel we could do the impossible. He was truly one of a kind."
