Norman Borlaug on receiving the Nobel Prize for the green revolution, said it well:
"The green revolution has won a temporary success in man's war against hunger and deprivation; it has given man a breathing space. If fully implemented, the revolution can provide sufficient food for sustenance during the next three decades. But the frightening power of human reproduction must also be curbed; otherwise the success of the green revolution will be ephemeral only.
Most people still fail to comprehend the magnitude and menace of the "Population Monster"...Since man is potentially a rational being, however, I am confident that within the next two decades he will recognize the self-destructive course he steers along the road of irresponsible population growth..."
We haven't steered away from that course. Fusion would accelerate us on it. If we have to come into balance at some point, why not now instead of when we exhaust fusion's potential? Why does this community think we can solve every technical problem from the moon to Mars to fusion, but we can't live in balance with nature?
