Why Did Brit Crown Knight Elton John and Not James Lovelock?

It may be a reflection on the times that the British Crown choose to select a rock and roll musician famous for homosexuality and ignore the inventor of the Gaia Theory of ecospheric self-regulation. James Lovelock also proved the existence of the ozone hole at Antarctica. Isn't the survival of human life on Earth at least as important as homosexual celebrations in London and elsewhere?
