I am a great admirer of the men who went to the moon and all the engineers and scientists that made it possible. But I am really glad that President Obama has cancelled the current plan to return to the moon. Such an adventure would be truly pointless. Those who say this would be the first step on a journey to the stars and similar nonsense have not done their sums. Either on the survivability of space flight or the cost of the endeavour.
Without meaning to sound too hippy-ish, the fact is that human beings can only exist only on Earth. We exist as a species and a community and we need the food that only grows on Earth. We simply cannot live as isolated individuals. The sooner we focus our full attention on the Earth the better. The moon will still be there we have solved our problems here on Earth.
