One of them is just the way in which our population keeps going up. We are I think, past the point where the earth can support us all comfortably, and we're still going up. That's one thing. Second thing, is the way in which we are constantly wasting our time, our money, our efforts, our energy, our emotions, on 19th century attitudes, in which we somehow think that one little glob of the earth is the only important glob and that as long as it somehow gains, it doesn't matter that everybody else loses. This is ridiculous, and it's no longer so.
Nobody can gain if everyone else loses.
In short, we're still playing with nationalism, when it's no longer suitable, when it's an insane attitude. And number 3 is of course that as an offshoot of nationalism we're wasting all our resources on preparations for a war we can't fight without suicide. We've got to understand the danger we face, and we've got to make up our mind that nothing is more important than co-operation, that all the life and death problems we face are global problems, must have global solutions and whether we like it or not, we must act together because if we don't we're all down the drain, with exception. And if we do get together we have to have some project which is going to occupy our minds and give us a sensation of pride and accomplishment. And the only thing that's really large enough is to conquer space, really, to build solar power collecting stations in space, to build our nuclear power stations in space where if something does happen to one of them, it doesn't instantly affect large population centres.
