Who will speak for Planet Earth?

It's sometimes easier to reject strong evidence than to admit that we've been wrong, this is information about ourselves worth having.

Ours is the first generation that has grown up with science-fiction ideas.

Across the sea of space, the stars are other suns.

If the greenhouse effect is a blanket in which we wrap ourselves to keep warm, nuclear winter kicks the blanket off.

The total number of stars in the Universe is larger than all the grains of sand on all the beaches of the planet Earth.

In the way that scepticism is sometimes applied to issues of public concern, there is a tendency to belittle, to condescend, to ignore the fact that, deluded or not, supporters of superstition and pseudoscience are human beings with real feelings, who, like the sceptics, are trying to figure out how the world works and what our role in it might be. Their motives are in many cases consonant with science. If their culture has not given them all the tools they need to pursue this great quest, let us temper our criticism with kindness. None of us comes fully equipped.
