Pale Blue Dot: A Vision of the Human Future in Space

Carl Sagan

The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot.

Due to our own actions or inactions, and the misuse of our technology, we live at an extraordinary moment, for the Earth at least - the first time that a species has become able to wipe itself out. But this is also, we may note, the first time that a species has become able to journey to the planets and the stars.

BUMMER was originally sold as a barter deal. 'Let us spy on you and in return you'll get free services.' This might seem like a reasonable deal in the short term, but in the long term it's terrible.

The Uninhabitable Earth: Life After Warming

The Uninhabitable Earth: Life After Warming David Wallace-Wells If the world's most conspicuous emitters, the top 10 percent, reduced their emissions to only the EU average, total global emissions would fall by 35 percent.
