Origins: How Earth's History Shaped Human History by Lewis Dartnell

I picked this one out of curiosity. And, yes it was a good pick.

This talks about how Earth's evolution over a billion years shaped the existence of life (human life) on the planet. How over the years the Earth went through various transformations creating the things/elements which will eventually support the human sustenance. Of course, humans were responsible to identify the use of each of these elements and exploit it.

One thing which is also a central point is that cooling comes more naturally to Earth as compared to heat. Human activities in the last 200 years (largely after the industrial revolution) has been responsible for the heating of Earth (global warming) disproportionately. But cool is more natural (that's why the Ice Ages, and yes that is plural) so one fine day its going to be unbearably cold but not in a lifetime.

Larger point is that human life has always been looked down upon as a speck at the astronomical levels. And that's more than true. Even after all the scientific developments the existence of life as we know can be wiped in a moment, and the cycle of life starts again from null.

So, next time you're worried about something than think about it at a tectonic level :)

Peace
