Happy Earth Day 2018

Happy Earth Day 2018!

“In our obscurity, in all this vastness,
there is no hint that help will come from elsewhere
to save us from ourselves.
The Earth is the onl world known so far to harbor life.

There is no where else, at least in the near future,
to which our species could migrate. Visit, yes. Settle, not yet.

Like it or not, for the moment,
the Earth is where we make our stand.

It has been said that astronomy is humbling, and
character-building experience. There is perhaps no better demonstration of the
folly of human conceits than this distant image.

To me, it underscores our responsibility to deal more
kindly with one another and to preserve and cherish
the pale blue dot, the only home we’ve ever known.”

– Carl Sagan

“I want to know my ancestors–all of them.
I want to be a good, strong link in the chain of generations.
I want to protect my children and the children
of ages to come.
We, who embody the local eyes and ears and thoughts and feelings of the cosmos,
we’ve begun to learn the story of our origins–star stuff
contemplating the evolution of matter, tracing that long path by which it arrived
at consciousness.
We and the other living things on this planet carry a legacy of cosmic evolution
spanning billions of years.
If we take that knowledge to heart,
if we come to know and love nature as it really is,
then we will surely be remembered by our descendents as good,
strong links in the chain of life.
And our children will continue this sacred searching,
seeing for us as we have seen for those who came before,
discovering wonders yet undreamt of…in the cosmos.”
– Neil DeGrasse-Tyson
