"An unpolluted night sky that allows the enjoyment and contemplation of the firmament should be considered an inalienable right of humankind equivalent to all other environmental, social, and cultural rights, due to its impact on the development of all peoples and on the conservation of biodiversity."
Starlight Declaration. La Palma, Spain 2008.

"The sky, our common and universal heritage, is an integral part of the environment perceived by humanity.

This interest in astronomy has had profound implications for science, philosophy, religion, culture and our general conception of the universe".
