Albers, quoted by Patricia Sloane (1989) in The visual nature of color, p. 1
“I would dare say that today this species is facing a very real and true danger of extinction, and no one can be sure, listen to this well, no one can be sure that it will survive this danger.”
University of Havana address (2005)
Context: I would dare say that today this species is facing a very real and true danger of extinction, and no one can be sure, listen to this well, no one can be sure that it will survive this danger.
Well, the fact that the species would not survive was discussed about 2,000 years ago. I remember that when I was a student I heard of the Apocalypse, a book of prophesy in the Bible. Apparently, 2000 years ago someone realized that this weak species could one day disappear.
