Carl Edward Sagan (9 November 1934 – 20 December 1996) was an American astronomer, planetary scientist, cosmologist, astrophysicist, astrobiologist, author, and science communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the hypothesis, accepted since, that the high surface temperatures of Venus can be attributed to, and calculated using, the greenhouse effect. He testified to the US Congress in 1985 that the greenhouse effect will change the earth's climate system.

En el polo opuesto de la discusión, la frase -derecho a la vida- constituye un ejemplo claro de expresión altisonante concebida para impresionar más que para aclarar las cosas. Ni hoy ni nunca ha existido en ningún país de la tierra el derecho a la vida. Criamos animales domésticos para luego darles muerte, destruimos los bosques, contaminamos ríos y lagos hasta causar la muerte de toda la fauna piscícola, cazamos venados por deporte, leopardos por la piel y ballenas para preparar comida para los perros, atrapamos a los delfines, boqueantes y semiasfixiados, con grandes redes del tipo utilizado para la pesca del atún, y senteciamos a muerte a los perros cachorros para -equilibrar la población-. Todos estos animales y vegetales están tan vivos como nosotros. Lo que muchas sociedades humanas protegen no es la vida, sino la vida el hombre, y aún así desencadenamos guerras con medios -modernos- que causan estragos a la población civil y que suponen un tributo tan escandaloso que muchos de nosotros ni siquiera nos atrevemos a entrar en su consideración.
In those cultures lacking unfamiliar challenges, external or internal, where fundamental change is unneeded, novel ideas need not be encouraged. Indeed, heresies can be declared dangerous; thinking can be rigidified; and sanctions against impermissible ideas can be enforced — all without much harm. But under varied and changing environmental or biological circumstances, simply copying the old ways no longer works. Then, a premium awaits those who, instead of blandly following tradition, or trying to foist their preferences on to the physical or social Universe, are open to what the Universe teaches.
