"There was a time when it appeared that science would solve all of humanity's problems. Today, we've discovered that that's not the case.

Saving the species will be a titanic undertaking, but it will never be possible through economic and social systems in which the only things that count are profit and advertising." - Fidel Castro.
“The thirst for profit without limits of the capitalist system is destroying the planet. Under capitalism, we are not human beings, but consumers. Under capitalism, Mother Earth does not exist. Instead, there are raw materials.” - Morales.
"Progress to those who see the light. Charity to those who tremble at its rays." - Marti.
