Quote examples
Frances Beinecke
American Activist
When the government undertakes or approves a major project such as a dam or highway project, it must make sure the project's impacts, environmental and otherwise, are considered. In many cases, NEPA gives the public its only opportunity to be heard about the project's impact on their community.

Quote examples
Jessye Norman
American Musician
I try to frighten my very young colleagues into studying and understanding their voices before they attempt things that are beyond them. It's wise to take gymnastics and swimming to strengthen the body, because people don't realise what an athletic undertaking singing actually is.

John Desmond Bernal
Irish Scientist

Quote examples
