Science Quotes by Helen Caldicott (1 quote)
Trees are more than just havens for animals, birds, insects, and humans; they are also the lungs of the earth. Just as we breathe oxygen into our lungs and exhale carbon dioxide, so trees breathe carbon dioxide into their leaves and exhale oxygen.
— Helen Caldicott
In If You Love This Planet: A Plan to Save the Earth (1992, 2009), 51.

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) --
