Unsustainability Quotes (1 quote)
If there were a billion people living on the planet, we could do whatever we please. But there are nearly seven billion. At this scale, life as we know it today is not sustainable.
As told to and quoted in Jeff Goodell, How to Cool the Planet: Geoengineering and the Audacious Quest to Fix Earth’s Climate (2010), 91.
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) --
