Everyday Use Quotes (1 quote)
As we consider the manifold materials that keep us going between breakfast and bedtime, our welfare is served by the wild species that make up the planetary ecosystem with us. To date, scientists have conducted intensive screening of less than 1 percent of all species with a view to determining their economic potential. Yet these preliminary investigations have thrown up thousands of products of everyday use.
A Wealth Of Wild Species: Storehouse For Human Welfare (1983), Prologue, 8.
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) --
