Famous quotes containing the word plants:
“When the
Marne flowed by the plants nodded
And above the glistering Gila
A sunset as beautiful as the Athabasca
Stammered. The Zambezi chimed. The Oxus
Flowed somewhere.”
—John Ashbery (b. 1927)
“Probably if our lives were more conformed to nature, we should not need to defend ourselves against her heats and colds, but find her our constant nurse and friend, as do plants and quadrupeds.”
—Henry David Thoreau (1817–1862)
“... feminism is a political term and it must be recognized as such: it is political in women’s terms. What are these terms? Essentially it means making connections: between personal power and economic power, between domestic oppression and labor exploitation, between plants and chemicals, feelings and theories; it means making connections between our inside worlds and the outside world.”
—Anica Vesel Mander, U.S. author and feminist, and Anne Kent Rush (b. 1945)
