• Agriculture represents the single most profound ecological change in the entire 3.5 billion-year history of life.

  • Indeed, to develop agriculture is essentially to declare war on ecosystems — converting land to produce one or two food crops, with all other native plant species all now classified as unwanted 'weeds' — and all but a few domesticated species of animals now considered as pests.
    • Niles Eldredge, "The Sixth Extinction", 2001

  • There is little doubt left in the minds of professional biologists that Earth is currently faced with a mounting loss of species that threatens to rival the five great mass extinctions of the geological past.
    • Niles Eldredge, "The Sixth Extinction", 2001

  • This explosion of human population, especially in the post-Industrial Revolution years of the past two centuries, coupled with the unequal distribution and consumption of wealth on the planet, is the underlying cause of the Sixth Extinction.

  • The most unhappy thing about conservation is that it is never permanent. If we save a priceless woodland today, it is threatened from another quarter tomorrow.
    • Marjory Stoneman Douglas (1890-1998), quoted in Facing Florida's Environmental Future, April 1990.

  • The conservationist's most Important task, if we are to save the earth, is to educate.
    • Peter Scott, founder chairman of the World Wildlife Federation, quoted in the Sunday Telegraph, November 6, 1986.

  • Civilization began around wetlands; today's civilization has every reason to leave them wet and wild.
    • Edward Maltby, Waterlogged Wealth, 1986.

  • By 2050, at bio-extinction's current rate, between 25 per cent and 50 per cent of all species will have disappeared or be too few in numbers to survive. There'll be a few over-visited parks, the coral reefs will be beaten up, grasslands overgrazed. Vast areas of the tropics that have lost their forests will have the same damn weeds, bushes and scrawny eucalyptus trees so that you don't know if you're in Africa or the Americas.

  • More than a billion women around the world want to emulate western women’s lifestyles and are rapidly acquiring the material ability to do so. It is therefore vital that in our leadership we display some reserve and responsibility in our spending so that the world’s finite resources will be available for our children, their children and their children’s children.
    • Louise Burfitt-Dons, Speech on Hot Women Campaign given at UK Aware circa 2008.


  • The prosperity we have known up to the present is the consequence of rapidly spending the planet's irreplaceable capital.
    • Aldous Huxley

  • Study nature, love nature, stay close to nature. It will never fail you.
    • Frank Lloyd Wright

  • I believe in God, only I spell it 'Nature'.
    • Frank Lloyd Wright

  • You know, the basic problem is greed and poverty. The poor chop down trees because they need wood for fire, and big companies chop them down for profit, with corrupt officials getting their take while looking the other way, before the wood is exported or sold to local factories. No one thinks about the wildlife that is being left homeless or destroyed due to this desperation and this greed.
    • Steve Irwin

  • It's no good being a conservationist and keeping your lips sealed tight, no matter what you might be doing physically. You've got to tell people what you're doing, so they'll pick it up too, do the same thing. As for me, I'm going to keep on doing this until I can't do it anymore, and that will be the day when I say goodbye to this world.
    • Steve Irwin

  • I believe sustainable use is the greatest propaganda in wildlife conservation at the moment.
    • Steve Irwin

  • The real cure for our environmental problems is to understand that our job is to salvage Mother Nature ... We are facing a formidable enemy in this field. It is the hunters ... and to convince them to leave their guns on the wall is going to be very difficult.
    • Jacques-Yves Cousteau

  • Our attitude towards plants is a singularly narrow one. If we see any immediate utility in a plant we foster it. If for any reason we find its presence undesirable or merely a matter of indifference, we may condemn it to destruction forthwith.
    • Rachel Carson

  • The "control of nature" is a phrase conceived in arrogance, born of the Neanderthal age of biology and the convenience of man.
    • Rachel Carson
