Life-support Quotes

In fact, giving society cheap, abundant energy at this point would be the moral equivalent of giving an idiot child a machine gun. With cheap, abundant energy, the attempt clearly would be made to pave, develop, industrialize, and exploit every last bit of the planet-a trend that would inevitably lead to a collapse of the life-support systems upon which civilization depends. (Paul R. Ehrlich)
Our intelligence and our technology have given us the power to affect the climate. How will we use this power? Are we willing to tolerate ignorance and complacency in matters that affect the entire human family? Do we value short-term advantages above the welfare of the Earth? Or will we think on longer time scales, with concern for our children and our grandchildren, to understand and protect the complex life-support systems of our planet? The Earth is a tiny and fragile world. It needs to be cherished. View quote
Carl Sagan
I could cut my leg off. I could cut my arm off. I could gouge an eye out. I'd still probably survive. But not very well. And that's what we're doing to the oceans. It's the life-support system of this planet. We've been dumping in it. We've been polluting it. We've been destroying it for decades. And we're essentially maiming ourselves. View quote
