A Quote by Carl Sagan

As agonizing a disease as cancer is, I do not think it can be said that our civilization is threatened by it. ... But a very plausible case can be made that our civilization is fundamentally threatened by the lack of adequate fertility control. Exponential increases of population will dominate any arithmetic increases, even those brought about by heroic technological initiatives, in the availability of food and resources, as Malthus long ago realized.
If the population curve is on an exponential growth, and the resources are on an exponential decline, what happens first is you get increases in wealth discrepancy, which means that you get rich pockets of gated communities with security guards outside them, and you get more and more poverty outside that area.
People inside of belonging systems are very threatened by those who are not within that group. They are threatened by anyone who has found their citizenship in places they cannot control.
People are only mean when they're threatened… and that's what our culture does. That's what our economy does. Even people who have jobs in our economy are threatened, because they worry about losing them. And when you get threatened, you start looking out only for yourself. You start making money a god. It is all part of this culture.
If we don't watch out, the pleasure o be gained from the discriminating enjoyment of food will be lost. It may not be long before the art of fine cooking is viewed as the invention of a handful of snobs. . . . A whole aspect of living well, of civilization itself, is threatened with extinction.
You do have this circumstance in Karachi that because people know things are changing, the stakes are higher. Everyone is thinking, "My home is threatened, my job is threatened, my identity is threatened, my world is threatened." And that creates a very particular sort of climate, that is linked.
When we shift our public dollars away from our schools and city services and into company developments, it increases the root causes of poverty: unemployment, underemployment, lack of community resources, and lack of quality public education.
I don't think that our problem, our jobs problem, is fundamentally a problem of trade. I think it has much more to do with the fact that we have not sufficiently educated our population. We have not got out of this great recession with adequate stimulus and adequate fiscal and monetary policies over all.
We live in a society that has no adequate images anymore, and if we do not find adequate images and an adequate language for our civilization with which to express them, we will die out like the dinosaurs.
The most obvious risk was that the Russian speaking population was threatened and that the threats were absolutely specific and tangible. This is what made Crimean residents, the people who live there, think about their future and ask Russia for help. This is what guided our decision.
I feel this is very important for us to have serene buildings because our civilization is chaotic as it is, you see; our whole machine age has brought about a chaos that has to be somehow counterbalanced, I think.
A young person in Africa with a smartphone has more communications technology than the U.S. president had 25 years ago. So if the tools to change the world are now in everyone's hands, then the individuals now have the power that only governments and corporations used to have a couple of decades ago. I get excited by how that increases our capacity to be creative, and how that increases our capacity to create transformative things in the world.
Loving Your Enemies... Far from being the pious injunction of a utopian dreamer, this demand is an absolute necessity for the survival of our civilization. Yes it is love that will save our world and civilization; love even for our enemies.
Most of the human body disease such as Obesity, Cancer, Heart disease are linked with our food which we eat in our day to day life. If people are eating health food than how come there be more than 50% death from heart and cancer disease alone in a developed nation such as USA?
Population, when unchecked, increases in a geometrical ratio. Subsistence increases only in an arithmetical ratio. A slight acquaintance with numbers will shew the immensity of the first power in comparison of the second.
The more various our artificial necessities, the wider is our circle of pleasure; for all pleasure consists in obviating necessities as they rise; luxury, therefore, as it increases our wants, increases our capacity for happiness
We have progressed in a technological sense, but I'm not so sure whether we have progressed in a civilizational matter - the quality of the civilization has not improved. It's a civilization that's in love with technology but forgetting about the human side of it and the destructive tendency in human civilization has not been faced.
