It is astonishing to realise that the human species survived hundreds of thousands of years, more than 99 percent of its time on this planet, with a life expectancy of only eighteen years.

There is evidence that we are headed into what would be the planet's sixth mass extinction. It's hard to know for sure if you're in one because a mass extinction is an event where over 75 percent of the species on the planet die out over a - usually about a million-year period. The fastest it might happen is in hundreds of thousands of years.
Several times in Earth's history, rapid global warming occurred, apparently spurred by amplifying feedbacks. In each case, more than half of plant and animal species became extinct. New species came into being over tens and hundreds of thousands of years. But these are time scales and generations that we cannot imagine.
As someone who came to New York in the 1970s, I was, like so many of my friends, a certified member of what we now call the 99 percent - and I was a lot closer to the bottom than to the top of that 99 percent. At some point during the intervening years, I moved into the 1 percent.
Only 1 percent of the homosexual population in America will die of old age. The average life expectancy for a homosexual in the United States of America is 43 years of age. A lesbian can only expect to live to be 45 years of age. Homosexuals represent 2 percent of the population, yet today they're carrying 60 percent of the known cases of syphilis.
Children are forced to live very rapidly in order to live at all. They are given only a few years in which to learn hundreds of thousands of things about life and the planet and themselves.
Very few species have survived unchanged. There's one called lingula, which is a little shellfish, a little brachiopod about the size of my fingernail, that has survived for 500 million years, but it's survived by being unobtrusive and doing nothing, and you can't accuse human beings of that.
It's our human nature to explore. Tens of thousands of years ago, our species walked out of Africa, traveling far and wide across the entire planet, from the Arctic to the tip of Tierra Del Fuego, making us the most geographically diversified species on Earth.
Our flame is taking the normal depleted uranium - the 99.3 percent that's cheap as heck, and there's a pile of it sitting in Paducah, Kentucky that's enough to power the United States for hundreds and hundreds of years. You're taking that and you are converting it to plutonium - and then you're burning that.
I regard psychiatry as fifty percent bunk, thirty percent fraud, ten percent parrot talk, and the remaining ten percent just a fancy lingo for the common sense we have had for hundreds and perhaps thousands of years, if we ever had the guts to read.
When whales die, their bodies sink to the bottom of the ocean and over time become part of the marine sediment layer, where they can sequester the carbon dioxide they have accumulated during their life span, an average of 33 tons for a great whale species, keeping it out of the atmosphere for hundreds or thousands of years.
There are millions of different species of animals and plants on earth--possibly as many as forty million. But somewhere between five and fifty BILLION species have existed at one time or another. Thus, only about one in a thousand species is still alive--a truly lousy survival record: 99.9 percent failure!
When I am at a dinner table, I love to ask everybody, 'How long do you think our species might last?' I've read that the average age of a species, of any species, is about two million years. Is it possible we can have an average life span as a species? And do you picture us two million years more or a million and a half years, or 5,000?
Compared with the thousands of years in which human life has been on this planet, Christianity is a recent development.
We are animals, born from the land with the other species. Since we've been living in cities, we've become more and more stupid, not smarter. What made us survive all these hundreds of thousands of years is our spirituality; the link to our land.
Man has survived and prospered for more than 150,000 years on this planet without the help of use-by dates.
For millions of years, on average, one species became extinct every century.... We are now heaving more than a thousand different species of animals and plants off the planet every year.
