A Quote by Paul R. Ehrlich

By 1985 enough millions will have died to reduce the earth's population to some acceptable level, like 1.5 billion people. — © Paul R. Ehrlich
By 1985 enough millions will have died to reduce the earth's population to some acceptable level, like 1.5 billion people.
When I was born, the world's population was 3.5 billion. There are now 6.8 billion people on the planet. By 2050, that's expected to rise to 9.4 billion. What's more, the Earth's resources aren't growing; they're decreasing - and rapidly.
I always give the analogy of the Earth at Night picture, of 7.3 billion of us, right? And everyone says, "Well, that's population." Well, if you took the entire world's population and you lived at the density of Manhattan proper - not a bad place to live - how much space do 7.3 billion people take up? The state of Colorado. At which point I end my lectures, because I want you to be thinking ... is this really a question of population, or is this a question of land use and resource consumption? And let's face it, the top 1.3 billion of us are doing all the damage. Sorry.
Out of a human population on earth of four and a half billion, perhaps twenty people can write a book in a year. Some people lift cars, too. Some people enter week-long sled-dog races, go over Niagara Falls in a barrel, fly planes through the Arc de Triomphe. Some people feel no pain in childbirth. Some people eat cars. There is no call to take human extremes as norms.
There is no such thing as an acceptable level of unemployment, because hunger is not acceptable, poverty is not acceptable, poor health is not acceptable, and a ruined life is not acceptable.
There is a single theme behind all our work-we must reduce population levels. Either governments do it our way, through nice clean methods, or they will get the kinds of mess that we have in El Salvador, or in Iran or in Beirut. Population is a political problem. Once population is out of control, it requires authoritarian government, even fascism, to reduce it.
I think that humans are also set up to survive. We're not as small as rats, but we make up for that by being intelligent enough to make our own hiding places and to adapt to new habitats, even if they are changing very quickly. We have an enormous population, and can afford to lose billions of people without suffering very much as a species. Indeed, some would say losing five billion people would be good for the planet - I disagree with them, but can't deny that we would do just fine if there were two billion of us or even one billion.
Obama has always been, while President, has been close to the Queen of England, and the Queen of England has a standing policy now, which has been going on for some time, saying that we have to reduce the human population, on this planet, from 7 billion people down to less than 1! That is her avowed policy.
Population diminishing, even in Japan and Italy, the population is diminishing. When society can reach a sustainable place or gain comfortable income, then people tend to have fewer children. Poverty makes a chain reaction of having many children. So when society reaches some kind of level, then it will turn toward getting a smaller population.
If you make a street poster and literally paste it on the street in a city like New York, where it's such a mixed population and so densely populated, and it stays up for a full week and doesn't get covered up by something else or pulled down, you will have fifty thousand people who will have seen it. It will be the poorest of the poor - some homeless man who lives on the street will see it and probably appreciate it, or some businessman or landlord will see it. Everyone will see it. And whether or not they even realize that they saw it, on some level it's affecting their consciousness.
The population of earth has reached 7 billion people, every single one of whom send you irritating emails to join something called "LinkedIn."
At the beginning of the 20th century, there were less than 3 billion people on the earth, closer to 2 billion. By all measures that we can come up with right now,. with the lifestyle and consumption pattern of the Western industrial civilization, we can probably sustain about 2 billion people on this earth. We already have over 6 billion. China and India are aspiring to come on as industrial nations, aspiring to the lifestyle of the Western world, and it simply can't happen.
The Earth's population will be culled from today's 6.6 billion to as few as 500 million, with most of the survivors living in the far latitudes - Canada, Iceland, Scandinavia, the Arctic Basin.
People always like to have a good time and laugh, and, [among] the vast majority of the seven billion people on this earth, one thing that we all have in common is at some point we all need to pair up and find some sort of significant other, some sort of romantic counterpart.
The use of refined petroleum as fuel, which began in the 1850s, freed hundreds of millions of people from the toil of centuries, gave hundreds of millions more a life of ease and plenty, and, by allowing great cities to feed themselves from every corner of the world, multiplied the population of the earth fivefold.
For the planet's sake, I hope we have bird flu or some other thing that will reduce the population, because otherwise we're doomed.
After the earth dies, some 5 billion years from now, after it's burned to a crisp, or even swallowed by the Sun, there will be other worlds and stars and galaxies coming into being - and they will know nothing of a place once called Earth.
