Of course, a positive growth rate might be taken as evidence that a population is below its optimum. — © Garrett Hardin
Of course, a positive growth rate might be taken as evidence that a population is below its optimum.
The rate of population growth in the United States is slightly below that required to reproduce itself.
The growth of the American food industry will always bump up against this troublesome biological fact: Try as we might, each of us can only eat about fifteen hundred pounds of food a year. Unlike many other products - CDs, say, or shoes - there's a natural limit to how much food we each can consume without exploding. What this means for the food industry is that its natural rate of growth is somewhere around 1 percent per year - 1 percent being the annual growth rate of American population. The problem is that [the industry] won't tolerate such an anemic rate of growth.
The optimum population is modeled on the iceberg- eight-ninths below the water line, one-ninth above.
The rate of growth of the relevant population is much greater than the rate of growth in funds, though funds have gone up very nicely. But we have been producing students at a rapid rate; they're competing for funds and therefore they're more frustrated. I think there's a certain sense of weariness in the intellectual realm, it's not in any way peculiar to economics, it's a general proposition.
If fertility drops much below 2.1 babies per woman, the population will shrink unless it is offset by higher immigration. For this reason, a demographic cloud hangs over China. It may be the first country to grow old before it grows rich. ... Its fertility rate is below two and its working-age population will start to decline around 2015.
The first law of sustainability: population growth and/or growth in the rate of consumption of resources cannot be sustained
The Planetary Regime might be given responsibility for determining the optimum population for the world and for each region and for arbitrating various countries’ shares within their regional limits. Control of population size might remain the responsibility of each government, but the Regime would have some power to enforce the agreed limits.
A combination of very rapid population growth over the last 50 years and reckless economic growth during the same time has stored up massive problems for societies the world over. No nation is immune. The scientific evidence tells us all we need to know: carry on with business-as-usual growth-at-all-costs, and we're stuffed
I was chairman of the steering committee for agriculture when we set up the target of 4% growth rate. I had written that if you want to achieve 4% growth rate in agriculture, you should have 8% growth in animal husbandry and fisheries and 8% in horticulture.
If the growth rate is so good that in another ten years the company might well have quadrupled, is it really of such great concern whether at the moment the stock might or might not be 35% overpriced?
We need to continue to decrease the growth rate of the global population; the planet can't support many more people.
I think the ethos for Gov. Romney is to use a whole variety of policies, of which tax policy is one, to try to raise the rate of growth. We've had a recovery from the financial crisis that would be well below what one might normally expect for a recovery from such a deep recession. And to counteract that we need better tax policy.
Of course I know our economic growth can't match our population growth so of course I know we'll all get poorer until we get that number down - don't tell me, tell the other idiots!
I've made a commitment that state spending in Vermont won't grow any more than the rate of inflation plus population growth.
In China, it was always said that a double-digit rate of growth would be dangerous. Now, the country has a growth rate of 6.9 percent and suddenly that is supposed to be a catastrophe for the global economy.
A man doesn't amount to something because he has been successful at a third-rate career like journalism. It is evidence, that's all: evidence that if he buckled down and worked hard, he might some day do something really worth doing.
