My name is Joel Cohen I’m Professor of Populations at the Rockefeller
University and at Columbia University in New York City.
My background is partially in public health and partially in applied mathematics.
WHY SHOULD YOU STUDY DEMOGRAPHY? Why should you consider taking a course in
demography in college? You will be growing up in the generation where the baby boomers
are going into retirement and dying. You will face problems in the aging of the population
that have never been faced before. You will hear more and more about migration into
the United States and in some cases, out, into Europe and out between rural areas and
cities. You need to understand as a citizen and as a tax payer and as a voter what’s
really behind the arguments. INTRODUCTION TO PROBLEMS IN DEMOGRAPHY I want to tell
you about the past, present and future of the human population. So let’s start with
a few problems. Right now, a billion people are chronically hungry. That means they
wake up hungry, they’re hungry all day and they go to sleep hungry. A billion people
are living in slums, not the same billion people, but there is some overlap. Living
in slums means they don’t have tenure in their homes, they don’t have infrastructure
to take the garbage away, they don’t have secure water supplies to drink.
Nearly a billion people are illiterate. Try to imagine your life being illiterate. You
can’t read the labels on the bottles in the supermarket, if you can get to a supermarket.
Two-thirds of those people who are illiterate are women and about 200 to 215 million women
don’t have access to the contraceptives they want so that they can control their own
fertility. This is not only a problem in developing countries;
about half of all pregnancies are unintended. So those are examples of population problems.
﻿ DEMOGRAPHY AS A TOOL FOR SOLUTIONS
Demography gives you the tools to address and to understand these problems. It’s
the study of populations of humans and non-human species that includes viruses like influenza,
the bacteria in your gut, plants that you eat, animals that you enjoy or that provide
your domestic animals. And it includes non-living objects like light bulbs, and taxi cabs and
buildings because these are also populations. And it includes the study of these populations
in the past, present and future using quantitative data and mathematical models as tools of analysis.
I see demography as a central subject related
to economics, to human wellbeing as in material terms; related to the environment, to the
wellbeing of the other species with which we share the planet; and the wellbeing and
culture which affects our values and how we interact with one another. WORLD POPULATION:
THE PAST The key fact you need to remember, is that
since the inventions of agriculture between 6,000 and 14,000 years ago, the population
of the earth, the human population, has grown 1,000 fold from approximately seven million
to nearly seven billion this year. Put three zeroes on the end of seven million, you get
seven billion. Over the same interval, the earth has not
gotten any bigger. The continents haven’t expanded 1,000 fold or at all. The oceans
are the same size as they were before. The atmosphere is the same size as it was before.
So the question that concerns a lot of people and me is whether the impacts that seven billion
people or more in the future will have on the earth will endanger, will threaten our
own well being and the well being of other species on the earth. We know that humans
have already caused the extinction of many species. The question is, is that going
to come back and bite us, and if so, in what ways?
Demography provides us with a reliable way to imagine and to reimagine the future. So
let’s get down to some nitty-gritty details here. About 2,000 years ago, there were
roughly a quarter of a billion people on the planet. Today, there are almost seven billion. More
than six-seventh of the growth since the beginning of humans 50,000 years ago has occurred in
the last 200 years. To go from a quarter of a billion to half
a billion took 16 centuries. So we reached about half a billion humans about 1600, more
or less. The population of the earth, the human population, if it were growing exponentially
would go from a quarter billion to half in 16 centuries and from half to one in another
16 centuries. What actually happened was that the human
population of the earth reached a billion around 1800. Why? Because of food stuffs
that came from the New World to the old; notably potato and corn or maize. And because many
of the people who were overcrowded in Europe went to America where there were fertile and
unoccupied lands to use. So the East/West exchange, the Columbian exchange across the
Atlantic liberated population growth in the European sector, there was a similar development
in Japan, an acceleration of population growth around the same time.
In 1800, the Industrial Revolution began and the population doubled from one billion to
two billion by 1930, 1927, we don’t know exactly. Why don’t we know exactly? Because
we didn’t have censuses that covered the whole world at that time. So it’s a retrospective
guess. So our doubling times went from 1,600 years
to 200 years, 1600 to 1800, to 130 years, 1800 to 1930. The next doubling from two
billion to four billion took only 44 years, 1974. So for
the last 2,000 years at least, except for the
Black Death in the 14th century, the population growth rate was going up, up, up, up and around
1965, it began
to decline. So in absolute terms and in percentage terms,
the number of people we are adding to the planet has begun to slow.
FERTILITY IS THE KEY TO UNDERSTANDING HUMAN POPULATION Since 1950, humans have made
the swiftest, voluntary change in reproduction in human history. Around 1950 the average
number of children per woman, per lifetime was very close to five. Today, the average
number of children per woman is about 2.5 or 2.6. In other words, billions of people
have changed their reproductive behavior to lower the number of children born in a lifetime
from five to two-and-a-half, but not everywhere.
In Sub-Saharan Africa, the decline has been much less. From perhaps 6.6 children to
5.1 over the half… the second half of the 21st century. To understand the consequences
of this fall to two-and-a-half children per woman, you need to know what is meant by replacement
level fertility. So I am going to introduce that by telling
you about the theory of bathtubs. A regular bathtub with no stopper. So two things happen
with a bathtub with no stopper. Water comes in and water goes out. And you can see intuitively
that if the amount of water coming in per minute exceeds the amount of water going out
per minute, the level of water in the bathtub is going to go up, and if the amount of water
come in per minute is less than the amount being drained out, the level in the bathtub
is going to go down. So the amount of water coming in that just matches the amount going
out keeps the level of the bathtub steady. Okay? That’s replacement level bathtub
water. Now, water coming in corresponds to births to the earth. And water going
out corresponds to death. And the level of the bathtub corresponds to the total population
size. So, if the number of births just matches the number of deaths, the population stays
steady and that’s the replacement level of fertility. Now, you’re asking
yourself, what is the replacement level of fertility? The answer is, it’s about 2.1
children per woman. There has been an amazing transformation in
the distribution of fertility across the world. In 2003, this was not in any newspaper anywhere,
but it was a very important event. In 2003, half of all the women in the world were having
replacement level or less. And now more than half of humanity lives in a country at
or below replacement level fertility. It’s the first time in human history that this
has happened. And it’s important. But you remember that the total fertility rate,
the average number of children per woman is at 2.5, not 2.1. And that’s because on
this curve, the green curve, the folks with high fertility are further to the right of
the red line than most of the folks with low fertility are to the left. So the average
is skewed to the right. So we still have a growing population. But this change is
continuing and how fast it continues is something that you as voters, as potential scientists,
as citizens will influence by what you choose to do about the 215 million women who have
an unmet need for contraception. WORLD POPULATION: THE PRESENT
So much for the past, let’s go on to the present. This is a population pyramid. It
is one of the basic descriptive tools of demography and you should understand what it is. Let’s
start with the left side of the picture. The horizontal axis, the width of the bar
tells you how many people there are and the vertical axis correspondence to age group.
So the lowest bar is for people aged zero to four with males on the left and females
on the right. The next bar is people age five to nine. The top bar is 95 to 100. And
what you see is that in the rich countries, there are about as many people aged, let’s
say zero to four as there are aged 85 or 90, but it’s basically a slender column.
Now compare it with the age pyramid for the poor countries. The base of the pyramid
is enormous compared to the number of elderly. So there are many more workers to support
the elderly, per elderly person. The width of the bar, again is the number of people,
so in the ranges from five to 14 of five to 19, that’s the school age population. It
means that the challenge of educating those children is much greater in the developing
countries than it is in the rich countries because those bars keep getting wider as the
developing countries pump in more children at the bottom of the pyramid and the age groups
move up with time as they get older. And so the larger school age population is followed
10 years later by a much larger military age population.
So if you look at the age groups 19 to 30 or 15 to 30, whatever the legal ages or illegal
ages are for fighting, you can see that the potential military force in the developing
countries vastly exceeds that in the rich countries. It doesn’t mean it’s military
power for them, it means they can afford a military engagement in a way that the human
resources of the rich countries make very difficult, increasingly difficult.
So where is the growth going? The demographic growth is happening in the countries that
can least afford to deal with the additional population.
What’s the average income? The reason we call a rich country as rich is that their
average income is about $32,000 a year per person and in the poor countries it is about
$5,000 a year. What fraction of people are living on less
than $2.00 a day? Nobody lives on less than $2.00 a day in the rich countries and 51 percent,
just about half in the poor countries. In other words, about 3.5 billion people on our
planet are living on $2.00 a day or less. So you might ask yourself, if things are so
bad there how is it that their population is growing so rapidly? And the fact is that
the difference in death rates is much smaller than the difference in fertility rates. So
even though a higher fraction of children die before they reproduce, the average number
of children that people have when they do reproduce in the poor countries more than
compensates for the increase in the death rate. So that’s why we have rapid population
growth at the same time that we have high fertility, high mortality because we had even
higher fertility. The global economic inequality means that
the most rapid demographic growth is associated with the people who have the least means to
take care of the children that are born and the people with the greatest need for reproductive
healthcare and services have the least means to afford it.
It’s an important general question, How does the rich world benefit from the prosperity
and development of the poor world? There are lots of different answers you can give.
One is, purely economic. Richer people in China and Africa will buy more American
music CD’s and more movies and more software and more high tech engines from General Electric
and more products because they have more means to buy. So that’s one kind of an answer.
A second is public health. There are millions
of flights in both directions from the poor countries to the rich countries every year.
And the microbes don’t know about passports. And they cross from Bombay or Mumbai to
New York just a fast as they go from New York to Mumbai. And when there are outbreaks
of drug resistant tuberculosis, those can travel around the world and they pose a danger
to me and to you guys. So we have an interest in the health and well being. A direct,
personal interest in the health and well-being of people in poor countries.
WORLD POPULATION: THE FUTURE So now we’ve talked about the demographic
past, and the demographic present. And next we’re gonna talk about the demographic future.
Woody Allen said, “Eternity is very long,
especially near the end.” So, we’re not going to talk about eternity. We are
only going to talk about the near term future. How much of the future is relevant to you?
Well, according to the United States Life Tables, published by the National Center for
Health Statistic. An 18-year-old in the United States in the year 2011 has a 91 percent
chance of surviving to 2050, 91 percent. Based on survival rates in 2006. If you behave
wisely and if economic and medial progress continues, you have at least that good a chance
of making it to 2050. So we’re going to talk about the world from now to 2050.
I can say with confidence that four things will happen over the next 40 years or so.
The world’s population will get bigger. It will grow more slowly. It will be older
in the sense that the fraction of older people will increase dramatically and it will be
more urban. And I’m going to go through each of those four to explain some of the
details. What we don’t know too much about is what
will be the future of migration, the future of household structures, and the future of
families. We have some ideas about that, but that’s relatively less certain.
THE FUTURE OF THE WORLD’S POPULATION : BIGGER This graph shows four different curves of
the history and future population out to 2050. At the top, the curve shows the anticipated
population if fertility remains at the level it is today and there’s no further decline
in fertility. That’s called the Constant Fertility Assumption. And it shows that
the world would go to about 11 billion people by 2050. However, if fertility drops as
it has dropped in the past, the medium projection of the U.N. Population Division is that population
would rise to about 9.1 billion by 2050. So that’s a difference of two billion. In
other words, we’re counting on a continuing decline in fertility to lower the population
size by about two billion by 2050. What we do between now and 2050 will have a huge
impact on how difficult it is to feed, house, shelter, educate, and provide health for the
billions of people on the planet in 2050. It will affect an enormous range of human
problems. It’s possible that population growth would
end before 2100 depending on the choices we make now. What choices am I talking about?
Choices like, educating women, providing credit to women in countries where women are
not now allowed to have credit. Providing reproductive healthcare so that women are
not forced as they are in some countries to have children when they don’t want to. Raising
the age of marriage so that 12-year-olds, 13-year-olds and 14-year-olds aren’t put
into marriage. There’s a lot of things we can do to raise people, including even
women, raise people’s control over their own lives. And we should be doing those
things. I am not trying to persuade people not to have children. I think that
is nuts, but I am trying to persuade people to have children that they can take care of
and do well for and to focus on quality of children rather than numbers. And, I view
demography rather broadly so I think you also need to know how your body works, how contraception
works, what’s more reliable, what’s less reliable, what are the factors that affect
contraception and how to take care of your own reproductive health and to help your children
take care of their reproductive health and your friends and your family.
THE FUTURE OF THE WORLD’S POPULATION : SLOWER GROWTH
So the first fact about the future is that the population is going to get bigger and
the second fact is that the population is going to grow more slowly depending… the
slowing will depend on what we do now. By 2050 in the medium projection from the
United Nations Population Division, the world will be growing by 31 million people a year.
What’s it doing now? It’s growing by 76
million people a year. In the poor countries, the population will
be growing by 32 million a year while in the rich countries; the population will actually
be declining by a million people a year. Already today
in 2011, population is declining in more than 50 countries. Not well-known.
What’s happening here is a shift in childbearing desires and action from quantity to quality
as people urbanize, as people get educated, as wealth improves, people are making greater
investments in a smaller number of children.
THE FUTURE OF THE WORLD’S POPULATION : OLDER So we’ve talked about population size, growth
rate, slowing. The next is aging. So by 2050, there will be about three times as
many elderly as children. This is the first time in human history that the elder population
has outnumbered the young population. So what? Well, aging affects energy demand.
So even if you are interested in the environment, you need to know about the age structure of
populations. Older householders spend, at least in the United States, India and China,
the three countries where it’s been studied in detail, spend more than younger households
measured by the age of the head on utilities services and healthcare. Utilities are the
most energy intensive part of the household budget. That’s not the only reason to
care. The rise in the fraction of elderly poses an increasing challenge to a relatively
reduced number of workers. And it’s possible that the well-being of elderly people could
improve, if they’re educated or could get worse if they are warehoused in old people’s
homes. We know for example, that people who are educated
in their youth have much lower disability when they get older. And in fact, disability
rates at any given age in the United States have been dropping by about one-and-a-half
percent per year for the last 25 years. So there are far fewer disabled elderly now than
there used to be. That’s the meaning of 60 is the new 40, 50 is the new 30. People
are healthier at older ages. That’s the result of investment in education in youth.
So, there are policy implications for a rising aged population, we better invest in
educating people when young. THE FUTURE OF THE WORLD’S POPULATION : URBAN
And the last of the four topics is cities. And I’m going to give you a very simplified
and boiled down demographic history of the first half of the 21st century. In 2000,
you could divide the world into two equal parts; half rural and half urban, about three
billion rural and three billion urban. In 2050 the rural population will still be at
three billion and the urban population will have doubled from three billion to six billion.
That’s a simplified history. All of those additional three billion urban people
will be in poor countries. The equivalent of a city of one million will
have to be built every five days from now to 2050 and all of them in poor countries.
So what’s the consequence? What is this massive shift towards urbanization
mean? If we under invest in cities, we can go from
a billion people living in slums today to four billion people living in slums. And
if we invest in the cities, if the real estate companies realize the opportunities, the incredible
demand that people have to live in decent housing, we could reduce the size of the slums.
So, I cannot give you a deterministic picture. I can tell you what would be awful. We could
have infectious diseases rampant. We could have warfare in the cities. We could have
disorder, but that’s not necessary. We could have clean water supplies; we could
have security for people in their houses. That doesn’t get as much news attention,
but the point I want to make is, we have choices about the future of cities and many things
about urbanization are positive. And I want to tell you a few of the things that are positive.
Not because they’re automatic, but because they are positive in fact and because we can
enhance the positive. Compared to rural areas, urban areas have
lower fertility rates. Why? I’m a woman on the farm. You might not think so, but
I am… okay. I’m a woman on the farm. The more children I have, the more help
I can have in collecting the water, collecting the fire wood and tending to the goats and
sheep. As soon as I move into a city, those children convert from an asset to a liability.
I have to buy them clothing. I have to send them to school. There are school fees,
the apartment is too small. The incentives completely shift direction. Urbanization
makes people want to have fewer children.
Cities also have higher usage of modern contraception and lower unmet needs for contraception. Why?
I am a woman; you might not know it… I don’t have to walk 15 miles to the nearest
health center and be exposed to the inspection of my husband’s friends when I go in for
contraception. No. When I’m in the city, I just go around the corner and it’s anonymous.
So, urbanization brings many features of liberation as well as changing the incentives.
Cities concentrate economic productivity.
Eighty percent of the world’s gross domestic product is produced in cities, although there
are only 50 percent of the world’s people in cities. Cities generate cultural assets,
educational resources, public health resources, medical care and they can promote energy efficiency.
Let me give you an example. This graph shows
the passenger transport, carbon dioxide per person. The denser the city, the lower the
amount of carbon dioxide per person. New York City is reported, according to the Mayor’s
office, to have less than one-third the carbon dioxide emissions per person of the U.S. average.
People take the subway, people ride the bus.
Cities also have hazards. Many cities are built along coastlines. Coastlines are where
the continental plates of the oceans collide with the continents. That means they are
prone to earthquakes. We just had the big example in Japan, but it’s true all around
the world. The Ring of Fire around the Pacific Ocean coincides with where the cities are
because cities are coastal. A lot of the world’s urban people live near the coastline
and that’s where the subduction zones are in California. So cities are vulnerable
to rising sea level, to coastal storms, cities concentrate people so they’re vulnerable
to infectious diseases, water supply attacks, and cities are excellent targets for military
and terrorist attacks, as we know in New York City and many other cities.
It used to be, battles were fought on battlegrounds. No more. They’re fought in cities. And
that will increasingly be the case as cities concentrate assets.
This is New York City as it is now. The red zone will be underwater if the water level
rises by one meter on the average. One meter is probably more than we’ll have in the
next 50 years, but could easily happen by the end of this century at current rates.
Now, a six meter rise would happen if the Greenland and Antarctic ice masses melted.
Six meters is about 20 feet. And that would be a catastrophe in many respects including
for me, there’s a little place over here in New Jersey which is my favorite nudist
colony. And it would be completely underwater. So that would be a terrible thing
to happen. Urban growth could affect the food supply.
Right now, cities occupy three percent of the land surface of the earth. The land,
the arable land, the land where we can grow food well is about 10 or 11 percent of the
land surface of the earth. It’s not surprising that many cities are smack in the middle of
the best arable land because that was where a food surplus could be easily produced without
having to ship the food. Now, if cities are going to double, we have another choice.
Do we double the area from three percent to six percent and eat up our arable land,
literally or do we double the density and keep the areas of the cities constant at three
percent. This is a choice for the future and it depends on zoning and culture and real
estate developers and economics and choices that we make as citizens. CONCLUSION
- FOOD: THE WORLD IS RUNNING OUT OF RESOURCES TO SUPPORT ITS GROWING POPULATION
How do we address the problems that we have.
There are three kinds of solutions that people have put forward; bigger pie, fewer forks,
better manners. The bigger pie people say we should use technology to increase production.
The fewer forks people say, we should use contraception to reduce population growth
and we should consume less material products. And the better manners people say, we should
eliminate violence, inequities between men and women, inequities between rich and poor,
inequities between young and old. We should eliminate rational subsidies and just make
things work more efficiently. Get rid of corruption.
We need all of those and I took a few years to try to figure out what’s my best way
to support those three strategies, all of them. And I came to the conclusion that the
best response would be to educate all children, boys and girls, well for 10 to 12 years, high
quality, primary and secondary education. I realized there is no chance of educating
people if their brains haven’t been fed adequately, in utero and after birth, especially
for the first three years. So I am now moving around to working on the problem
of getting food, adequate, good food, to pregnant women, lactating women, and infants up to
the age of three because there are many countries where by the time a child gets to school,
it’s too late the brain has lost its capacity to learn.
It comes back to my ecological interests in food. You can’t educate without a brain
that works. So now we’re talking about food. I started
this conversation saying that there are a billion hungry people, chronically hungry.
I want to come back to this. We depend on other species. Here is a list of what
other species provide to humans. And I’m going to read the list because it’s important.
Food for people, feed for our domestic animals, fuel, biofuel for example, and wood to burn,
biomass. And in many countries people burn dung. The waste products of animals. That’s
an important source of fuel. Fiber, so we depend on trees for many paper and other products.
Fascination, we love to go to the zoo and see animals. We love to see wildlife. When
people go out in nature, they’re thrilled if they see a deer or some other kind of wildlife.
In fact, in Central Park, the German tourists are thrilled to see squirrels. We find animals
fascinating. Pharmaceuticals, most of our drugs are natural products tuned up to serve
human needs. Animals provide transport, they carry people places. They provide traction,
they pull plows, they pull carts. Other species provide symbioses. I’ve talked
about the animals, not the animals, the bacteria that live in our guts. And they
provide infection. They can cause disease.
So the question I want to address now is can we grow enough food to bring us to 2050 without
catastrophe? These are data from the Food and Agricultural Organization in Rome. They
are estimates of the number of people in the world who are chronically under nourished
day after day. The current estimate is about 925 million people. That’s nearly a billion
and it is higher than the number has been in the last 40 years. Ninety-eight percent
of these people live in poor countries. Not only poor countries. Here is something that
shocked me and I hope it will shock you. At some point during 2009, 17.4 million U.S.
households, one household in seven in the United States, lacked enough money and other
resources to provide food for all members of the household.
The current level of food insecurity in the United States is higher than it has been since
the USDA started collecting the statistics by sample surveys in 1995. We are at an
all time high of hunger in this country. So the question you should be asking yourself
is, well aren’t we growing enough food? What’s the problem?
We’ve got seven billion people and there are a billion of them hungry. The answer
is, less than half of the grain that we grow goes into people’s mouths. Divide the
world’s grain into six equal pieces. One piece we use to make biofuels, starches, for
seed and other industrial uses; plastics. Two-sixths, we feed to our domestic animals
of the rich people, those who have the means to afford those animals and meet products.
Less than half, the other three-sixths goes directly into human mouths. We could be
feeding 11 billion, but we only feed half of that amount, 5 ½ billion into human mouths.
We put machines and animals in line before
people who don’t have money to express demand in markets. Hunger does not fit into our
economic theories. It’s economically invisible because people who are very poor, remember,
half a billion are only living on $2.00 a day or less. People who are very poor can’t
enter the market and plunk down their cash and say, “I want that.” They are invisible
economically. So my hunger does not affect your costs for grain. This is a problem
with our economics. And it’s a reflection of our values. CONCLUSION - WHAT’S
THE SOLUTION? So, here’s Joel’s formula for how to solve
the world’s problems. Well, population; let’s go at it with all
hammer and tongs. Eliminate all unintended pregnancies and educate all children to give
people control over their bodies and over their own lives.
Economics, open credits and markets to small farmers. A majority of the world’s farmers
are women. They are the ones out in the field actually doing the work. Eliminate
perverse subsidies in rich countries make it very difficult for poor farmers to enter
markets because they lower the price in artificial ways. And let’s raise the incomes of the
poor. Environment. Use the best farm lands for farms and internalize the external
costs of agriculture. Get rid of the pollution and use chemicals in a way that doesn’t
damage the environment. And fourth, promote healthy diets and value
adequate nutrition for every person. I would add one other thing under this culture question
and that is, we need to fund more research in agricultural productivity for the crops
that matter in poor countries. Not only for the industrial craps that fund our biofuel
habit, but for the crops that provide food to the poor.
CONCLUSION - SUMMATION When you walk away from this conversation, I hope that you’ll
remember that population interacts with economics, the environment and culture so that you immunize
yourself against people who will try to sell you an overly simple bill of goods. And
there are a lot of people. There are people who say, “Demography is destiny,” and
all we have to do is get a contraceptive in every pot and we’ll solve the world’s
problems. That’s wrong. And there are people who say all we have to
do is get the market right. Let the market take care of all the prices. In my view,
that is equally wrong and much more dangerous. There are people who say, “It’s only
a matter of law and getting the laws right.” Yeah, but it’s also a matter of technology
and contraception and economics. And there are people who say, “Forget about the people,
let’s just save the environment.” I don’t believe that because I’m a human
being and I value other human beings. We’ve got to get all of these things working together
and the environment can be on the side of human well being because poor rural people
depend directly on the environment for their sustenance. If they want to have a sustainable
sustenance, they have to have a sustainable environment. Demography makes it possible
to imagine and to re-imagine the future. I’d encourage any freshman, sophomore, junior,
senior, adult, high school student—I’m not age prejudiced—anybody who wants to
do three things to consider demography. It’s not the only field that offers these attractions
but it does offer them in spades. It’s really very attractive. First of all, demography
gives you tools and analytical perspectives to understand better the world around you.
That’s understanding. Secondly, it gives you equipment to solve problems mentally.
It’s mentally exciting; you really have to use your noggin, and if you’ve got one
use it or lose it. So it’s use it. And third, it is the means to intervene more wisely
and more effectively in the real world to improve the wellbeing, not only of yourself—important
as that may be—but of people around you and of other species with whom we share the
planet. So it prepares you to go out and do something that’s worth doing for
a larger good than only yourself. So there’s an old saying, “If I am not for myself who
will be; but if I am only for myself what am I; and if not now, when”? So now is
