The buzz behind 7 billion people: A milestone and a warning

Trying to assess the importance of the United Nations' upcoming celebration of the global population reaching 7 billion is sort of like trying to assess the meaning of life.

As the countdown clock to the date keeps ticking, and people keep buzzing about the number, many are trying to figure out the real importance of hitting that marker.

The Wall Street Journal proposed the question: "How Do You Get to 7 Billion People?" The article raised the question: Exactly how do you know that we are reaching this symbolic number on a date set by the United Nations, given that some countries don't have full census data?

"The world's population will hit seven billion on Oct. 31. Or maybe not until next year. Or maybe it has already happened.

"No one knows for sure. But that hasn't stopped the United Nations from picking the last day of the month as the symbolic date, christening it as 7 Billion Day."

Perhaps the occasion will allow us to realize that we need to pay more attention to better tracking our growth and impact - our literal footprint on Earth. For some, there will be the typical celebrations: a baby wrapped in a blanket declared the 7 billionth person to enter this world as hospitals debate which baby was actually the one that hit the marker, similar to what has happened with milestones in the past.  (If you're curious where you fall in the mix, Population Action International has a handy "What's your number?" interactive based on your birth date.)

But it seems like this time around, if social media and traditional media are any indication, this milestone is about a little more than just balloons and fanfare. The Wall Street Journal wrote:

"While seven billion is a nice round number, knowing the identity of the lucky baby or the exact moment the threshold is crossed isn't really any more important than pulling over to the side of the road to bask in your car's 100,000th mile. But the building blocks for world population estimates — national demographic statistics and characteristics — are used by governments, businesses and aid groups to plan spending and spot potential trouble spots."

In a growing and ever-changing economic and technological world, this may be the time to look at where we've been, what we're going through now and what challenges lie ahead for such a massive population.

iReport: What does 7 billion look like

And with movements like Occupy Wall Street spreading across the globe to share growing discontent about government institutions' ability to deal with our problems and growing debt, the 7 billion mark poses questions about whether those concerns will be passed on to future generations.

"The milestone of 7 billion is marked by achievements, setbacks and paradoxes," a United Nations Population Fund report begins. (Read the report in PDF form)

The U.N. says it believes the world can thrive as it reaches the milestone, but the report also looks at the ways that countries are growing and changing, as well as how they can tackle critical challenges and prepare for the arrival of billions more people this century. Those challenges include empowering young people with economic opportunities; planning for the growth of cities; developing programs to share and sustain the Earth's resources; and improving education, including sexual education.

The U.N. has teamed up with the company SAP to help make those decisions easier by creating a widget on the site that allows you to assess the world's population by age, socioeconomic status and education levels, and to compare trends from country to country. The goal is to help governments assess their needs for the future.

After all, with more people comes the need for more resources.

Jeffrey D. Sachs, the director of The Earth Institute at Columbia University, writing for CNN, says the occasion marks a huge task for us.

"The arrival of the 7 billionth person is cause for profound global concern. It carries a challenge: What will it take to maintain a planet in which each person has a chance for a full, productive and prosperous life, and in which the planet's resources are sustained for future generations?

"How, in short, can we enjoy 'sustainable development' on a very crowded planet?"

That crowded planet may cause some global issues. Those include the health concerns caused by the waste that 7 billion people create, according to a LiveScience report on

MSNBC's photo blog takes a visual look at the effect that we have on the world each day and how we tax the environment: through deforestation, pollution from developing countries and traffic jams, as well as the struggle to cultivate all of the food and crops necessary to feed our growing population. That imprint will only grow as more of us inhabit the planet, the accompanying article says.

And Roger Martin's article in the UK's Guardian newspaper says the growing population could cost us the planet we live on in the way we now know it.

"Every additional person needs food, water and energy, and produces more waste and pollution, so ratchets up our total impact on the planet, and ratchets down everyone else's share – the rich far more than the poor. By definition, total impact and consumption are worked out by measuring the average per person multiplied by the number of people. Thus all environmental (and many economic and social) problems are easier to solve with fewer people, and ultimately impossible with ever more."

"On a finite planet, the optimum population providing the best quality of life for all, is clearly much smaller than the maximum, permitting bare survival. The more we are, the less for each; fewer people mean better lives.

TV One in New Zealand took a look at the meaning of the number, but from the perspective of the tax burden it may bring on a growing population of aging people.

"Richard Bedford, an expert on population changes from Waikato University, told TV ONE's Breakfast, that young taxpayers' ability to cope is 'the big $64,000 question.'

"By 2030, more than a third of the population in a number of Western countries will be aged over 65."

For some, the projection has come with gloom and doom and questions of "are we prepared?" for the population growth ahead.

A National Geographic cover story from January, titled "Population 7 Billion," examined the history behind the global moment and fascination with how well and how long our civilization can continue to coexist with our surroundings.

"For centuries population pessimists have hurled apocalyptic warnings at the congenital optimists, who believe in their bones that humanity will find ways to cope and even improve its lot. History, on the whole, has so far favored the optimists, but history is no certain guide to the future. Neither is science," Robert Kunzig wrote. "It cannot predict the outcome of People v. Planet, because all the facts of the case — how many of us there will be and how we will live — depend on choices we have yet to make and ideas we have yet to have."

    How is people think the world is overpopulated? It's not overpopulated. It's overpopulated with ghost town. Stock market crash in 2008. Why can't you read book or learn to use GOOGLE MAPS?

    Solution to the problem. Less Procreation !!! Lets sterilize some of these people! Do we have to let everyone have 10 kids! We limit population on deer and other animals, why not ourselves!

    Not good. We probably have already surpassed the Earth's ability to feed all of us. There certainly is not meaningful work for all of us. War, famine, plagues and other woes will be Mother Nature's attempt to kill off half or two thirds of us, but it may not work. Sort of glad I'm in the last third or so of my life and won't be around to see the carnage. By the way, I come from a family of childless and one-kid couples.

    I read the OMG news stories today about Earth's population reaching 7 billion people and how the world is in dire trouble because of over population. So, I decided to do a calculation to put it into perspective. I am fairly sure my math is correct, but feel free to fact check:

    1. There is: 268,581 sq miles in Texas
    2. There is: 27,878,400 sq feet in mile
    3. There is: 7,487,608,550,400 sq feet in Texas
    4. Divide the Earth's entire population: 7,000,000,000 into sq feet in Texas: 7,487,608,550,400
    5. Each person on Earth could fit into Texas and have 1069.66 sq feet of space of their own.

    You could carry the calculation further and place a family of four into a 1500 sq foot home and have 2778.64 sq feet per family left over for infrastructure—roads, schools, shopping, etc., etc

      your premise is highly flawed. There is not enough food and water to sustain this population.

      There you go scenic boy. How many bears can live within a square mile.On the other hand maybe we can just run pipes and wires every where and put metters in to charge people.

      I simply did the math and said nothing about being able to sustain everyone on earth in a place the size of Texas. But, I wanted to put into perspective just how many people we are talking about.

      The key is to figure out how to get at least a dollar from each person. That's all I care about when I read this article.

      But you are on to something. We can plan to build self sustaining cities that run on green energy and recycling. We can farm and feed ourselves and manage our growth. someday if we play our cards right we can go into space and find new frontiers. We must take care of our planet first. save the animals and wild life and learn to live together . Salvation is at hand !

      It's believed that each human needs about 33 acres to live healthy for their food (farming and livestock needs), shelter materials, clothing materials and waste needs.

    3 or 4 people are born every second, making it rather difficult to say who is the 7 billionth.

    12 square feet per family of four? You fail to consider vertical living. Add another 12 square feet for each level of your box.

    On a more serious note: Stupid people shouldn't breed. Smart ones should breed much less. There. Problem solved.

      Indeed. Too many worthless people who only know how to procreate. They're barely worth the cost of the bullet, nevermind the tens of billions of dollars wasted to sustain them on welfare.

    There's plenty of space on this earth for 7 Billion people. If you only take 5 countries: USA, Canada, Mexico, England, and Australia – those alone you have enough land for every single person to have 1 acre each with 10,000,000 acres to spare. And then there's the entire rest of the world! People just need to spread out!

    7 billion mark, most born in developing countries. With politicians that work for corporations and passive citizenry, the 1% will continue to get more of the wealth. The governments will have less power to stop huge corporations. Corporations have the money, political power, money moves the earth now, and the majority will live in poverty. Seems like corporations are now the "kings" of the past, and the masses are peasants working for their king, but they have managed to do it legally and with out permission. Welcome to the 21st century monarchy; the people= DEBT SLAVES. How much do you owe? Will you do anything about? Probably not.
