World population topped 7.3 billion earlier this year.
Just to put it into perspective, when we add 1/10th of a billion in a little over a year, it’s a number equal to the combined population of our four most populous states: California, Texas, New York and Florida.
When I was born in 1945, there were less than 2.5 billion people on this planet. During my lifetime, our population has tripled. And, if I live long enough, it may even quadruple during my watch.
Let’s take a look at population growth numbers since humans emerged as a species 200,000 years ago:
- It took us 199,800 years to reach one billion in 1804.
- But only 123 years to reach two billion in 1927; then, we needed just:
- 32 years to reach 3 billion in 1959
- 15 years to reach 4 billion in 1974
- 13 years to reach 5 billion in 1987
- 12 years to reach 6 billion in 1999
- 12 years to reach 7 billion in 2011
- 4 years to reach 7.3 billion in 2015
The good news is that the number of years it takes to add one billion people appears to have stabilized at twelve or thirteen. The bad news is that, if we continue adding one billion every 13 years, we’ll reach TWELVE BILLION in 2076, when the average age of my grandchildren will be 70, which is my age today.
To celebrate my 70th this year, I skied down a mountain and across a pond; well, partway across a pond (See video below). I wonder what my grandkids will be doing when they turn 70? What kind of world are we leaving for them? I say “we” because most of the damage inflicted by humans on this planet’s fragile ecosystem has occurred during my lifetime.
To clarify, I am not just talking about population growth. That is just part of the problem. The other part is the way we live–as millions of people start to eat meat, drive cars, fly in jet airplanes, use air conditioning and live in big homes–the rate of depletion of finite natural resources keeps rising. In a recent blog, I posted some of those numbers from Emmott’s book, TEN BILLION:
- In 1960, we flew 62 billion passenger miles. In 1980, we flew 620 billion miles, and in 2012, the number was 4 trillion.
- As for automobiles. In 1960, there were 100 million on the road. In 1980, there were 300 million. Now there are one billion.
- It gets worse, we’re currently on track to produce four billion cars in the next forty years–after it took us 112 years to produce the first two billion.
- We’ll also need to produce more food in those forty years than we have produced in the past 10,000 years combined.
Time out for one minute. Enjoy!
Meanwhile, back to the harsh reality of the 21st century on planet Earth.
Doom and Gloom? NO! Sometimes, I feel like I am repeating the same message with every article or chapter that I write. But I am not a “doom and gloom” kind of guy. I am generally an optimist, but first and foremost, I am a realist.
And the REAL DEAL about all of the above is there is no way that we can support 12 billion people on this planet–without radically changing the way we live. Stephen Emmott summed it this way in his book:
Deforestation. Desertification. Species extinction. Global warming. Growing threats to food and water. These driving issues of our times are the result of one huge problem: Us.
And that hope hinges on figuring out a way to “radically” change our food choices. By simply taking the animal out of the equation, we can easily feed the world’s 7.3 billion with 75% less land and water, while reducing energy consumption by up to 30 percent. Just think about the ecological impact of those three things.
As all of that land (formerly used for growing food animals) is returned to nature, we take a big step in the right direction when it comes to healing our fragile ecosystem. We also buy ourselves enough time to solve the more difficult challenges of overpopulation, overconsumption and over-dependence on fossil fuels. Even Stephen Emmott agrees that moving toward a plant-based diet for humans would result in a HUGE positive impact on our environment.
The beauty about changing our food choices is twofold. First, it would have a greater positive ecological impact of ALL other possible initiatives combined. Second, since any person can change their food choices overnight, this powerful initiative can happen very quickly. Other challenges, like curbing overpopulation or overconsumption, will take many decades, if not centuries to resolve.
What can you do? You can start by getting the “animal out of the equation” in your own diet. You can also become a part of this discussion. You can ask other people to look at the simple arithmetic that any 3rd grader could understand. You can challenge the “leaders” that you know about the unsustainable nature of our lifestyle. You can ask them why no one in power ANYWHERE is talking about this crucial topic. Finally, you can invite me to speak at your company, church, university or club.
For more information, take a look at a few of my earlier blogs on this topic. Let’s not let our entire “world” go the way of Easter Island (second article below). The first article is about my grandchildren’s lives–in the last half of this century.
