There are now more than seven billion people on the planet. If trends don't reverse, by 2050, we'll be closer to ten billion.

We have 7 billion people on this planet. It’s not that there’s not enough room on this planet for 7 billion people, it’s that the energy needs for 7 billion people are 7 billion people’s worth of energy needs, as opposed to, say, 2 billion. Imagine how much pollution would be in the air and the oceans if there were only 2 billion people putting it in? So yeah, we’re already overpopulated.

Global human population has doubled three times in the past 200 years, surging from 1 billion in 1820 to 2 billion in 1927, to 4 billion in 1974, to 8 billion today. Its highest rate of growth was in the 1960s, at over 2 percent per year; that rate is now down to 1.1 percent. If growth continues at the current rate, we’ll have about 18 billion people on Earth by the end of this century. All of this would be fine if we lived on a planet that was itself expanding, doubling its available quantities of minerals, forests, fisheries, and soil every quarter-century, and doubling its ability to absorb industrial wastes. But we don’t. It is essentially the same beautiful but finite planet that was spinning through space long before the origin of humans.

I was born into a world of just under two billion people today there are nearly seven billion of us. Whenever I hear those numbers I can honestly say I find it incredible, triple the number of human beings in what seems like the blink of an eye and the world transformed utterly. Human population density is a factor in every environmental problem I have ever encountered, from urban sprawl to urban overcrowding; disappearing tropical forests to ugly sinks of plastic waste, and now the relentless increase of atmospheric pollution. I've spent much of the last 50 years seeking wilderness filming animals in their natural habitat and, to some extent, avoiding humans. But, over the years, true wilderness has become harder to find. m1s58-m3s03

If there were a billion people living on the planet, we could do whatever we please. But there are nearly seven billion. At this scale, life as we know it today is not sustainable.

The Earth is not just an ordinary planet! One can count, there, 111 kings (not forgetting, to be sure, the Negro kings among them), 7000 geographers, 900,000 businessmen, 7,500,000 tipplers, 311,000,000 conceited men — that is to say, about 2,000,000,000 grown-ups.

The population of the earth today doubles regularly. If you were to draw up the population growth on a chart you would see that it goes back to zero about five thousand years ago. If man has been here millions of years like evolutionists teach, where is the population?

In what year will the human population grow too large for the Earth to sustain? The answer is about 1970, according to research by the . In 1970, the planet's 3 and a half billion people were . But on this New Year's Day, the population is 8 billion. Today, wild plants and animals are running out of places to live.

".."consider this. It took the earth's population thousand of years-from the early dawn of man all the way to the early 1800s-to reach one billion people. Then astoundingly, it took only about a hundred years to double the population to two billion in the 1920s. After that, it took a mere fifty years for the population to double again to four billion in the 1970s. As you can imagine, we're well on track to reach eight billion very soon. Just today, the human race added another quarter-billion people to planet Earth. A quarter million. And this happens ever day-rain or shine. Currently every year er 're adding the equivalent of the entire country of Germany.

It has been estimated that the world human population stood at about one billion around the early 1800s, which was roughly about when the industrial adventure began to gain traction. It has been inferred from this that a billion people is about the limit that the planet Earth can support when it is run on a nonindustrial basis. World population is now past six and a half billion, having more than doubled since my childhood in the 1950s. The mid-twentieth century was a time of rising anxiety over the “population explosion.” The marvelous technological victory over food shortages, including the “green revolution” in crop yields, accelerated that already robust leap in world population that had begun with modernity. Dramatic improvements in sanitation and medicine extended lives. Industry sopped up expanding populations and reassigned them from rural lands to work in the burgeoning cities. The perceived ability of the world to accommodate these newcomers and latecomers in a wholly new disposition of social and economic arrangements seemed [to] be the final nail in the coffin of Thomas Robert Malthus, the much-abused author of the 1798 [groundbreaking work] An Essay on the Principle of Population as It Affects the Future Improvement of Society.

We are one of 8 million or so species on this planet.

First we've got population. Now, the world today has 6.8 billion people. That's headed up to about nine billion. Now, if we do a really great job on new vaccines, health care, reproductive health services, we could lower that (forecast) by, perhaps, 10 or 15 percent, but there we see an increase of about 1.3 (per year).

It's the 21st century and still we have no universally agreed upon definition of life. It seems the universe does not care about our desire for tidy categories and tight descriptions. Our intellectual comfort is irrelevant to reality. When it comes to life, gray zones and blurry boundaries abound. This is bizarre considering life has been on our planet for more than 3.5 billion years and it's all around us now. Life saturates Earth's surface zone, from more than a mile deep in the crust to the stratosphere miles above. Its diversity and overall success are staggering, difficult to comprehend. For example, some scientists estimate that there are more than one trillion species alive right now. In total, Earth may have hosted more than 100 trillion species so far. Life is no stranger to us. And yet, what is it?

We are experiencing an accelerated obliteration of the planet’s life-forms — an estimated 8,760 species die off per year — because, simply put, there are too many people. Most of these extinctions are the direct result of the expanding need for energy, housing, food and other resources. The , , , , , , and are all victims of human overpopulation. Population growth, as E. O. Wilson says, is "the monster on the land." Species are vanishing at a rate of a hundred to a thousand times faster than they did before the arrival of humans. If the current rate of extinction continues, Homo sapiens will be one of the few life-forms left on the planet, its members scrambling violently among themselves for water, food, fossil fuels and perhaps air until they too disappear. Humanity, Wilson says, is leaving the , the age of mammals, and entering the Eremozoic — the era of solitude. As long as the Earth is viewed as the personal property of the human race, a belief embraced by everyone from Christians to Marxists to free-market economists, we are destined to soon inhabit a biological wasteland.
