# What is the exponential formula for population growth on earth?

###### Wiki User
Nt=N0*e(r*t)

Nt = Future Population

N0 = Starting population

r = growth rate

t= number of years.

Note: e is a constant equal to 2.71828

MANY missing variables.. like disease, pestilence.. war..

Any time the RATE of increase is greater than one. For example : if a population were to double (note that 2 is greater than 1) each generation then it is referred to as exponential growth. Note also that there are now 7 billion people on Earth - exponential growth. What is "needed" for this kind of growth is an unlimited environment, since it does not exist in the real universe, exponential growth ALWAYS crashes.

They were not invented because they predated the first human beings. They existed at least millions of years before there was anyone to "invent" them.All novae produce radioactive elements and these decay exponentially. So exponential decay predates the formation of the solar system.I am not sure, but stellar fusion may be exponential. But, in any case, there are life forms on earth, like bacteria, that exhibit exponential growth. These bacteria, and therefore exponential growth, predate human beings by a few million years.They were not invented because they predated the first human beings.

Human population growth was gradual for most of the time people have existed, only in the last two centuries has population growth been rapid.

When the food source is depleted, a new predator is introduced, or balance is attained. The earth tends to find balance for the most part. As far as an "intelligent" species such as humans goes, probably never. or When the organisms compete

Because it doesn't take long for the organisms doing the growing to fill the entire Earth.

The higher the death rate is, the fewer people there are on the Earth.

Peace and a dark side. _____________ The moon has a spectacular view of earth, complete with earth cycles. _____________ An Earth orbit and more years (the moon is older). _____________ Also, zero population growth...

Carrying capacity is the term used to describe population growth being at a level that cannot sustain more growth because resources needed to sustain life are not enough.

For the next hundreds years: wars, pollution, population growth, AIDS, resource depletion, hunger, etc.

Prosperty seems to be the one factor that slows a population's growth. It is a natural paradox. Every other species on earth grows it population when there is plenty of food, but humans populations grow fastest in poverty stricken agricultural societies and slowest in wealthy industrial societies. France has the lowest birth rate in the world, and even the United States has had a negative growth rate for many years. Both countries rely on immigration to swell the ranks for their work force.

In 1916, the population of humans on Earth was 1.82 billion. The current population of the Earth is 7,249,044,399 as of July 2014.

The world is always changing. Technological advances help us live longer, but disasters such as earthquakes and hurricanes can lower our population. Humans are all over Earth, so it's hard to accurately predict our population.

Yes, Planet Earth has undergone several natural fluctuations in terms of global mean temperature (warming and cooling) over the past millions of years. BUT never before has the Earth shown a variation in temperature as seen in the past few decades. Human driven emissions coupled with our exponential growth are the driving forces for this unnatural change of our global temperature.

As of September 2008, the world's population is estimated to be just over 6.721 billion. In line with population projections, this figure continues to grow at rates that were unprecedented before the 20th century, although the rate of growth has almost halved since its peak of 2.2% per year, which was reached in 1963. The world's population, on its current growth trajectory, is expected to reach nearly 9 billion by the year 2042. (from wikipedia).

The population of Friends of the Earth Middle East is 40.

I ancient times polygamy was encouraged in order to sustain population growth. However, being that the earth is overpopulated, polygamy is more of a strain on the economy than a benefit.

In 1905, the population of the world was 1.68 billion people. By the year 2005, the population of the earth had increased to 6.51 billion people.

Nitrogen is important to life on earth for several reasons. It is essential for growth in the body and on earth.

The formula would be MO. (M representing any of the Alkaline earth metals)
