Transcript of Population Growth

The History of how many Humans
Live on this place...Earth
To start, where did these humans come from?
There are lots of theories!
Lets make a list of all the theories we have ever herd of. OK, so regaurdless of which theory is true,
could we say that its TRUE that Along time ago there
were not as many humans as today The amount of humans was not a problem.
In fact the problem was there were not enough humans.
People had to have big families with lots of boys who could do the hard work. (T. Malthus) Who is Thomas Malthus? The Reverend Thomas Robert Malthus FRS (13 February 1766 – 23 December 1834), was a British scholar, influential in political economy and demography. Malthus popularised the economic theory of rent.

Malthus has become widely known for his theories concerning population, and its increase or decrease in response to various factors.

Malthus thought that the dangers of population growth would preclude endless progress towards a utopian society: "The power of population is indefinitely greater than the power in the earth to produce subsistence for man". As an Anglican clergyman, Malthus saw this situation as divinely imposed to teach virtuous behaviour. Believing that one could not change human nature, Malthus wrote: "Must it not then be acknowledged by an attentive examiner of the histories of mankind, that in every age and in every State in which man has existed, or does now exist

That the increase of population is necessarily limited by the means of subsistence,

That population does invariably increase when the means of subsistence increase, and,

That the superior power of population it repressed, and the actual population kept equal to the means of subsistence, by misery and vice." What is Overpopulation?

Do you think it is real? Overpopulation is a term that refers to a species growing past the point where their environment can sustain them.

What is sustain?

What environment?

How many more humans are there
today than before? Video time Why has the last 150 or so years
seen such a population BOOM? What does exponential growth have to
do with overpopulation? Along time ago there was a king.
The king was kind of a jerk face and
was not all that nice to his people. Anyhow,
he needed the help of the towns mathmatician
for some chess problems he had.He kept loosing to the French! The mathmatican met with the
king and told him he would help him for pay. The king said, "what
do you want?" The mathmatician said, each day I meet with you I want you to
put double the amount of wheat you had put the time before and you can start with
one grain of wheat." The king thought, "O what a fool, I would have paid him 1000 peices of
wheat every day." The king got 30 lessons, who got the better deal?
