Answer 2

One big factor that was pointed out years ago when the world's population was 4 billion was when a population usually gets married. The example was that in many third world populations the average marriage age was near 16 years of age. Whereas in Ireland many women do not marry until 27 or even older. The example was not dynamic as Ireland overall population is of no real significance, However, if it was imposed on the rest of the world there would be a phenomenal difference seen. as the equations most powerful component - the doubling time - was dramatically altered. Certainly average number of children per family also has a aspect in this equation. Finally the last import is the life expectancy. In 1900 the American average life expectancy was 43 years old. The country reached 100 million in 1915, 139 years since its inception. 200 million was achieved in October of 1967, 52 years later. Now, 39 years later, we reach 300 million. This is definitely from the life expectancy component, as the other two have not changed dramatically, or may even have grown more toward less growth. Now however, we are living to 78 years average for men, and 80 years for women. Science fiction stories about the future abound with people being "eliminated" at a fairly young age (around 30) due to limited resources. Of course those rules were made by old men who were above the law. Similar to today's Congressmen, who send the young off to fight useless wars.

Answer 3

starting population
Birth Rate
Death Rate

Birth Rate and Death rate higher in underdeveloped countries but as the countries develop the Death rate falls before the Birth Rate

Answer 4

we've halted our very own evolution by our ability to adapt to easily approximately each and every difficulty, and via reversing the pass of nature. An occasion of it is in many circumstances seen in an immunity to the bubonic plague which had stepped forward in the process the dark a protracted time. some human beings DNA exchange into mutated to the ingredient that it actual resisted the plague bacterium completely. that individual same genetic mutation prevents that is descendants from getting the West Nile Virus. Humanity can't evolve by organic decision if we continually shop human beings alive. by our very own compassion as a species we've created a thank you to ward off organic decision and retaining human beings alive. The drain on components has been magnificent, besides the indisputable fact that it comes all the way down to a rely of human life.
