One reason the population has grown so fast in the last 100 years is that the Death Rate has gone down. Better health care and living conditions, as well as more plentiful food supplies, have decreased the death rate.

∙ 9y agoPopulation growth rates for any species are, by nature, exponential rather than linear. That means that instead of adding some number for each successive generation, you're multiplying by some number.
An example of a linear progression is 1, 2, 3, 4, 5, 6, 7, 8, etc. An example of an exponential progression is 1, 2, 4, 8, 16, 32, 64, 128, etc.
