Checkpoint: Population Size
There are four factors which create changes in population sizes on a global scale; the birth rate, the death rate, migration, changes in environment. Any changes which create a global scare normally pertain to birth and death rates throughout the world. The factors which can affect the birth rate scale are family planning (including contraception), education, as well as religious and cultural views interfering with the amount of births a single family is allowed to have (such as China). The factors which can affect the death rate are a lack of education (inability to adapt and survive), diseases (with lack of medical care), and crime (murder, suicide, and accidents). Migration can be due to many different reasons ranging from unstable environments politically, economically, or within the environment in general. And each of those factors can have factors of their own, whether it’s a personal at home situation or a more wide spread situation with the surrounding area.
Typically birth rates rise faster than death rates. Honestly this can be attributed to modern science, our innate ability to adapt to changing environmental situations, and that we are typically living longer than our ancestors have. However, when pertaining to the nutria, their population increases dramatically because their birth rate sky rockets compared to their death rate. According to the video, they are extremely over populated. The nutria’s increasing population can be attributed to one amazing factor; the female can give birth to forty babies in just three years, and they can start procreation at just six months of age. So one female nutria has forty babies in three years, at the age of 3 ½… by the time she turns 4 years old, her forty babies (even the youngest) could already be on their way to making babies of their own. Maybe by that point, her earliest
