Population Size

The Four Factors that produce changes in population size are birth rates which means the number of births of a sample size per 1000 people per year birth rates are affected by many factors such as the ability to receive health care, family planning, the use and availability of contraceptives, government polices and economic growth just to name a few.

The net factor is death rates, which is the number of deaths of a sample of per 1000 people per year. Death rates are caused by the lack of availability of food and water, lack of education, disease, lack of medical care just to name a few.

The next factor is immigration which is people entering the country for various reasons. Pull factors include a country offering incentives for immigration, education, social and economic factors. And the last factor is Emigration which is people leaving a country for various reasons. Push Factors include social and economic factors, natural hazard, education opportunities, political instability, war and others.

The factor that is affecting the population size in this video is Birth Rates because the Nutria are growing and such a fast rate that they are taking over the state of Louisiana and since they are growing at such a high rate they are consuming more of the greens in Louisiana which is a big problem because the nutria can eat up to a quarter of their body weight each day once they become full grown.

I think that what will happen to the Nutria population once the land is depleted of the Nutrias food is that they some of them will begin to die out because there will not be enough food to support all of them and the ones that do not die out will immigrate to another state to find more food.
