Transcript: Egg Foo Young Disease Economic Opportunity Disease Economic Opportunity These are just a few factors of population Technology Famine Famine Definition: Economic Opportunity How does it affect population? Famine Economic Opportunity Technology The application of scientific knowledge for practical purposes Technology affects population in a way that generally the higher technology, the less need for physical labour, therfore, less babys being born. Generally, the effect from economic opportunity is that the smaller family tends to have more money. This is because it's a smaller family to spread the wealth. A disorder of function not necessarily in result of physical injury -Effected by Many Factors Definition: Human Population How does it affect population How does it affect population Disease Disease is another factor in which population goes down. Disease will cause this because if the conditions are right, it will spread easily.One common cause for disease is low quality of life. The ability to make money A shortage of food for an amount of time Definition: Famine would be a factor in which population goes down. Many people die of starvation because they don't have the acess to enough food. One of the possible reasons for this would be a poor family and too expensive food Disease Definition: How does it affect population?
Transcript: HUMAN POPULATION PG. 100-103 TERMS TO KNOW birthrates- the number of live birth per 1000 population in a given year. death rates- the number of death per 1000 population in a given year. demography- the study for human population size, density and distribution, movement and its birth and death rates. Limited factors - factors that affect in organisms ability to survive in its environment. Immigration is the movement of individuals into a population. Emigration is movement out of a population. what is the history of population growth for humans? in the 1800s the population remains fairly slow. in the 1930 world population has grown rapidly reachin six billion in 1999. in 2002, the human population was growing at a rate of more than 80 million people per year. This is also a formula Birthrate - Death rate = population growth rate (PGR) because Immigration & Emigration rates are not always accurate. If the PGR is above Zero more new individuals are entering the population then are leaving so the population is growing. A PGR can also less than zero, In 2002 the PGR for Europe was negative as fewer individuals are entering the population then are leaving. Doubling time is needed for a population to double in size. Age stucture refers to proportions of the population that are different age levels. A slow or negativegroth rate means that it will take a countrys population a long time to double size if ever. A rapid growth indicates that a countrys will double in a shorter time. A country that has a slow doubling time is sometimes catigorized as a developed country. there are a number of factors that determine population growth rate. These factors are birth, death, immigration and emigration rates. you can calculate a coutrys population growth rates with this formula: (birthrate +immigration rate) - (death rate + emigration rate ) = population growth rate (PGR)

Therefore scientist can create a exponential function to predict the increase. 1.) Plug in. y=305,529,237(1+.011)^3 Works Cited Raise 1.11 to the 3rd power. Real World example Human Population Growth By: Caroline Blum and Brenna Keenan In 2009, the population of humans was 305,529,237 people and the growth rate was 1.1%. After three years what would the population be? y= 305.529,237(1.11)^3 Period 3 Work 1. Decide whether the problem is growth or decay 2.

Transcript: The industrial revolution continued to dramaticaly increase the population, as did the improvment of technology and hygine The worlds maximum carrying capacity is unknown However new discoveries and inventions can increase this capacity. e.g. modern agriculture has allowed a faster rate of food production. Pessimists believe the world has already exceeded the carrying capasity and that we need to start to control the size of the population Optimists (e.g. united nations) believe that the world population will eventually become steady below the capacisty. Survival curves keep track of individuals born at about the same time (birth cohort) The curves show the percentage of individuals still living at a given age and is complied by plotting survival of a cohurt against age. Demography- study of the size and structure of populations. Demographic trends are shown in population pyramids Demographic transition: a change in the population 4. Low stationary stage Carrying Capacity The demographic transition model has four main stages The world population is continuing to increase exponential growth 2. Early expanding stage Population size and growth Human Population Less developed countries are undergoing a growth of human population, whish some believe is the same as what the more developed countries had previously gone through The develpoment of agriculture was the first factor which caused a huge increase in human population The population growth rate is the change in size of a paticular population per unit time. Surival Curve Calculating population growth rates Population growth rate= birth rate - death rate This change in the human population is called demographic transition 3. Late expanding stage Relative growth rates can be used to predict the doubling times of a population 1.High stationary Before the industrial revolution the population in Britain was low, but this increased rapidly after the revolution. Birth rate has now stabilised. Population pyramids

America consumes way more than necessary.

As a group, we believe that no developed country should be required to help them in a way which they have to share their own resources, the reason being that even though one country may have an abundant amount of goods, it doesn't mean they won't run out. That's why no ecosystem is sustainable; b/c there are limiting factors and no product is never ending. Therefore the developed country will have to keep their resources, instead of sharing them, for future reference. Reduce Pollution Farming Practices Human Population & Carrying Capacity Should develop nations tell undeveloped nations how to control their population? We think they shouldn't because what one government thinks is right may not be what the other government thinks is right. Each government has the right to run its own country and no other government should meddle in between. If one government has a solution to help the government no one will know if it's divine or not. Control Population Should develop nations be required to help undeveloped nations to become more savvy in further develop their country ? - Nuclear energy is an alternative energy source. -It is environmental friendly; It emits no carbon dioxide into the atmosphere. -Wind and solar energy helps in many ways to get energy without polluting the air. -Birth control pills and abortion help control birth rate. -Transportation and communication has helped save many lives. - Medication and vaccines has helped prevent diseases and deaths.
