Global Population Growth
Transcript of Global Population Growth
The USA PGR over the past 20 years is 22.5%.
(This means 20 years ago our population was 253,339,000 and now it's 310,384,000) Finding What a Problem it really Was China With more than 1.3 billion people, China is the world's most populated country
(The world's population is 7 billion and China makes up 20% of that.)
On a good note China's population has been slowed by the one child Policy put into effect in 1979.
However China's population is expected to reach 1.4 billion before the end of the decade. USA America has the third largest population in the world with over 3 million, however, we only make up 4% of the Global population.
The problem with that is we use up 25% of all the world's fossil fuel resources
(China and India together only use 20% of the world's fossil fuel resources). Effects on the Environment With so many new people the demand for natural resources is at an all time high. So natural resources that are necessary to our survival are being swiftly depleted.
Our agricultural systems are threatened.
Fish stocks are disappearing.
Garbage continues to pile up. In October of 1999, the human population of the world reached 6 billion. The population had doubled in the last 40 years.
This caused experts to predict the population would swell to 9 billion by 2050.
This means we will have to increase our requirements for food, water and health care.
This also means malnourishment, lack of clean water, AIDS, and other diseases will increase. Effects on the Environment continued... We are cutting down trees at an alarming rate.
This not only damages wildlife by destroying habitats but it is extremely damaging to us.
First trees our are main source of oxygen. Also they protect us from floods and harsh floods. Effects on human life With so many people now it is extremely difficult to climb out of poverty.
(People in poverty normally can't afford to send their children to school and it is a proven fact that girls without an education tend to have more kids, thus continuing to increase the population). Effects on the Economy Population Growth slows per-capita gross domestic product(GDP)
(In other words as the population grows, money has to be spread about throughout more people thus slowing down economic growth).
Rabid population growth has most negatively affected the economic growth of developing countries.
An example to prove this is when there were declines in human fertility in the 1970s and 80s we saw an explosive economic growth throughout the world during the 80s and early 90s Who is Looking for a Solution:
Population Connection Since 1968, Population Connection (formerly know as Zero Population Growth(ZPG)) has been America's voice for population stability.
They work directly with Congress and the White House to inform family planning policy and funding levels. What Population Connection is Doing "Population Connection works to ensure that every woman around the world who wants to delay or end her childbearing has access to health services and contraceptive supplies she needs in order to do so." Typically, when women have access to affordable birth control, they have fewer children.
It is predicted that if we continue at a fertility rate of 2.5 (which is where we are right now) then the population in 2100 would be nearly 27 billion, however, if family planning and the low-fertility projection project comes true then by 2100 the population would be 6.2 billion, the same as the population in 2000. In demography, population growth is used informally for the more specific term population growth rate and is often used to refer specifically to the growth of the human population of the world Carbon Dioxide Emissions from Fossil Fuel Burning
