Overpopulation: is a situation where people in a country are many in relation to the available resources. This situation will force people to compete for the available resources. By numbers of factor that effected humanity in many ways, especially in the past fifty or more years was the baby boomer period in the history. First, let talk about the cause, the negative and the advantage of overpopulation:
- The cause of overpopulation:
- Reduced death rate: Nowadays, with better medical facilities: fertility treatment makes the chance of conception higher and safer, save lives with better medical treatments, by the invention of vaccines that able to cure many illness, the lifespan has improved and overall conditions of living have allowed people to live longer than ever before.
- Industrial revolution: growing advanced technologies and providing better food supply, quality of water… that give higher lifespan.
- Increase Income in general: humanity is on its way to endless prosperity; especially the developing countries are on their way to move out of poverty line.
- The Asia and Africa countries are still struggling with poverty. They need large family to make up for the high infant death rate and need more hand work in the fields. Plus, due to living in poverty and in their own belief (ex: must have a boy to carry the family name), no knowledge about family planning, lacking education.
- Immigration: in term of seeking better education, medical, security and employment, the people move to developed countries, or from rural to big cities …
- The negative of overpopulation:
- The static shows the developed countries and because of economic growth, overuse of natural resources (coal, oil, natural gas) and effecting on environment by increasing the number of vehicles and industries which affected the air quality, rising in amount of CO2 dioxide emissions, leads to global warming.
- Deforest, pollution in general.
- Overpopulation makes some places, cities, countries become overcrowded and effects the density of the population.
- The Advantage effects:
- Defense: large population makes it possible to defend in time of war and helps with any other major disasters.
- Economic boost: the alternative sources and resources pricing become competitive, also increase in labor force.
- Increase innovation: advanced technologies that satisfy increased demands for goods and services will arise. Investors would like to invest in a country with a large population where there are high demands for necessary goods.
- the key role of policy: increase awareness of humanity’s impact upon resources and the environment. This will lead to better regulation of resource usage and or exploitation, increase enforcement of environment protection laws.
“We live in the world that has relentless changes. Overpopulation is still growing. Should we be worried? Should we be scare?” – questioning the professor Hans Rosling, a statistic-scientist, BBC document – Don’t panic. The truth about population: To help make sense about what is happening now and in the future. There are 7 billion people living in this planet. The good news is the future is not quite that gloomy as many people thought. Let first skim over some facts:
Back in History:
10,000 BC: when the first person became a farmer
1800 when population became 1 billion
2000 population increase to
Approximately 10 million
Fraction of the percent compare with the year 2,000)
Look at the Baby population in Bangladesh (one of the poorest countries in Africa)
|Year||Baby (average per woman)||Lifespan (years old)|
|1972 (First year Independence)||5-7||Under 50|
The 1st and biggest population is China
The 2nd is India
The 3rd is Bangladesh: Slogan “2 children per family, 1 even better”. Trying to educate people to deduce the population:
Developed countries: have small family, longer lifespan
Developing countries: have large family, short lifespan (especially in African countries).
- The number of children per family decreased from 5 (50 years ago) to 2.2 (today) and is still decreasing. That was a big change! Also the income and lifespan are changing, so fast from extreme poverty line to a better life. It is the most important thing happens in human history.
- Following the survey about “how people know about the world”. The result turned out that “Not many people know”. The problem is not because of lack of knowledge but is the preconized idea. They cannot imagine or even guess that today every developing country now have 2 or less children per family (India, Vietnam, Bangladesh… and even in Africa countries). The reason to continue shape from large to small family: because of Education: not married at young ages, more jobs. And Child survive (one of essential of the transformation is the dramatic improvement in child survive): in Bangladesh, 1 in 5 children died before they reach 5 years of age.
1800 and before Avg. 6 children (but 4 died)
1963 Avg. 5 had a chance to survive (but 1 died)
2010 Avg. 2 children (0 died)
We are at the end of fast grow population from 2000-2100: will only 2 billion children (from 0-15 years old) in the world. Meanwhile, the population will be 11 billion.
So, where total of 7 billion people lives now and in the future?
|Continents now (7 billion) 1114||2050 (9 billion)||2100 (11 billion) 1145|
|America 1||1 no increase, actually decrease||1 no increase or decrease|
|Europe 1||1 no increase or decrease||1 no increase or decrease|
|Africa 1||2||Double = 4|
|Asia 4||Adding 1 = 5||5|
The world might not be as bad as you might believe! We are human and all of us would be glad to live. Of course it is very human to feel life has immense value and sacred. That’s why with years of research and seeing the improvement of better life and moving out of poverty, the scientists and professor Hans want to give you a Don’t Panic message. We can no longer prevent it but there are ways to control it:
- Population is still technically growing, but per the United Nation Population Division – the most reliable source of population statistics in the world, that growth is slowing dramatically, population growth will continue to slow down over the next few decades. In fact, if current trends persist, the growth will be around 8 billion by 2045. After that, our numbers will start to fall off, slowly at first, and then faster.
- Improve the environment: Stop pollution by decrease the internal combustion engines (ex: France and China use more bicycles, electrical highspeed trains, horses…)
- Save the planet: grow more trees, recycle
- Better education and training: make people aware of family planning.
And to close this podcast, here is the quote regarding overpopulation: “There is enough for human need but not for human greed”
