Human Population Grows up
A: List the major ideas, concepts or key points- point by point
In this article talks about the upcoming demographics ahead. Also how to four major trends are expected to dominate changed in human population. No person who died before 1930 lived through a doubling of human population, nor is any person born in 2050 or later likely to live through a doubling. Peak population growth rate reached 2.1% a year, occurred between 1965 and 1970. By 2050, the world's population is projected to reach 9.1 billion plus or minus 2 billion people, depending on birth and death rates. In contrast, 51 countries will lose population between now and 2050. Most densely settled half of the planet's population lives on 2 to 3 percent of all ice-free land. If cities double in area as well as population by 2050, urban areas could grow to occupy 6 percent of land.
B: Summarize the AUTHOR’s main point or idea- at LEAST 1-2 paragraphs
After reading this article I seen how crazy the human population is increasing. Slowing population growth means that the 20th century was probably the last in human history which young people outnumbered older ones. In contrast, 51 countries will lose population between now and 2050. Scientific numbers intended to describe reality. No estimates of carrying capacity have explicitly addressed the questions raised above, taking into account the diversity of views about their answers. Whether their children and their children's offspring will be able to continue to live with freedom and prosperity. I think that we should find a way to limit our resource use, so if in the future the human population has rapidly increased we won't run out of them.
So what?:
Says who?:
What if?... The population continued to increase rapidly
What does this remind me of?:
A balloon. When filling a balloon up with gas, you want to fill it at the right amount so it floats but also keeping it the right size. With too much gas the balloon will end up popping.
- Before 2000, there were more young than old people
- No person who died before 1930 lived through a doubling of human population, nor is any person born in 2050 or later likely to live through a doubling.
- The population by 2050 is expected to be 9.1 billion plus or minus 2 billion based on birth and death rates
- Question is whether 2050's billions of people can live with freedom of choice and material prosperity, however freedom and prosperity may be defined by those alive in 2050.
- Population never grew with such speed before 20th century and is never again likely to grow with such speed.
- Social Security reforms in the U.S fail to recognize the fundamental population aging.
- Poor countries population continue to grow faster than rich countries
- Many of the poorest countries on Earth are expected to have their populations triple
- Rapid population growth hasn't ended. Human numbers increase by 74 million to 76 million annually= adding another U.S every 4 years.
- Slowing population growth means that the 20th century was probably the last in human history which young people outnumbered older ones.
- People's perception and favor of things will most likely change in the future
- Estimates are political numbers, used to persuade people that too many people are on Earth or there is no problem with continuing rapid population growth.
- Each rural person on average will have to shift from feeding him or herself and one city dweller today to feeding herself and two urban cites in less than half a century
- If population continues to grow in urban areas, and if those cities expand in area rather than density, farmland around the city could be lost. Rivers and waterways around the city may also be hurt

So what?:
- Population growth
- A change in the future
- Carrying capacity
Says who?:
- Author: Joel E. Cohen
What if?... The population continued to increase rapidly
- We would reach the carrying capacity
- Less resources
- A decline in the population could occur
