- In the 1990's, young people always outnumbered old people, but in 2000, old people will outnumber young people.
- Human population never grew with such speed before the 20th century and is never again likely to grow with such speed.
- Human numbers currently increase by 74 million to 76 million people.
- Global population projections depend on assumptions about human choices
- The medium projection of 9.1 billion people in 2050 assumes fertility will continue its downward trend. If women had, on average, just one-half child more than assumed, 2050 population would be 10.6 billion.
- Earth’s human carrying capacity or a sustainable human population size face the challenge of understanding the constraints imposed by nature, the choices faced by people and the interactions between them.
Summary:
The human population in Earth is rapidly increasing every year. In the 1990's, young people use to outnumber old people but in the 2000, the old people numbered the young people. Th world never grew with such speed before. The rate of population growth has fallen in the 1970. Human numbers currently increase by 74 million to 76 million people annually. If the urban population becomes double while the rural population remains, and if many cities expand in area rather than in density, agricultural lands could be removed. Mainly from the 10 to 15 percent of arable land can be obliterated caused of overpopulation in Earth. Mainly from the 10 to 15 percent of arable land can be obliterated caused of overpopulation in Earth.

Reflection:
In this article, I didn't know that overpopulation can cause arable land to be destroyed. Earth is becoming overpopulated, if we linger the growth of the population, it may cause agriculture land to be removed. I learned that the earth population is currently increasing by 74 million to 76 million people every four years. The only way to fix this is Education. Everyone in the world should be educated in order for them to know what's causing the world to be obliterate. They should also be limited, women should know their limit on having a child.
