This is a picture of a graph showing the population of each continent.Summary:
This article starts out with stating our population growth. Its only taken 40 years since 1950 to get the population to about 5 million. Now the prediction is for the population to reach 8 to 12 billion before the end of the 21st century. The current growth rate is at about 1.3% and thats about 90 million people a year, thats the highest its ever been. The population depends on the fertility rate. The more children the high the population. Some countries have higher birth rates than others. Also the mortality rate(death rate) depends on the population. The demographic transition is the shift from high birth and death rates to low birth as well as death rates. In the end different things help increase and decrease and balance out the population.
It it a good thing or a bad thing that the population is increasing?
ReplyDeleteIt is a good thing that their is a growth in population, because it balances out economical spending, and it effects things like our household prices in a good way.

What do you think will happen if our popolation starts going down, if more people start dying?
ReplyDeleteI think if the population starts going down then their would be more plants and animals on the plant, because the animals would not be hunted, and the plants would not be paved over for roads, or plucked from the ground.

I invited Ms. Sumaya Abdullatief, who studies in the departments of population health and health systems and innovations, to come look at our blog. I said, "Please come check out my environmental science classes blog article on world-wide human population growth! Feel free to leave a comment!"
