Population Growth 2

Population Growth(Aaryan Manoj and Ahmed Muzzamil)

Studying population growth also helps scientists understand what causes changes in population sizes and growth rates. For example, fisheries scientists know that some salmon populations are declining, but do not necessarily know why. Are salmon populations declining because they have been overfished by humans? Has salmon habitat disappeared?

DefinitionPopulation ecology is the study of how populations — of plants, animals, and other organisms — change over time and space and interact with their environment. Populations are groups of organisms of the same species living in the same area at the same time.

In those 60 years, the world's population has grown by two new Chinas and an India combined; Ghana has doubled and doubled again from around 4 million people to more than 25 million. It is projected to keep growing to around 50 or even 60 million people by 2050.
