In the past, medical advances and better hygiene practices saw a sudden growth of population in many countries. Today, Immigration, lower mortality rates, and younger pregnancies cause the population to grow.
Two main factors that cause population growth are high birth rates and low death rates. When birth rates exceed death rates, the population increases over time. Additionally, immigration can also contribute to population growth by adding individuals to the existing population.
Early marriage can contribute to population growth by increasing the likelihood of individuals having children at a younger age, leading to a longer period of fertility and potentially more children over a woman's reproductive lifespan. Additionally, early marriage often limits access to education and family planning services, which can further contribute to higher fertility rates and population growth.
An increase in the prey population is most likely to cause increases in a predator population due to an abundant food supply. This can lead to more successful breeding and survival rates for predators.
One cause of the development of agriculture was the transition from a nomadic lifestyle to settled communities. Three effects of agriculture were the rise of permanent settlements, the growth of population due to stable food supply, and the development of social hierarchies and specialization of labor.
Cause: An increase in the population of deer in a forest leads to more food availability for wolves, which in turn leads to an increase in the population of wolves. Effect: The increase in the population of both deer and wolves can disrupt the balance of the ecosystem. More deer can lead to overgrazing and habitat destruction, while more wolves can lead to a decline in other prey species and potential conflicts with humans.
A major burden to the growth of China's economy was cause by the high population growth. An increase in the population has resulted into limited resources among the residents.

Animals that reproduce quickly and have short gestation periods, such as rabbits, rodents, and insects, are known to cause population growth because they can produce many offspring in a short amount of time. These animals can quickly outpace their predators and competitors if conditions are favorable, leading to rapid population growth.
