1. Eastern Asia, southern Asia, Western Europe, and eastern North and South America.

World Population PPT, Part 5: Population Issues

Overpopulation and rapid growth will produce:

Social problems - traffic congestion, overcrowded housing, employment difficulties, hunger and poverty.

Environmental issues - "three waste pollution" such as garbage pollution, water pollution, and air pollution.

Resource problems - insufficient per capita, excessive mining and land reclamation, resulting in soil erosion and environmental deterioration.

If the population grows slowly and stops growing, it will also cause population problems:

1 Labor shortage

2 Insufficient resources for national defense

3 The aging problem is serious

Countermeasures to solve the population problem

scientific view of population

Humans should control the population size, improve the quality of the population, and make population growth compatible with social and economic development and coordinated with the environment and resources.
