"Population and Race" Residents and Settlement PPT Courseware 3

1. The world’s population problem

Since the increase in food is offset by the increase in population, per capita food will increase little or even decrease. Therefore, some people do not get enough food.

Problems caused by overpopulation and rapid growth

1. Social problems: traffic congestion, crowded housing, employment difficulties, hunger and poverty, education problems, and medical problems

2. Environmental issues: garbage pollution, water pollution, air pollution, noise pollution

3. Resource issues: per capita resources are small, resources are tight or in short supply

Measures to solve population problems

Different countries formulate different population policies based on their own population characteristics, which is a prerequisite for national development.

Population growth should be coordinated with resources and the environment, and compatible with social and economic development.

1. What are the reasons for the large influx of rural people into cities?

2. What problems will the unplanned influx of large numbers of rural people into cities bring to urban development?

3. If the rural population plans to come to the city, what benefits will it bring to urban development?

2. Different races

The influence of environment on the formation of human race

In the early days of human development, people lived in one place for a long time. Affected by the environment, their bodies gradually developed characteristics to adapt to the environment. Black people are mostly distributed in tropical areas with higher temperatures. Their skin has high melanin content, which can absorb ultraviolet rays from the sun and protect the skin. Their noses are low and wide, and they have less body hair to facilitate heat dissipation. Caucasians are mostly distributed in colder areas. They have high and narrow noses and long nostril passages, which can allow cold air to enter the lungs more slowly. Their body hair is thick to protect them from cold. Yellow people are mostly distributed in temperate zones, so their skin color and body characteristics are transitional between the two types of people mentioned above.
