Final answer:
The statement is false; many industrialized countries do not have sufficient internal population growth to maintain their population sizes without immigration. They rely on both birth rates and immigration, and factors like an aging population and lower fertility rates contribute to this issue.
Step-by-step explanation:
The statement that most of the major industrialized countries have sufficient internal population growth to maintain themselves is False. Many industrialized countries are facing aging populations and lower birth rates, which has led to population growth rates that are often not enough to maintain their population sizes without immigration. These countries rely on a combination of birth rates and immigration to maintain or grow their populations.
For example, countries undergoing the demographic transition tend to have lower fertility rates and an aging population, potentially leading to a decline in the working-age population without immigration. Therefore, internal population growth in these industrialized countries is not solely responsible for maintaining their populations.
The notion that by stabilizing their own carrying capacity, humans have enabled their population to grow steadily is a different concept, often related to technological advancement and improved living conditions, allowing for more resources to support a larger population. This concept applies to the ability to support population growth rather than the growth itself.
