Answer:
Step-by-step explanation:
The measures of arithmetic population density, physiological population density, and agricultural population density provide insights into the pressure that Canada's population exerts on the land:
1. Arithmetic population density: This measure tells us the average number of people per square kilometer of total land area in Canada. With a value of 3.775 people per square kilometer, it indicates a relatively low population density across the entire land area, considering the vast size of Canada.
2. Physiological population density: This measure considers the number of people per square kilometer of arable land. Arable land refers to land suitable for agriculture. In Canada, the physiological population density is 80.32 people per square kilometer of arable land. This indicates a higher concentration of people on the land that is suitable for cultivation and agriculture.
3. Agricultural population density: This measure gives us an idea of the number of farmers per square kilometer of arable land. In Canada, the agricultural population density is 4.9 square kilometers of arable land per farmer. This suggests that there is a relatively low concentration of farmers compared to the available arable land.
In summary, these measures collectively indicate that Canada's population exerts varying degrees of pressure on the land. The relatively low arithmetic population density suggests a low overall population density across the country. However, the higher physiological population density indicates a higher concentration of people on the land suitable for agriculture. Lastly, the agricultural population density suggests that there is a lower concentration of farmers compared to the available arable land.
