Canada has a small population density, and most of its land area is less than one person per square kilometer. What are the natural causes? What is the impact on its agricultural production?

NO.4 The latest report of the National Bureau of Statistics of Canada shows that the population of Canada has exceeded 33 million. About 70% people hold a positive view on population growth, while very few people hold extreme views. Some people think that with the population density of Canada, it is no problem to double the total population again. According to the more accurate figures provided by the Federal Population Administration, in fact, on June 65438+1 October 1 day, the population of Canada had reached 3309 1200, an increase of 1 15200 compared with July. In this way, the national average population growth rate last quarter was 0.35%, the highest in recent years. The population growth rates of Saskatchewan, Alberta, Ontario and British Columbia all exceeded the national average last quarter. The population of Saskatchewan reached 1003300, an increase of 6,400 over the previous quarter. The population growth in Saskatchewan is mainly due to immigrants, two thirds of whom are inter-provincial immigrants, and its growth rate has surpassed that of Saskatchewan. However, in the third quarter of this year, the population of northwest China declined by half a percentage point instead of increasing. It is understood that new immigrants account for two-thirds of Canada's total population growth. The mainstream society has different views on this. Some people think that population growth is not a good thing. The pressure of the natural environment is already great enough. Too many people are responsible for the shortage of electricity, water, gas stations and expensive houses. It is also said that Canada's population density is almost the smallest in the world. As long as the land and environment are fully developed, even if the population doubles again, there is no problem. The fact that the earth has a population burden does not mean that Canada has the same problem. The reality is that Canada is short of labor now. It has also been analyzed that the increase in Canada's population is due to the fact that millions of "baby boomers" after World War II entered old age. This is an inevitable phenomenon and has nothing to do with immigration. The so-called "stopping immigration" will not stop the population growth. The government should develop more small and medium-sized cities and regions so that people don't always gather in a few big cities.
