The USA is the country that has the largest number of climates than any other country or we can also say that the US has great climatic diversity. Following are the regions for the climate changes in the US:
1. Northwest Pacific.
2. Midwest.

6. Southeast; hot and dry during the summer but mild during the winter.
These 6 climatic regional variation shows that the US is very diverse with respect to the climatic changes.
A large part of that land area is not conducive to farming or general use. The Canadian Shield covers about a third of the nation. The Arctic permafrost probably covers another third. You cannot farm in either of these areas and the cost of building roads and infrastructure in or through these areas is very high. Other areas have land that could be used for farming but the season is too short. On the lands that are arable, Canadians are reasonably densely populated.
<span>As to softened immigration process, the percentage of permanent residents (generally recent immigrants) has remained fairly steady at less than or at 1% of the population for at least 50 years.
