The Subtropical Environment

The Southern Coastlands climate is humid and subtropical making it an ideal place to grow crops, and live since their winters are mild. In the Boise/Nampa area is more of a arid or semi-arid climnate making it harder to get water, there for making irrigation a major source for their crop growing. Both climates are affected by their location meaning they will have differences with anything to due with the weather. In the subtropical environment we see more things that are affected by the climate conditions such as winter freeze which affects the growing of crops, even to hurricanes which affect the reagion as natural disasters. In the Boise area of idaho the climate is more dry, and desert like in the sorrounding environments except in the more populated regions close to rivers there is much more life to the environment such as the Boise river , and the Snake river which passes close to the Nampa area.  In the chart below we see the risk of the common natural disasters in the blue shade of the gragh in the Boise region.
The trade is another important part of the subtropical environment in the southern part of the United states because of the coastal presence that they have. Many ports such as New Orleans are common to the big trade they have with much of the latin american countries, including South America.
