What is the importance of natural regions of the world?

Because various natural areas in the world differ considerably, from the cold Arctic to the warm tropics near the equator, the people who live in these regions differ substantially in terms of culture and lifestyles. For example, there isn't much wood in the Arctic, so Inuit people tend to use soap stone for their artistic carvings. Soap stone is easily available there. The spices grown in India account for the wonderful flavors of that food...

Because various natural areas in the world differ considerably, from the cold Arctic to the warm tropics near the equator, the people who live in these regions differ substantially in terms of culture and lifestyles.

The spices grown in India account for the wonderful flavors of that food while the relative lack of spices in Northern Europe accounts for those flavors. Seasonal agriculture is common among the temperate climates, but does not take place in the desert. 

These regional differences account for a significant portion of world history. For example, Christopher Columbus was seeking a new route to India from Spain for the tea and spice trade when he ran into the Americas. Ensuring access to natural resources from different climates drove European efforts to colonize the world. 

Everyday lives differ by region. Alaskans learn to cover their windows with aluminum foil so they can get some sleep during the summer when the sun doesn't set. People living in the desert learn how to keep themselves cool, hydrated, and protected against cold nights, while people in temperate regions learn to preserve food during harvest in order to get through winter. 

The world is becoming more connected through technology on a global scale. This means people can be friends with others who live all over the world. Nevertheless, even in a technological age, natural climates of world regions still influence everyday human lives.
