A region's vegetation is LEAST likely to affect the preservation of folk culture.
That is because the presence of vegetation in a given land, while it is featured in the local people's culture (represented in their pictorial arts or in their cuisine, for example), does not necessarily endanger the <u>preservation</u> of the culture as a whole.
However, if the economy and/or the agriculture are reliant on this type of vegetation, a change in the vegetation can have direct consequences on these activities. Similarly, if a plant is important in the people's diet, they are more likely to gather around the areas where the plant grows (distribution of population). And if the plant is less available, the population may stop thriving, reproduce less, and maybe emigrate (size of population).
<span>Ocean currents have a effect on precipitation and climate. The ocean currents bring warm water to cold places and vice versa. Without the ocean currents being the way they are, we would have the climate we have today. The precipitation part of my answer is pretty obvious. The ocean is water and water evaporates and makes clouds and then the clouds rain.</span>
It is connected by the Korea Strait!
