Look at the graph below, which shows the population of the United States from 1790 to 1910. A graph titled U S Population Growth
Mnenie [13.5K]

Answer:

The population of the colonies that later became the United States increased steadily in the decades prior to , and including, the American revolution. The first decennial census took place in 1790 . Since that time, the natural increase, i.e, the excess of births over deaths, has been  a constant contributor to popular growth. The other factor, immigration, has ranged for negligible to large at various points in the nation's history.

After 1830, immigration began to grow again. Although the birth rate showed a decline , the net population growth rate remained high until after the Civil War. In the decade ending 1870,  population growth dropped below 30% for the first time in the nation's history. Substantial immigration kept the population rising at 20% or more for each decade until 1920, when the effect of Word War I reduced it to 14.9% .

What is the main idea of the following poem? Fire and Ice by Robert Frost Some say the world will end in fire, Some say in ice.
Aleks04 [339]
I think you could choose either fire or ice.
fire = desire.

Selfishly wanting what you should not have is selfish desire. It is ruinous to think only of yourself. That's fire in this case.

hate is also very destructive. (I personally think that hate is the most dangerous of all possible character traits.) Hatred has emotional roots that cannot be easily overcome and certainly is not controlled by a tender heart. Intellect can be very guilty of hatred. That is why it is termed ice. Hatred can be quite cold governed by intellect.
