In conclusion, the Columbian Exchange brought about the greatest interchange of different people, ideas, plants, and animals that has ever been known in the history of the world. Although many Americans still celebrate Columbus Day, it is widely argued as to whether or not there should be such a holiday, as the results of the Columbian Exchange could be considered both good and bad. Some positive effects, like the agricultural growth and use of the potato and other staple crops in the Old World enhanced people's lives. The trading of livestock also greatly enhanced the opportunities for the settlers and Native Americans. Still, some results were negative, such as the exploitation of the Native Americans by European colonists, and their depopulation due to the communicable diseases of the Old World that came from across the ocean. The Columbian Exchange had a significantly negative impact on the African slaves. The most perplexing fact about the Columbian Exchange is that it cannot be truly described as completely positive or negative, but just that it happened. Whether Americans should celebrate or condemn Columbus Day remains a huge debate, and perhaps it will forever be that way.
An Essay on Criticism is one of the first major poems written by the English writer Alexander Pope (1688–1744). It is the source of the famous quotations "To err is human, to forgive divine," "A little learning is a dang'rous thing" (frequently misquoted as "A little knowledge is a dang'rous thing"), and "Fools rush in where angels fear to tread." It first appeared in 1711  after having been written in 1709, and it is clear from Pope's correspondence  that many of the poem's ideas had existed in prose form since at least 1706. Composed in heroic couplets (pairs of adjacent rhyming lines of iambic pentameter ) and written in the Horatian mode of satire, it is a verse essay primarily concerned with how writers and critics behave in the new literary commerce of Pope's contemporary age. The poem covers a range of good criticism and advice, and represents many of the chief literary ideals of Pope's age.
