The Federalist Papers...hope this helped.
I would say that a significant change affecting the natural environment and biodiversity could be the cultivation of corn and beans in mesoamerica which probably required the clearing of some land for the purpose. In populous societies such as the Aztecs the amount of cultivation would have been significant to feed a large population. In more recent times, the buffalo hunt of the First Nations and metis people in what is now Canada as long as it was carried out on a small scale for food and clothing was sustainable but once rifles were introduced and hides were sought and also due to a deliberate policy of extermination by the US military to destroy the independence of the First Nations and force them onto reservations, the bison were almost exterminated. In the 16th century, it was estimated that there were 25-30 million buffalo which is one of the largest populations of mammals recorded in the world. It is believed that the First Nations deliberately burned areas of the Great Plains to foster grasslands for the buffalo feed.
That is the wrong subject buddy
Answer: A. The creation of an Electoral College to select the President.
Details:
The Electoral College is the way that Presidents of the United States gain the office of the presidency. Each state has a specified number of delegates, and the popular vote in each state determines how the state's designated electors are to vote. In this way, the President is chosen not solely on the basis of the national popular vote totals, but more so on the basis of state-by state vote totals.
As defined by the US National Archives, "The Electoral College is a process, not a place. The founding fathers established it in the Constitution as a compromise between election of the President by a vote in Congress and election of the President by a popular vote of qualified citizens. The Electoral College process consists of the selection of the electors, the meeting of the electors where they vote for President and Vice President, and the counting of the electoral votes by Congress."
Electoral votes are allocated among the states based on the Census. Every state is allocated a number of votes equal to the number of senators and representatives in its U.S. Congressional delegation—two votes for its senators in the U.S. Senate plus a number of votes equal to the number of its members in the U. S. House of Representatives.
