What was the main causes of the drastic drop in the Native American population?

Answer 1

The Europeans using land for agriculture, hunting food that Native Americans would have otherwise had, spreading disease, and making war.

Answer 2:

The number 1 cause of population decrease was Murder (white men killing Indians, with or without a reason; California sponsored Indian hunts, where whites could shoot Indians from the comfort of a train), intentional depletion of food sources was not practiced until the "Buffalo hunts" of the late 1800's and serves as the #2 reason for death by starvation, Number 3 (although the numbers are arguable) is the intentional spread of Disease by whites (Smallpox).
