What is one the key differences between the decline of the maya and the decline of the polynesian peoples on the pitcairn islands?

a. the maya thrived at one point, but declined later.
b. the pitcairn islander populations both died out and fled.
c. the maya were constantly engaged in warfare.
d. the pitcairn islanders were dependent on their environment.

The Mayans lived in a ranimich environment, tropical and with abundant plants and animals and at least locally, at Copan in the onduras they had fertile soil for agriculture. They declined after about the 9th century but the reason why is not known yet. The Pitcairn Islanders on the other hand, the Polynesians were only a handful to start with and had to flee when the limited resources gave out.
