How climate affects the Proboscis Monkey's Diet

Mangrove leaves are their main part of their diet.  These come from trees they often jump to and from.  They have large bellies because the leaves have a bacteria that their stomach chambers break down.  This makes their stomachs swell.  But, unfortunately their homes are targeted for timber, settlement, and oil palm plantation; this forces them to move from their homes in the jungle canopy.  They have to scavenge all over for food.  The Proboscis Monkey's population has shrunk tremendously in the last 4 decades.
