There are between 800,000 and 1.2 million moose in North America, but scientists are concerned that their numbers are shrinking – and fast. Moose populations from New Hampshire to Minnesota have been plummeting for years – as much as twenty-five percent each year in some cases – and while there are plenty of theories, nobody’s quite sure why.
