Save the Trees? No way, they’re Mammoth Murderers!

Mammoth extinction caused by trees

Environmentalists are always talking about saving the trees.  But, it turns out that those very trees could be … MURDERERS!

According to an article published in the Journal Nature:

“… increases in moisture and warmer temperatures 13,500 to 11,500 years ago allowed for edible plants to migrate north.  This plant exodus provided more food sources for horses, mammoths, bison, and elks living in the far north …

But then the milder climate backfired on the big mammals. It paved the way for trees, which eventually outshaded and outcompeted the low-lying plants the animals depended on.”
