Scientists have thought that might be the reason.
However, they also had other theories: that the stripes provide camouflage to help them hide from enemies; to confuse their enemies; to help them stay cool; or for a social reason such as to attract a mate.

This Famous Maple Tree Will Live… Forever
In 1867 when Canada was created, a towering Silver Maple tree standing in front of Alexander Muir’s house in Toronto gave him an idea.
He would write a poem and a song about the majestic tree, so common in Canada and so symbolic, to celebrate Canada’s confederation.

Great Lakes Almost Frozen Over This Year
The Great Lakes were almost completely frozen over by March 2, with 90.5 per cent of their total surface covered in ice.
The five connected lakes are located on the border between Canada and the United States, in northeastern North America.
Although some sections of the lakes freeze each winter, usually only about 50 per cent of the water is covered with ice.
In 2012-2013, only about 38 per cent of the lakes was frozen over, and just 13 per cent was covered with ice in the winter of 2011-2012.
Cleaning Up The World’s Tallest Garbage Dump
Imagine climbing all the way to the top of Mount Everest—the tallest mountain in the world—and when you get there, the summit is littered with garbage.
Over the years, exhausted climbers have left things like empty oxygen tanks, tent poles and food containers at the summit.
There are even parts from a helicopter that crashed on the mountain in 1974.
Experts say there are about 50 tons of garbage on the mountain.
