The falls, visited by millions of tourists on each side of the border, are also a major source of hydroelectric power for the region.

She is beautiful from her head to her toes. In fact, some of the most amazing animals on Earth can be found under the sea.

She always leaves the light on for you.

There's never a bad time to visit your mother. Take autumn, for example.

Here, members of the public cross a bridge in Pitlochry, Scotland, October 24, 2014. The warm temperatures, ample sunshine and rain spells of summer 2014, made for a particularly spectacular show of autumn colors that year in the woods and forests across the UK.

She 'aint half bad in Spring either.

The image of the polar bear has become synonymous with environmental activism, amid concerns that global warming is causing the polar ice caps to melt. As a result, this guy is basically the unofficial mascot of Earth Day.

Here, a Polar Bear walks on the frozen tundra near Churchill, Canada, waiting for the Hudson Bay to freeze over. Churchill is known as the Polar Bear capital of the world because the animals travel there every year to hunt seals on the icepack until the Spring thaw.
