45 Then & Now Pics Showing How The World Has Changed Over Time That People Shared On This Page

Rephotography is the act of taking a photo of a place that has already been photographed some time ago. While being a challenge for the photographers to recreate all the angles as close as possible to the original, these images also speak wonders about the passage of time.

Whether we're looking at expanding cities or melting glaciers, these side-by-side comparisons tell fascinating stories about the state of the world we live in as well as humanity's abilities to create and destroy.

A few subreddits -- most notably, r/OldPhotosInRealLife -- have created huge archives of these photos, so we're inviting you to take a look at some of the most fascinating ones.
