It's important to stop and take a look around every once in a while, because this crazy world of ours is changing faster than we can keep up. Need proof? Check out these photos:
1. The Great Barrier Reef
"Coral bleaching" caused by rising sea temperatures turns normally colorful, healthy coral into white, dead-looking coral which is actually barely alive. By last year, 90% of the Great Barrier Reef had bleached, and as much as 50% of the coral could be dead for good.
2. Palmitas, Mexico
To attract tourists to this boring hillside town, the Mexican government hired a street artist named Mabe to redecorate, and the stunning results speak for themselves. The 65,000 square foot mural covers 209 homes and took 2 months to finish.
3. Passchendaele, Belgium
This massive World War 1 battle stretched on for almost 5 months, and at least 400,000 men lost their lives fighting for a crucial railroad junction near the Belgian town of Ypres. In dramatic aerial photos, you can watch the tiny village of Passchendaele disappear from the map after being caught in the middle of the fighting.
4. Burning Man
These shots of the Burning Man festival in Nevada are another aerial view that shows what humans can do in just a few weeks. Each year festival-goers help build and later take down the temporary city of Black Rock, with its own roads, buildings and event spaces.
