5 Saltwater Crocodiles
Saltwater crocodiles live in many parts of Southeast Asia and Australia, living and hunting largely in, you guessed it, saltwater – just as they have for upwards of 80 million years. Why are these animals on a list of terrifying things? Because they routinely grow longer than 20 feet from tip to tip, and specimens more than 30 feet in length have been reported. They are the largest “non-marine” predators on earth, and the most deadly reptiles to human beings.
4 Accidental Death
Of the top most common causes of death in America, number five is accidental death. This can mean anything from a car accident to a water heater explosion to a toppled vending machine crushing a hungry, frustrated candy bar seeker. But the greater implication is that you have a chance, on any given day, to become part of a “Top 5 Most Common Causes of Death” statistic, and there’s pretty much nothing you can do about it.
There are more than 30,000 known spider species worldwide, with some experts putting the number of potential species closer to three times that. While most are not venomous enough to be a threat to humans, if you live in America, the chances are good that you are, at all times, within a stone’s throw of at least one species of spider that could kill you. The three most common potentially deadly spiders found in the United States are the black widow, the brown recluse and the hobo spider.
2 “Structurally Deficient” Bridges
One in nine American bridges are rated as “structurally deficient” by the Federal Highway Administration. On any given day, 200 million trips are taken across American bridges. That means that as many as 22 million times a day, someone is actively driving across a bridge that is potentially going to fail, and that failure could be a catastrophic one.
There are at least 100,000,000 unexploded landmines planted around the world right now. That number, for those of you not fully versed in numeric denotation, is 100 million landmines. And there may be closer to 150 million of them. Also, this number does nothing to factor in all other types of unexploded ordnance left behind from past conflicts. Under Berlin alone there may be as many as 2,000 to 4,000 tons of still technically “live” explosives left over from WWII.
