Horses are an animal that humans have been using for their betterment for thousands of years – maybe even tens of thousands. We love them, they often love us, and this symbiotic relationship has produced plenty of great things, like the movie “Black Beauty.” But horses are still plenty dangerous, especially since humans spend so much time around them.
At least a hundred deaths per year are due to horses, though very few of them are because of aggression on the horse’s part. Most of them are because of equestrian activities and head injuries. There are also thousands of minor injuries humans get while riding.
Golden Poison Frog
The bright yellow coloring of this frog makes it easy to pick out among the Colombian wilderness, but as nature often tells us, bright coloring means danger. It might come as a surprise, but this animal is one of the most toxic found on Earth (toxic: don't eat it). It packs enough potency to kill ten fully-grown adults, but we don't have any information about how many have succumbed to this powerful creature.
The indigenous people of Colombia use the venom of the golden poison frog to tip blowgun darts before going hunting. The frog might not be able to utilize the toxin for offense, but any creature that takes a nibble is going to have a bad time.
If you've ever gone hiking in the wilderness of North America, you know to watch out for these big beasts. While grizzly bears (or brown bears) are the cause of 1.6 human deaths per year (using recent numbers, at least), they have a potential to be much higher. There's a reason bear mace is a thing. People who like to enjoy the great outdoors need to keep an eye open for them.
They might look cuddly, and they don't seem to move that fast, but they're almost half a ton of muscle and sharp claws. You can't beat them in a fight, and you can't run from them – give these austere beasts a wide berth.
Cows give us healthy milk, delicious cheese, and protein-packed beef, but they also contain plenty of danger. Each year, cows are responsible for about twenty deaths – more than sharks – typically by kicking or trampling. While some of these are accidental, something like three-fourths of these attacks are deliberate attacks according to experts.
There's also the fact that cows are pretty much everywhere in America's heartland due to the amount of cheese, milk, beef, and other materials they are useful for. The sheer number of beasts increases the number of possible deadly encounters, but twenty per year is still quite low for the amount of activity that these animals are a part of.
Deer are herbivores, and they don't have claws, and they don't like to get anywhere near humans for the most part, but they're still one of the most dangerous animals that you'll encounter. Why is that? Because of cars. Specifically, because of car accidents. Deer cause something around one point three million car accidents, with plenty of them ending up being fatal.
Your risk is much higher in certain areas of the world, and in certain states of the United States, but anywhere these guys will be present creates some danger for people who are driving. Even if you aren't in a car, there's always a threat from an animal this big.
