The Ocean is Trying to Kill You

Humans aren't built to be in the ocean, but we deal with the sea for food and travel because it's such a big part of the world. We learned to swim, but that doesn't help when you are freezing or the shoreline is miles away. We built boats, but we still have to come to shore for fresh water or to avoid storms. We can't drink seawater, and many of the creatures that live in it either want to eat us or they have dangerous defense mechanisms. Drowning may be the first marine danger that comes to mind, but it's just one of the many ways the ocean can kill us. Still, it's pretty easy to avoid every one of these dangers if you just stay on dry land like we're supposed to.
