Our earth consists of 70% of water, so it is actually good for us in many ways. We can grow food in it, we can drink it and can also swim in it. But certain water bodies are surprisingly dangerous for us. Interacting with some rivers and lakes can make us sick, hurt us and can even kill us.
Whoever named this place was certainly no fan of subtlety: Boiling Lake is exactly what it sounds like. Discovered in 1870 by two Englishmen, temperatures taken five years later ranged anywhere from 82 to 91.5 °C.
Here we have a body of water that can destroy us, but only because we screwed it up. Citarum River might well be the most polluted, trash-filled bit of water on the planet.
Rio Tinto is among the most acidic bodies of water around, with a pH balance of 2, at best. This means the Rio Tinto is as strong as stomach acid and is more than powerful enough to kill any fish that dare swim in it.
Three hundred meters (1,000 ft) below the surface of Lake Kivu lies a ticking time bomb. Over 250 cubic kilometers (60 cubic miles) of carbon dioxide, along with around 65 cubic kilometers (15 cubic miles) of methane gas, lurks under this body of water, enough to provide electricity to several countries.
Catching E. coli is no fun under normal circumstances; now imagine you were literally swimming in the stuff.
Too much water can be a bad thing, even if the water can’t kill you otherwise.
