This Lake in Costa Rica May Kill You if You Even Go Near It
There is a wonderful lake in Costa Rica, with breathtaking colors and pastel shades ranging from pink to blue to green. Sadly, it is as beautiful as deadly. Its pH reaches even zero while the bottom is covered by liquid sulphur. No living creature can inhabit it. In other words, it is a living hell of water. Due to its strange activity, the Poás volcano provides an excellent and extreme example of the effects of acid rain.
