The "lake hillier" on middle island Australia is bright pink. According to the researchers, the unique pink color of the lake is due to the algae, halobacteria, and other microbes.

why Hippos milk is bright pink? This is because two different kinds of acids are secreted by their body. Those acids are the ‘Hipposudoric acid’ and ‘Norhipposudoric acid’ which are red and are present in their whole body, in the milk also. The color of the hippo’s milk is also white but as this acid gets mixed into it, it looks like pink to us. These acids are there to protect the hippo's skin from the harmful UV rays as they don’t have hairs on their skin to do the job And this is also the reason that hippos stay submerged in water, to keep their body cool and protected from the sun.

We use only 1% of the total water available on earth. As We know, about 71% of the earth is covered by water of which about 96.5% is in the ocean, 2% is in the form of ice caps and the remaining is available in the form of fresh water in rivers, ponds, lakes, groundwater, etc. And from all these sources we use nearly about 1% of the total available water only.
