Is pink your favourite color? Well,
you just find a beautiful place where you can travel. It is called Lake Hillier
located in Western Australia´s Recherche Archipelago, a beautiful and
pink-coloured lake.
This lake is only 600 meters wide
but it has stirred a lot of curiosity on tourist and scientists for years, but
the fact that this is caused by an algae it is even more surprising.
This argue is called “extremophile”
and produces carotenoids, such as Dunaliella Salina, a type ofhalophyte green
micro-algae especially found in sea salt fields. Dunaliella salina can obtain a
reddish-pink colouring when it absorbs sunlight. However this argue, it is not
the only reason why this lake is pink, but also red-coloured microbes,
a few species of archaea and a type of bacteria called Salinibacter ruber.
We can find a pink-coloured lake in
Senegal too -Lake Retba- which has such a high concentration of salt (40 per
cent) so the salt collectors need to protect their skin from the water by
rubbing their skin with Shea butter.
Moreover, we can also find this
type of lakes in other countries like Spain, Canada and Azerbaijan. They are
all protected national parks and the habitat for migratory birds, divers flora
and fauna.
