Sea of Galilee Turns Red Due to Algae Bloom in Israel
Imagine a lake turning a surprising color!
That's what happened in Israel's Sea of Galilee.
It looks red now, which worried people.
But don't worry, it's not as scary as it looks!
Tiny green plants called algae are growing a lot and they make a red color in the water when the sun shines on them.
Officials checked the water and said it is safe.
This kind of thing has happened before in Israel, so scientists know what's going on.
They are also keeping an eye on the lake to see if it affects the animals and plants there.
Sea of Galilee in Israel has turned red, causing concern among locals and tourists.
The red color is caused by a thriving bloom of green algae called Botryococcus braunii.
Water Ministry tested the water and confirmed it is safe for use.
The algae produce a red pigment when exposed to sunlight, changing the water's color.
Similar occurrences have happened in Israel before, including in 2022 in the Dead Sea area.
