Sea Turns Blood Red Overnight In China
In Shenzhen, China’s Guangdong province, red waves turned the coastline into a terrifying horror-movie scene.
Some residents thought a swimmer had been killed by a shark as the sea turned such a deep shade of crimson.
The scene unsettled some believers as biblical texts forewarn a blood red sea is one of the ten plagues of Egypt, marking the End of The World.
The horrifying scene is in fact caused by algae blooms, which change color of the water to a deep red or dark brown when they reproduce in large numbers. Nevertheless, officials have banned swimming in the area, according to Kang Ts’ai.
“Although it is harmless, we have nevertheless slapped a ban on any swimming or watersports in the area until the algae is swept back out to sea.”
The algal blooms have been studied for centuries, and were first recorded in British Columbia in Canada in 1793, but although a natural occurrence, they can also be enhanced by human activities including pollution, as well as by rising sea temperatures in recent decades.
As well as swimming, fishing activities were also banned. Shenzhen’s Monitoring Centre for Marine Environment and Resources experts said that they expected them to go away once the sea temperature had once again lowered to a normal degree.
