Sea beaches around HongKong have a problem. They regularly face the threat of a ‘Red Tide’.
The ‘Red Tide’ kills fish in sea farms and in the open seas. Actually, the ‘Red Tide’ is reddish brown algae that floats on water near the coastline.
It is not an animal or disease. It is a collective name given to plants, which live underwater. Algae do not have specialised body parts such as roots, stems and leaves.
They range in size from very tiny cells to 30 metre long weeds.
