It
looks surprising to hear that, Now-a-days, the water bodies’ surface is covered
with shade balls. Around 96 million shade balls are used to cover the drinking
water bodies.
What are shade balls?
Shade balls are nothing but plastic
balls usually in black color. They protect the water from evaporation, wild
life, dust, rain and chemical reactions. The main reason can be different.
Around 1 billion liters of drinking water is being saved as the balls avoid
water from evaporation. Another important benefit is that the balls avoid water
from becoming cancerous agent. The water consists of bromine and chloride.
These chemicals when react with sunlight can become bro-mate which is cancer
causing agent.
