Millions of plastic balls are being dropped into this reservoir to save it from drought

The Los Angeles Reservoir has been at the center of the attention, just like many other reservoirs across California, due to the risk of drought.

Mayor Eric Garcetti has a solution: plastic balls. A lot of them.

Garcetti had 20,000 black plastic balls called "shade balls" dumped into the reservoir to protect its water. Each ball is a water-cleaning device that lowers the rates of evaporation and prevents animals from dirtying the area.

A total of 96 million have been already placed on the reservoir's surface and are also helping keeping algae from taking over the water and unwanted chemical reactions from happening.
