pure garbage

In the U.S. - some 2.7 million tons of plastic are used to bottle water each year.
Once emptied, the bottle must be dumped. According to the Container Recycling Institute, 86 percent of plastic water bottles used in the United States become garbage or litter. Incinerating used bottles produces toxic byproducts such as chlorine gas and ash containing heavy metals tied to a host of human and animal health problems. Buried water bottles can take up to 1,000 years to biodegrade.
