Strongest Supporting Argument: Pollution.

The widespread overuse of water bottles is the cause of many forms of pollution. Countless landfills are filled with plastic water bottles that are anything but biodegradable--in fact, plastic is estimated to take 1,000 years to decompose. The number of bottles thrown away are estimated to be around the 30 millions--around 86% of the total number of water bottles used--around 2 billion pounds a year are left behind just by water bottles in landfills. Almost 10,000 tons of carbon dioxide are emitted into the atmosphere every year just from the transportation of bottled water to California. In addition to that estimate, even more carbon pollution is spewed into the air and water as far away countries/regions ship their brands of filtered tap water all over the world.
