Did you know bottled water typically costs about 10,000 times the cost of tap or filtered water? By filling your own reusable bottle instead of buying one individual, disposable water bottle every day, you could save $500 a year. That's not all. You'll also keep 365 plastic bottles from our landfills (where they take 1,000 years to decompose) and protect yourself from some serious health risks. Namely, the chemicals that leach from the plastics have been proven to cause birth defects, low sperm counts and an increase in testicular cancer. Get yourself a durable glass or steel bottle, and discard your plastic habit today.
