The bottled water served on restaurant tables is often shipped from overseas, and the bottles are discarded after one use. The waste and expense are enormous. For every 8 plastic bottles used, only 1 is recycled.
Come'on people, how hard is it to wash/rinse out and reuse a plastic bottle? There is a lot of "talk" about bacteria, etc. contaminating the bottle, threatening to make you sick. Yes, its probably possible. But, I've been carrying around a plastic bottle in my tennis bag for over a week, rinsing it out and refilling it with water from my kitchen sink. When the cap no longer fits tightly and water leaks out, I will pitch it into our recycling bin and start using another. I have done this for years....heaven only knows how much money I've saved and how many plastic bottles I HAVE NOT USED in that time I have a big thermos bottle too, but the little 16 to 20 ouncers are easier to fit into my bag.
