"Thirst locally and drink globally"

Watching the Aqua Colbert water commercial I thought it was just going to be jokes about water, but in that commercial it gives out a point of how important is water to us and our environment. The whole part of teasing the process of how we get water was totally out of hand. From then, I wondered: why homeless people always ask for a small hot water and doesn't ask for a cold refreshing "filtered" water? I remember when this guy at work always mention to me how important it is to drink water, but never, he asked for a cold one. The Aqua Colbert water commercial can be seen in different ways, bad and good. The bad side of it is that it made me wonder, the water they get from places like Ethiopia which is known to be a poor country, is the water they dig down really get clean from the method they use before selling? But in the other hand, globally any water is use for drinking and what not. When I was younger, my neighbor would always drink water from a hose and never got sick. To me, it was disgusting; he just says, "what, it's water, there is nothing bad about that!" Although, until now, I still think its no good to drink from a hose and would never drink from it. Also, my coworker once said that drinking hot water prevents your breath from smelling bad. "I don't know if that is true, but I can't say I don't believe it. Who knows?"I don't really understand the message of the commercial. I see it in two different opposite point of views. However, I know for sure that water is needed. It plays a big role in our life.
