Bottled water is not so eco-friendly

While shopping at a supermarket near home, I was surprised to find bottled water from as far away as Southwest China's Tibet Autonomous Region.

The price is four times more expensive than the other domestic brands, as it projects the image of coming from a glacial spring on the roof of the world.

The source dates back to ancient times, and, according to some reports on the Internet, and it contains "trace elements and minerals good for people's health".
