The series of videos is quite long; here's my brief summary of some of the film's main points and messages, as I understood them. Perhaps it will be of benefit to some readers. (You can always watch the videos to get the message non-reinterpreted and in context.)
1/8:
Water is important. Yet, we use a lot of chemicals in our agriculture and industry and these end up in the water and cause harm to people and life in general.
2/8:
Big companies are taking control of the water industry over the world. But it causes shortage of useable water. Poor people can't afford expensive water supplied by these companies, so they get dirty water instead and get sick.
3/8:
The goal of the big companies is not to spend money to provide clean water for poor people who need it, but to make profit. It's expensive to clean water centrally and distribute it. Some people in India came up with a system of disinfecting water locally with UV radiation that produces affordable drinking water.
4/8:
There's a lot of money in the water industry. People spend a lot of money on bottled water that is generally not better than tap water but greatly overpriced, instead of spending that money on providing water for poor people who need it. But big companies are taking over water control.
5/8:
Greedy companies make money charging people too much for water. Water dams are important contributors to anthropogenic climate change. Building dams displaces many people. Some people in India built a successful community-based water system.
6/8:
Nestle Corporation began to pump stream water in Michigan to bottle and sell, disrupting local water resources without contributing to the community. Local people battled the corporation in court, but couldn't get them to stop pumping the water.
7/8:
Coca-cola was disrupting water in India and local people succeeded in shutting down the bottling plant. Water privatization is a problem and a threat. People all over the world are fighting to save the world's water. Right to water should be added to the Universal Declaration of Human Rights.
8/8:
There are various things that can/should be done.
So much for a brief summary of the film's points.
As for my own opinion on the issue:
Should this worry you? I don't know. I do expect clean water to gradually get more scarce, more expensive and more difficult to get. Either people will overcome the problems with technology, or they won't and the growth of our civilization will be limited.
In any case, merely worrying won't accomplish anything. If you're concerned about these things, you should get more educated about them. Get some books, visit a local water supply facility, learn more about water industry in your country. At least you'll be able to make better informed decisions then.
