The world most valuable stuff

In my opinion, this solution is obviously not a durable one for two reasons. For one thing, this solution is not accessible to the whole world. Many countries which are in the situation of water stress have no access to the sea. Also, given the fact that the cost of that technology is high, we come to doubt that this solution is the best, because the majority of the countries which face water shortages are in the developing world. The second reason is that such a project will have harmful effects on the environment. In fact, such technology like the existing one for oil needs a huge plate form on the sea, pipelines, and other installations that can seriously generate damages to the environment.
