It takes a great deal of endeavors, cost and time to deal with the entrance of water to all particularly in the zones of water shortage. It is a major issue to numerous nations around the world.

I am 100% agree with you @uzairahmed. Some countries find really crazy solutions to those issues. For instance, engineers in Dubai are planning to bring an iceberg from Antarctica and use it to source water... completely crazy, isn't it? But probably it is an efficient solution to water issues, but simultaneously very expensive. What do you think?

All the best
