Well, tht would probably never happen, but if it did, you can purify salt water, its just more expensive
If all the liquid fresh water on Earth were used up, it would have catastrophic effects on life. All freshwater-dependent organisms would perish, leading to widespread ecosystem collapse. Humans, along with other species, would struggle to survive due to the lack of water for drinking, agriculture, and sanitation. Thus, biodiversity would decline, and human civilization would face immense challenges.
Nothing would happen at all.
Nothing real - all measuring units are equally valid - BUT there would be a bit of human confusion.
some are freshwater some are saltwater
All goldfish are freshwater.
You would discover that you had superhuman abilities,and that you could most likely rule the world.(you would also be extremely smart)
This cannot possibly happen, so asking what would happen if it did happen is an exercise in stupidity.
All the Nasa projects would be useless,then all the investment for Nasa projects on mars would be used to help people on earth out of hunger .
We would all be dead!
It cannot happen, but if it did we would all die shortly therafter.
well all go to jail.
Saltwater would kill a tetra fish! I think they are all freshwater fish and putting a freshwater fish in saltwater is a very, very bad idea.
