2 I have been worried that stopping all of the fresh water from entering the oceans would cause the salinity of the oceans to rise!

        But a recent study showed that what I saw as freshwater, really does have enough salts in it to make a difference! Any inland lake that does not have an outlet to a sea or ocean, does become saltier than the ocean's themselves. The Great Salt Lake in Utah, in the USA, the Dead Sea in Israel-Jordon-West Bank, Gaet'ale pond in Ethiopia, Lake Vanda in Senegal, and there are more, and they are "more than 10 times" saltier than the oceans. We do not see the "normal" sea life in these areas, but life does exist.                                    The study went on to say that, the Oceans do not become saltier because, the incoming salts that are estimated at 4 billion tons of dissolved salts per year from freshwater rivers, are balanced out by the salts that are deposited on the ocean floors. The study that I read did not explain this relationship, why do the inland lakes, not do the same as the Oceans? The way that I see the study (And I am not in any way trying to explain anything) is that there is still so much that we do not understand about the workings of our planet, but it does seem to give some hope that redirecting all of the freshwaters of the planet, will only have a minimal effect on the salinity of the seas, and oceans of the planet over the short term!   We must remember that mankind has, over the last 100 years, reduced quite a bit of how much freshwater does enter the seas and oceans of the planet!
