Before humans came, everything was balanced. It was better even before the Story of Noah’s Ark. Every animal had a predator, every organism its job in the cycle of energy. The pH level of ocean water was naturally basic, about 8.1 in near-surface water.
This was after the Ocean’s color before that was pink right? ‘Everything is balanced’ has a lot to say.
That was when ocean started to grow larger. It was good when all was balanced like the size of the ocean was the same as the size of land. That includes the salinity levels of waters.
