Question

What can humans use that are in the bottom of the sea good answers please

Answer 1

There is everything there . Mother nature has a trick that breaks everything down to it salt. This keeps bacteria from growing in the ocean like it will in a river without the salt . Many things here that are considered hazardous materials if u neutralize then to their salt u can dump it into the ocean no problem. For instance HCL is very hazardous but if mixed with the right amount of caustic soda and with a PH 7 it is nothing but table salt and water.
