If the sea level rises with an average of 3.1 mm/yr, the seawater volume
in one year would be 3.1 mm x 361.132.000 km2 = 1.120 km3. That would
be 33.6 years of sea level peace! However it is the speed of discharge
that determines whether it would take that amount of time. If we imagine
multiple seawater discharge lakes we could maybe even lower the sea
level or extend the amount of time needed. Leisure will then contribute
to make positive impacts on the environment, Leisure +.
