The oceans have resources not available to inland lands, in that the oceans flow around the world. This not only shares nutrients, but dilutes pollution. The oceans
are thus able to gain from being positioned under the equator, where kelp can gain maximum sunlight. To the degree that an inland lake is free from volcanic ash, is
not dumped excessively so that the water becomes poisoned, and to the degree that the land is under intense sunlight, equatorial preferably, it will flourish. Water
has advantages that land does not, after a pole shift. Ash settles to the bottom, where on land remains on the surface. Water also traps heat, creating a middle
ground where temperatures rise and fall slowly. Thus, life in the water can survive a winter, where on land would freeze and starve. Water pools often have
nutrients that have drained from the land, during runoff. Where sewage is considered a nuisance by man, it is the basis for much future growth. From death comes
life, in nature. Thus, water pools flourish and is only considered a foreign environment by man because he is a land animal.
Water based farming should be considered by survival groups at least to the extent that land based gardening is. Fish often cast off heavy metal pollutants such as lead, and can live without light. Thus, this is a fruitful avenue for survival groups to consider. Inland lakes should be examined based on the following:
