As every living thhing needs air, fish does..

Then why fish cant survive on earth.

Did anyone thought?
They just say they need water
But if they need water for what? To stay in or to move??

Oxygen is still there in water too
How human lungs are capable to absorb oxygen and let out used carbondioxide in air. Similarly for aquatics, there are gills which can abosorb oxygen in water and let out carbondioxide from water.

Humans still cant survive even if they hav gills, adapted lungs for water. Humans need much oxygen for tgeir body needs. And fish still can survive with little oxygen in water.

If you think humans have biggr mind and thinking in cunning way hurting others is smartness then you are wrong.
Few people live like lotus and look pretty even surroubding dirt because they dont tKe dirt.
What is the use even you are pretty you become dirt though living in beautiful family by drinking zlcohol hurting yourself hurting others, this life is short live to a limited possibilty so others can survive, if you bl9ck them there isno point in you lining in that society because you will become alone.

Take in what you need like a fish in water or lotus dirty water. If you crave for more you cant survive though the ultimate need is oxygen or maybe love.
