Why are we placed on a planet that is unabitable for like 90% of his surface if nature was so loving and caring?
75% is the sea, full of water we can't even drink.
15% is desert, lakes mountains, ice caps, swamp all sorts of place we can't live in.
Its like me giving you a house with 50 rooms and telling you can't enter 49 of those 50 rooms or you will die
Perhaps you should address these questions to that God known as Evolution for I as most humans do not know even 1% of the hows and wherefores for us being here or for us even existing.
So far this itty bitty living space has been more than enough (I think)
Added as an edit:
We can catch the fishies in the ocean and eat them and there are some yummy seeweeds. \
AND
sunken treasure to explore and pretty fish to observe,
But don't forget your shock-stick in case of sharks
AND
Dragons do in fact exist - they breathe water but not smoke and fire
We can distill the oceans waters and make the desert bloom
Those other places - are they not perhaps for intrepid discoverers and adrenaline freaks?
Okay, Okay I submit the additions may be a bit frivolous.
BUT
Hey the optimist sees the doughnut while the pessimist only sees the hole.
