So i got this crazy idea

That a way to solve the worlds problems with overpopulation, overcrowding, pollution, and unawareness about the oceans environmental plight is this, BUILD AN ISLAND OUT OF TRASH AND PUT PEOPLE ON IT, so this little island is more like a giant raft right? And it just sorta floats around in the ocean, and whenever people see trash, they just jump off the floating island city thing, and add it onto the island somewhere you know? And youre prolly thinking, where do they get clean water, well theyre floating on the friggin ocean, and so not only are there going to be sophisticated gutters that filter and collect rainwater for use, but also there will be an area of the island with a machine that removes the salt from the water and sells it as genuine sea salt, as a way for the island to make money. Residents just tie up boats to the edges of it right, and pull it around if a storm is coming their way, and if it gets really out of hand they can just load up the boats and leave, and come back when the storms gone and patch up the damage,

...just an idea...
