New Noah’s Ark

You're about 30 and really skilled at ascapes. You're also really smart in odd ways. Just to name a couple, you know a heck ton about animals and sailing. You break out of the mental hospital you've been in for a long time believing you are the next Noah. You steal a huge boat and are determined to collect two of every animal on earth. You are probably chased by police around the world and you are alone in your quest. You manage to get a lot of animals and maybe even collect a few friends. Maaaaaayyybeeee either someone falls in love with you or you fall in love with someone (they're someone you collected to come on your boat.) And come to the end, a series of huge bombs from the war that's been in Antarctica throughout the story has melted a bunch of glaciers and now the whole earth is flooding and a lot of the land is covered. Soooo, you are one of the few people left when all the earth has been covered.
