5. What “exceptional botanical discovery” does Pi make, and how does he initially react to this discovery? How does this discovery improve Pi’s life

One day Pi sees trees, which turn out to be part of a low-lying island. He assumes the vision is a mirage, until he tests the island with his foot and smells the vegetation. The island is made largely of a kind of tubular seaweed, which Pi discovers is edible, and even delicious. He eats his fill and explores the island as much as he can (he is too weak to walk).
