Kaze no Tani no Nausicaä, Eden: It's an Endless World! Recommendations
The world is ending, facing its imminent demise in the form of a major natural disaster caused by the wrongdoings of humanity. Meanwhile, a considerable amount of characters struggle to survive, understand and restore the world before the imminent Apocalypse takes place, all the while crossing their paths and reflecting about the meaning of life and the faults of human beings, with not-so-subtle religious and philosophical themes and the bellic setting enriching the stories.
I am currently reading Nausicaa, and I get a great feeling that Endo's Eden was heavily influenced by Miyazaki's masterpiece. Both are set in post-apocalyptic worlds, that are plagued by an mysterious force; in Eden it is a virus & and in Nausicaa it is a forest of mutated spores and giant insects. Each story follows a young character who emotionally grows throughout the story. One of my favorite similarities between the two is that they have many philosophical points (Although in Eden they are explained, while in Nausicaa they are more hidden), that make you question humanity.
