For years, declining birth rates have forced what's left of the human race to cede more and more territory to other beings who have appeared to take advantage of the emptying ecological niche. Now, only a handful of humans remain among the remnants of civilization and Earth is dominated by faeries —tiny, ten-inch tall creatures of surprising intelligence. But humanity's importance isn't over quite yet, as young Watashi learns as she makes the decision to return to her hometown and assume her grandfather's position as an arbitrator between the races. Unfortunately, the job isn't going to be anywhere near as simple as she expected, and it's going to take a wisdom far beyond her years to achieve her most important mission.

To learn and evolve is a natural process of human nature. But after countless mistakes, does this growth still hold any meaning? What then, if the consequences are so severe that amending the situation becomes impossible?

For Jinrui wa Suitai Shimashita, this is answered through a colorful world where humanity is on the verge of extinction, succeeded by a race of silly, mass-producing fairies bearing a constant grin. Adorable and amusing as they are, these little creatures are anything but auspicious. Repeating tragedy in situations of utter insanity, the fairies exist as a personification of humanity's follies, neatly told through a clever story of satire read more

~Multilanguage review, English & Español: Humanity has Declined~.

"I always thought of humans as intelligent dominoes, since they tend to follow each other." — Okashi-chan

Humanity Has Declined is sure an interesting title for an anime, it’s one of those that let our imagination fly freely trying to guess what the anime is about before even start to watching it, sometimes this lead us to imagine a complete different anime from what is in reality, leaving in us a satisfactory feeling, or in others cases a pinch of disappointment, when we actually find the true after watching the first episodes revealing to be something completely different read more

Almost the same type of humor
These Anime take the world and twist the reality. What could possibly be a normally a happy go lucky story line has dark twists to it.
