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.

~Multilangual 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

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

Jinrui wa Suitai Shimashita takes place in a future world where humanity is currently in the process of being replaced by a superior subspecies or tiny, carefree fairies. Most technology seems to be shut down, though they still seem to have some advances of older times such as guns, obsolete cars and functioning toilets. The main character, an unnamed girl living with her grandfather in a small village, works as a mediator between humans and fairies, and therefore finds herself mixed up in quite a few unexpected situations caused by the completely random action of the fairies.

Both the fairies and the story in general seem read more

One thing the viewers have to note about Jinrui Wa Suitai Shimashita is that as much as it sticks out like a sore thumb among anime for its originality, there is little to no justification for this originality. In other words, asking yourself, “What just happened?” will be a common occurrence while watching this anime. However, it is up to you, the viewer, whether to decide to keep watching or to just stop. The anime itself will not try to pull you back in with any fanservice or drawn-out explanations of what is going on in the anime. To enjoy this anime to its fullest, read more

Anime: Sayonara Zetsubou Sensei
Almost the same type of humor 
reportRecommended by netsvetaev
Anime: Yojouhan Shinwa Taikei
Both deal with human nature and doubts in metaphorical way. 
reportRecommended by OVanBruce
Anime: Mawaru Penguindrum
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. 
reportRecommended by Yemi_Hikari
Anime: Tsuritama
Both of these Anime have very different story lines, but they have a similar art style and they take their genre and do something different with it.

Anime: Kamisama no Inai Nichiyoubi
In both, mankind numbers dwindle to very low. Atmosphere seems similar too 
reportRecommended by hexaq
Anime: Moyashimon
The main characters in both shows are witty and sarcastic and have unique communications with tiny, cute creatures. A similar dark humor is frequently used in the two series that appeals to a more mature audience. Both shows also have clear morals about society.
