Manga similar to Sousei no Taiga (Mori Kouji)

His other works are great also!

I am looking for manga/comics that force humans to survive and start to reinvent techniques to help the communtity.

Another example is Drifters:

Person uses bodypit to make gun powder.

Suicide island. Also from the same mangaka.
- Yes, that is also a great one, a bit more sad though.
  
  Thank you!
