Exactly, there is still things we can do, but we wont be able to do any of the much needed things under capitalism at all and we also dont have much time to do something anymore, so its still really fucking urgent.
(An idea for example: go full hydroponics with hydroponic farming skyscrapers in cities, abolish most normal farmland and let woods grow everywhere where there were farmlands before. It provides pesticide free food and a great long lasting carbon safe.)
Hm, thats a really interesting side effect tbh. But yeah, japan is still extremly problematic society-wise.
