Shrimps don't suffer. No one 'suffers'.
Suffering is an expresion / concept we humans have because we called a certain state like this. Suffering is something a organism presents if that organism can't survive or struggles with survival.
Now i'm a human and my empathy is a lot stronger for humans, a lot, than for shrimps.
Btw. i do believe if we would really care and make sure fewllow humans would not need to suffer (they need to suffer because of capitalsm), a lot of other suffering would stop too.
We would be able to actually think about shrimps and other animals.
