@madhur Insects don't have blood at all actually. They have something diffierent called Hemolyph.

What i find interesting is that while I do react to most insects with disgust I also have a great deal of empathy if i see one in pain or suffering.

@madhur
Is interesting andin my current thoughts I see a benefit in animals or anything that can elongate life (make go longer without too much digging in, something more 'sustainable'; multifunctional to land / people / gives something more worthwhile to do than finance/ meaningful low-scale widespread etc.... IF people can care for animals and kiss them and then at the end of life in some way- when it feels right - and animal is ready or asking for it - to give it your sharpest blade as you might wish and be blessed in the process...

(prepare, ask gently, meditate, look at your knife if it's the day for it and as you prepare).
Then make it clean, least suffering. Ritual / Spiritual passage..

giving a pause

.....

For me, taking machines out of the equation almost completely (will have to think but I would say say near everything as it will break anyway - to make us even more sustainable / true to nature.)

So If people can care for an animal or two and give each other care with their foods (to animals and humans), this takes care of many other things too :)
Call it diversity for now...

But it's a BIG "IF"...

Amazingly with a bit of thinking I think things can fall in line IF a pyramid of happiness can happen and when things are given meaning to it / them / everything else... even the salvation at the end from living too long or in suffering... solves that which I think is very just/meaningful... + the giving up your life to others can be (even should be!) a kind of passing of spirit from one into the next and has tangible regeneration as body to others also if people should wish it (not everyone, could be mainly veg as the taking care of nature but with forest letting wild pig and deer roam like they do still in many part of main europe and well everywhere I guess in various amounts).

Something like for old dogs but eating them after playing with, growing old together, using the blade to make food (worthy use of time and needed), and to enjoy their kids/off-spring though the memory of them and repeat the process!

Again the impersonal machine-care and mass-scale industrial, de-personalised contact and distanced-living with habitat, is not for me so this integrates all that
(if you read the paragraph making the opposites of some words you get what I prefer or more towards those spectrums of extreme than these ones).

I may have missed out something in this eco-system of happiness, but I'm happy to take advices or clarify (even to myself but I think that 'captures' the ideal spirit of life for me but letting things live and have ways to let them die! Nobody escapes this (and nothing necessarily needs to run away from it when it's their time).
