Well I get where your coming from but please keep in mind.
The dead animals = protein is inaccurate, a false claim made to promote certain agendas, we know how the negative like to do get every one addicted to certain foods etc.
And with so many bibles and so many miss interpretation of them, to sever whoever for whatever reason they want people to believe something, should be kept in mind also.
And it's written in parables, not to be taken literally.
Animals, Big strong animals get All their protein from vegetation. Fruit, with it's natural sugars is particularly good for Humans for the perfect energy source 'cos the sugars in fruit are all converted to energy, leaving little to no wastage.
I'm 65 next month, have not eaten animals for nrly 50yrs, I eat lots of organic veg + some seeds/nuts & grains (fruit is not so available this time of yr in the UK, especially organic).
The only down side to lots of veg I can think of is its starchy, with lots of fiber.

Thank you sky, I do consider all of this yet the long term vegetarian diet has not made me feel strong. I do regular exercise for decades. Still losing too much muscle. I do not ask doctors to help since they don’t. It is wonderful that your diet supports you so well.🕊️🙏♥️
