I've been looking into #veganism for few years now.
Have tried following too.
But I think one way to start reducing animal cruelty is by introducing and promoting veganism or anti-animal cruelty by things that are easy to shift.
Which is leather, and using animals for transportation.
As I find vegan diet to be controversial as veganism is love towards animals which is part of nature.
While our omnivorous diets are also what have been natural and going against it does show us decline in health which can be helped through supplements.
Which again is controversial when it comes to factory made and helping big pharma etc.
