Great movie to watch is Earthlings (2005). https://en.wikipedia.org/wiki/Earthlings_(film)
although giving up meat and abolishing animal slavery is unreasonable for many due to lack of education and responsibility (e.g. what out-of-the-ground growing things are edible and nutritious enough, how to properly train animals, etc.), we can make steps in the correct direction, so that perhaps one day we won't have to kill animals in order to eat well or put them on a leash and in a cage indefinitely.
disclaimer: since the cow and chicken are already dead, i eat their flesh and remember to be grateful for the sacrifice. i try to get raw milk from small local farms, eat more cheese and eggs. i also walk the friends' and neighbors' dog off leash whenever possible.
be the light thou wants to see in other people.
