Try to focus not on what others do, but on what YOU do. YOU have an actual impact on non human animals, and by not treating them as though they are worthless or consumable, you are causing less harm. You are not contributing to the ice cold panic they feel when they realize they are the next in line to get butchered, or any other short or long term suffering they go through. That is worth a lot, to the individuals spared from the suffering.
Don't compare yourself to evil people, or uninformed people. Focus on yourself and the good/neutral you keep doing every day. You are kind, thoughtful, compassionate. What you do matters, even if the impact seems small compared to all the suffering.
