Hi, in the city I am presiding there are a lot of homeless people.

A lot of these people are near grocery stores. Considering meat is a high protein source, like if you buy turkey slices, I feel like that lasts (compared to buying something like tofu). So I was wondering whether its okay to buy meat to give it to a homeless person. This forum seems to think veganism is highly impactful so I don't know. 

Or perhaps, rather than donating meat, I could donate money to them? I don't know if that is good either because there isn't really much of a big difference if a homeless person buys meat vs I buy the meat for them.

Furthermore, there are some instances where some argue that homeless people would spend the money on drugs and alcohol. But when I'm not in a position to give food (because I don't have it with me currently), I donate like a dollar. Would this be considered good or bad?
