What are the ethical issues of cruises giving uneaten food to homeless people in ports?

Melissa N asked:


So much food is wasted on cruises every year..
Maybe cruise companies can start donating wasted food at ports?
What’s wrong with donating the food at the port areas for human consumption?

If it’s going to be thrown out anyway, why not?

I know I asked this before but I want the ethical issues here.
Say they did this in extremely poor countries.
