No Bread please!

Will people ever learn???
We discover things in this World to make it a better place; The Human's of this World are told the right things to do, yet some still continue to do the wrong thing.
Here they're doing the wrong thing, even though there are signs around to say what is right & what is wrong.
I went for a walk to Princes Park where I saw these people feeding the Swans, Pigeon's, Seagull's & Ducks White Bread. HONESTLY WHY????
