What would be a good topic for my speech?

omg in my freshman year of highschool i did a speech on veganisism for public speaking and everyone loved it! o would so go for that if its something u strongly bieleve in it! but instead of shoving it down ppls throats i educated them on what happens in the meat and dairy industry's and i even convinced some classmates to go vegan and vegetarion! be rlly informative tho so they can mentally picture and relize what happens in slaughterhouses and dairy "farms". i showed pictures and videos, and one of the things i did was i showed a picture og a heathly free-range pig and then a pic fo a ill pig in a slaughterhouse. after seeing the pics, even the meat eaters were saying they wouldnt want to eat animals that were so ill and diseased! its a awesome topic that i think needs to be covered becuase humans need to relize that we can live WITHOUT eating animals or anything they produce what so ever! unfortunitly the dairy and meat industry have ppl brainwashed that thats the only way we can get protien and calcium, when they rlly cause more problems. also inform ppl on all the other yummy foods and recipes they can eat while not consuming animal food products! hope i helped! :)
