There are various ways that you can make this possible and create awareness. You can form a group or join one that is already in existence as well. You can also look out for victims of the cruelties and offer support and encourage them as this can be a great move. You can do donations and try and create support in the school or home place you are at for them too. I am really happy that you are thinking of such great ideas at 13years and I wish you all the best.
