Sorry for the late reply. I did not see your question. If you look online you will find plenty of petitions.
However it needs to be active and trustworthy. Try WSPA as they usually have many ways to encourage you to help animals and sign petitions.
I don't think that is nothing we can do, when that happens ,we was buyng the food at walmart forever but we toss the receipt in the trash we don't have any evidence that we bough the food there thats the only thing you can have to proved that you bought the food there all this years,i lost both of my dogs one after they show it on tv by November and the other died in February three month apart. 4 years ago.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
