Animal Rights are
shamefully unprotected by international law, international organizations and its member states. Despite the fact that already exists a Universal Declaration of Animal Rights, proclaimed in Paris on 15 October 1978 at the UNESCO headquarters:

Suspiciously, the text of that Declaration of Animal Rights CAN NOT BE FOUND in the UNESCO website, unlike the Universal Declaration of Human Rights:

There's an entry at Wikipedia about a project of Universal Declaration on Animal Welfare (
https://en.wikipedia.org/wiki/Universal_Declaration_on_Animal_Welfare), where the declaration of 1978 is cited as "historical background". This project was conceived in 2000 by a group of animal welfare organizations and after several drafts, till the last one in 2014, nothing could be achieved, except affirming the repeal of fact of the declaration of 1978. This is a dirty trick from the corporations that exploit animal suffering.
It's impossible that non-governmental organizations can achieve the necessary pressure against the corporative lobbys, since they don't have an independent funding. That's what makes necessary the actual participation of the governments of the member states for the purpose of attaining international standards for regulation of animal rights and thus achieve the effective commitment of those member states.
