A little while ago, we wrote about powerful advertisement examples that were designed to raise awareness about important social and environmental issues. But what about animals? They don’t have a way to raise awareness about the issues they face, so it’s up to us to help them out.

Because of our inactivity and little concern to animal rights, according to WWF, there are around 20 species of wild animals in critical endangerment with a lot more vulnerable ones. If we let animal cruelty continue, we might lose such animals as tigers, gorillas, and whales.

These printed ads address different types of issues, but they’re all about giving a voice to the voiceless. Most of us love animals, and yet we remain ignorant of or apathetic towards the abuse of domestic or circus animals or the extinction, poaching, and over-harvesting of wild populations. If you’re an animal lover, consider putting your time or your money behind one of these noble campaigns!

There are lots of powerful animal welfare ads, and we’ve compiled a list of the most memorable ones. Ones that might just help to raise awareness to this awful case.
