Great post, Joan.
It's sad to think that although everyone knows how endangered rhinos are, poachers and their customers included, they cannot bring themselves to sacrifice their own self-interests to let them survive. This is a flaw in the humanity of humans.
Any attention you can bring to the issue is worthy of the effort.

Agree with you @quillfire humans think they are in control, their interests/needs come first. Humans have forgotten that we are supposed to look after what we have and everything that lives on our blue planet.
