  ''I have become BJF Ambassador because the BJF carries out what is truly required: helping to restore two of the most vital ecosystems on earth.  I think it’s time that we are aware of the fact that we are part of nature and that we are not above it.
To protect nature is human rights. As humans we have rights. But we only can have rights if we respect our environment and our nature. So as a human, I believe it is my duty to become Ambassador of the Black Jaguar Foundation.''

  I grew up in a zoo and thus I became infected with a lifelong fascination for the wonderful creatures that share our planet with us. As a child, little could I expect that the existence of many of these creatures would be at stake barely three quarters of century later due to the exponential expansion of one dominant species, the human being. I, therefore, sympathise strongly with the objective of the Black Jaguar Foundation, to take this rare black beauty as an icon in its efforts to mobilise forces to conserve the natural heritage of the south-american continent.

This is for my future kids, kids!
