Chief Looking Horse honors the healing journey by riding with the Bigfoot Riders by horseback every December 15-29 in severe temperatures, which all the committed Bigfoot Riders endure to understand the immensity of the hardship of Chief Bigfoot and his band. In 1993, Chief Looking Horse traveled to New York with elders of different nations for the United Nations' Cry of the Earth Conference where he did the opening prayer. The Unrepresented Nations & Peoples Organization invited him to Holland to pray for peace and unity in 1994. New Orleans honored Chief Looking Horse by proclaiming August 27 as White Buffalo Day, and he was given the key to the city by the mayor in 1996. He was also awarded the prestigious Canadian Wolf Award in 1996, given to a person who has dedicated their life to working for peace. The first award was presented to Nelson Mandela, the President of South Africa.

Ta’Kaiya Blaney is from the Sliammon First Nation and is 12 years old. She feels that as humans, as participants and beings that walk upon this Earth, it is our responsibility to help the Earth. We all need to take steps toward a clean and healthy future regarding animals, humans, plants and the various ecosystems. Our Earth is our home. Over the past four years, she has been an advocate for providing better qualities of living in Indigenous First Nations territories, and ending the oppression, racism and corruption Indigenous peoples face from government and within their community. Ta'Kaiya has spoken at UN meetings across the globe, including The TUNZA UN children and youth conference on the environment in Bandung Indonesia, and the Rio+20 UN conference on the environment in Rio de Janiero.

"I advocate to change not only the human condition, but also the condition of our planet. In my culture, it’s a fact and an understanding of life, that everything is connected, and we were put on this Earth to be stewards and caretakers of the environment. In my culture, it’s a teaching to do more than connect the dots, to see the picture as a whole. I feel that advocating, and speaking at mere conferences isn’t enough. Actions speak louder than words. I’m inspired by the work you are doing, and the message of protection and change that you are broadcasting to the many generations. I would like to do the same. Emot (Thank you)."
