Miley Cyrus makes stand against trophy hunting
I may have left B.C. for now but my heart is still very much there.... Along with the grizzlies that when I first locked eyes with changed me forever & the wolves that sing such beautiful songs calling out for one another.... But the hearts of everyone in this photo (John & Mary Theberge, Carl Safina, Ian McAllister, April Bencze, Douglas Neasloss, and my brother Braison) the people of First Nations and caring humans of B.C. will be broken if these amazing creatures are no longer apart of the #GreatBearRainforest... On this adventure something was confirmed that us lovers of nature and all that it brings to this planet already know but unfortunately so many don't understand... WE ARE THESE ANIMALS (if you ever see the bottom of a bears feet as he climbs to shore after catching breakfast you'll know exactly what I'm talking about, I also learned on this trip I have quite the grizzly foot fetish!) .... What separates us from the animals and the land we want to protect is our vocal ability and freedom of speech. It is our responsibility to give the GBR & all the animals it provides a home for a voice! Not only have I fallen head over heels in love with BC but I am completely enamored with @pacificwild and all they do to protect this magnificent place #savebcwolves #stoptrophyhunting
