First Nations help translating?

Ok, Im working on a song called "Save My Tomorrow" There is a chanting part in it and I thought it would be super groovy to put actual Native tounge in there if I could. If anyone knows how to say anything related to environmental positivity, a line or word I could repeat, should rhyme with "hey" but I can make it work anyway. Even if you just know small words like : tree, sun, river, I'll take what I can get. Please tell me the language too. Also, please no Norwegian, German, Phillipino, or otherwise saying "I like poo" and tell me its something else. You silly buggers:) Thanks!!
