Your posts cover a cool, interesting topic. However, they can be found almost identically on various other channels: on Facebook, on runningwildfilms.com, on a donation page... Since you don't mention anything about the previous publication there, I'm not sure if they are actually your own accounts. Could you please put a note in one of your posts there that you are publishing the same post on the Steem? That would suffice as verification of your copyright. Thank you!
