Hey @morahn, some of the paragraphs are just copy-pasted/reworded from sources which you haven't mentioned in the references. This is an act of plagiarism. steemSTEM is strict about plagiarism and won't support any plagiarist. The images used aren't properly cited either and I am pretty sure that they aren't free for commercial use. Please go through this FAQ on writing steemstem posts.
