Hello, I'm Zefr. Your recent edit(s) to the page Genetically modified food appear to have added incorrect information, so they have been reverted for now. If you believe the information was correct, please cite a reliable source or discuss your change on the article's talk page. If you would like to experiment, please use your sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. ''You're a student, so you need to read more before editing. Don't use class notes, which are not a WP:SECONDARY source. For human toxicity, you would need a WP:MEDRS review.'' Zefr (talk) 04:10, 24 March 2022 (UTC)


 * Thanks for your correction. I'm a student and learning how to better edit on Wikipedia. I will try to use more good sources to support my writing next time. JianingGuo (talk) 02:31, 23 May 2022 (UTC)

Your edit to Coin has been removed in whole or in part, as it appears to have added copyrighted material to Wikipedia without evidence of permission from the copyright holder. If you are the copyright holder, please read Donating copyrighted materials for more information on uploading your material to Wikipedia. For legal reasons, Wikipedia cannot accept copyrighted material, including text or images from print publications or from other websites, without an appropriate and verifiable license. All such contributions will be deleted. You may use external websites or publications as a source of information, but not as a source of content, such as sentences or images&mdash;you must write using your own words. Wikipedia takes copyright very seriously, and persistent violators of our copyright policy will be blocked from editing. See Copying text from other sources for more information. ''Both passages that you inserted in were copyright violations, of an article visible at encylopedia.com years ago  and a 2011 piece from inquirer.net. Your later edit so lightly paraphrased the Britannica article which you cited that it also constitutes a breach - see Close paraphrasing - but also distorted the meaning ("The phenomenon of mining", "Mining models made by punching mechanisms"), and by truncation, obscured it.''
