Interesting concept in the article about inserting nano tech onto plants. There is a few issues with that. First and foremost, is that all of those living creatures (plants and trees are perfect as God created them) so they do not need improving.
Second and just as important, there is already enough light pollution at night being created by humans that is interfering with the eco system. Adding more "unnatural" nano tech into trees will be uncontrollable and make it worse. Light pollution is one reason why people don't sleep well at night, it is affecting other life forms as well. Just because you "can", doesn't mean you should.
Thank you, God Bless.
