The editor of Popular Science needs to screen the text of such articles. This kind of article should not be the direction of Popular Science. Nothing scientific was given in the article. If you went down the path of the article, it would seem to suggest people should not breathe air because they generate C02, should not eat because they excrement methane producing materials, should not use electricity because it means power plants are needed. Yes we need to be mindful of the resources and the planet God gave us and be good stewards of it, but this article is so far from being one of science that it is shameful to see it even represented from an American Company, let alone one with SCIENCE in its NAME.
