Don't need no stinking science! The "Precautionary Principal" says that we figure out what the environmental and health costs of our technology will be before we advance a new technology, drug, chemical, etc. onto market/public practice. We don't do that. Our agencies aren't funded well enough to do testing, so, industry does it for the agencies or not at all. NOW, the push is to forget about that, even, and ignore the most crucial science studies about the object of new rules and go ahead anyway. Drop or create new rules based on what industry wants, regardless! This is how it was before. I was an organizer then, too. I helped work to get to where we are. Now we are going backwards if this works for Trump.
