President Trump was not the first to notice that many federal science regulations had become bottlenecks — the AquAdvantage salmon, an Atlantic fish that simply has a gene from a Chinook salmon that allows it to grow faster, was held up in regulatory limbo from 1996 until late 2015. There was never a substantial science, health or ecological concern; the government simply didn't know how to regulate it under old rules. To try to streamline approval for the 21st century, the FDA has produced new guidance on genetic editing of "animals," which will include mosquitoes — a few species of which are ecologically useless disease vectors for yellow fever and Zika and can be controlled with biology better than chemicals — and the invasive diamondback moth, which eats crops such as cabbage and broccoli. Transgenic solutions for those are in the works. Meanwhile, USDA proposed new rules for biotech plants, which would mandate approval based on risk to the environment and human health — not just because they have been genetically modified.
