Here they go again. Congress is once again considering “fast track” approval of the controversial Trans-Pacific Partnership (TPP) agreement. Fast track means no public hearings, no floor debate, no amendments — no civic engagement whatsoever.

The stakes are high. The TPP would be the largest trade deal in history, covering 792 million people and about 40% of the world’s economy. If fast track is approved, rules affecting food and farming — among many other sectors — will be negotiated completely behind closed doors.

More and more public health experts are turning their attention to how we can prevent childhood diseases, rather than hunting for cures. This was my takeaway from an inspiring two-day meeting of scientists in Austin earlier this month.

Children: Food and Environment, sponsored by our partners at the Children's Environmental Health Network, brought together dozens of pediatric researchers from a wide range of disciplines. All seemed to share a recognition that environmental exposures are playing a key role in undermining our children's health, and that the resulting problems are both urgent — and preventable.

Later today, the Hawai'i House Committee on Agriculture will take up an important bill that could create new protections for children from pesticides. But if prior votes are any indication, the committee — and the industrial agricultural interests driving it — will be a tough obstacle to overcome.

We've seen this same showdown on island after island, as each county has attempted to enact new protections on the use of pesticides or pesticide-promoting genetically engineered seeds and crops. And we've also seen the force with which, each time, Monsanto and the rest of the Big 6 pesticide corporations have tried to stop these laws in their tracks.

Before you head off to celebrate Valentine’s Day dinner with your loved one, take a moment to send some of that love to the hardworking men and women who put all that good, fresh food on your table.

If you're reading this before 11am pacific time on February 13th, you can send a "Thunderclap" valentine to EPA's Gina McCarthy, asking her to take a stand to protect farmworker health. All of the resulting tweets and Facebook posts will appear en masse Friday morning.

I'm not trained as a public health scientist, but I've learned how to decipher epidemiology studies since I started working at PAN — and a good thing, too, because this stuff is interesting.

Case in point: A new study reports that when developing mice are exposed to a pyrethroid insecticide called deltamethrin, it results in impacts on brain chemistry and changes in behavior similar to what's observed in attention deficit hyperactivity (ADHD). Like I said, interesting stuff.
