A new study from neurologists at UCLA adds to the growing scientific evidence showing an ever stronger link between exposure to pesticides and development of Parkinson’s disease.

This latest study documents how the fungicide benomyl triggers a cascade of events at the cellular level that increase the likelihood of developing Parkinson’s. The researchers say the findings clarify the role of naturally occurring enzymes in the brain, and may help in efforts to slow progression of the disease — even among those not exposed to pesticides. The study also confirms that avoiding pesticide exposure can only help.

This week we mark the International Week of No Pesticide Use, which honors victims of pesticide poisonings across the world. A week which I wish did not need to exist.

Unfortunately, the problem is very real. According to the World Health Organization, 25 million farmworkers experience episodes of pesticide poisoning in the Global South every year. A new report by PAN Germany highlights this and other sobering facts, illustrating how pesticides continue to harm millions across the globe — and making a compelling case that it's time for real change.

I keep reading about how boys have a harder time at all levels of school than girls. It turns out there may be more going on than the commonly held argument that teaching styles are more conducive to girls' success. Boys may also be at a biological disadvantage — new research shows that their brains may be more vulnerable to harm from pesticides.

As a mom of an infant boy, this has me seriously worried.

Get your kids to exercise, eat right, and control their portions — these steps can help combat childhood obesity, we're told. But new research on persistent chemicals points to the fact that as parents, we're not getting the whole story.

Researchers in Spain found that whether a child, especially a girl, will be obese is not just dependent on lifestyle choices, but also on the child’s exposure to persistent organic pollutants (POPs) before birth. As a mother of a 4-year-old daughter, this worries me tremendously.

I want to share some good news that brightened my day. One of the largest pesticide manufacturers in the world — Bayer CropScience — announced on September 15 that it will withdraw its most hazardous pesticides from the global market. 

This is huge victory for the PAN International network and other NGOs from Europe, Asia, Latin America and Africa who have campaigned for years for Bayer to take this step. While I'm happy that Bayer finally did the right thing, it saddens me that the company waited 16 years to act after it first promised to withdraw these pesticides back in 1995. Who knows how many pesticide poisonings worldwide could have been avoided?
