 There are newer things we as a society can do, and there are things individuals can do to lower their risks. So I mentioned that there are certain pesticides that are linked to Parkinson's disease, one called Paraquat. It increases the risk of Parkinson's disease by 150%. More than 60 countries, including China, have banned the pesticide, which is reported to kill the weeds that Roundup can't. But the United States has not. In fact, use of Paraquat in the United States has more than doubled over the last 10 years.
