But Parkinson’s rates in the US have doubled in the past 30 years. And studies suggest they will climb another 15 to 35 percent in each coming decade. This is not how an inherited genetic disease is supposed to behave.
First off, that's pretty wild. But they also make a strong case that Parkinson's has large environmental component. Cool article.

The vast majority of chronic disease isn’t caused by our genes. “The Human Genome Project was a $3 billion investment, and what did we find out?” says Thomas Hartung, a toxicologist at Johns Hopkins. “Five percent of all disease is purely genetic. Less than 40 percent of diseases even have a genetic component.”
