Running a global art marketplace lets you see how different countries regulate risk. I noticed this first with shipping chemicals; Europe and China banned some substances years before the U.S. considered doing the same. Paraquat is another example. When you read about bans across the EU and China, you can see how quickly international policy shifts when a product is seen as harmful. Even if science debates the exact level of risk, many governments move ahead to protect workers and consumers. Countries often ban first and debate later when public health concerns grow. The U.S. sometimes moves more slowly due to legal battles and industry pressure. Thousands of lawsuits show a large group of people reporting the same harm. When multiple countries ban a product, it signals a global risk perception, even if the data isn't perfect. These bans say as much about policy priorities as they do about the chemical itself.
