 Environmental pollution kills 9 million people globally. Three times more than AIDS, tuberculosis and malaria combined. Pollution in America disproportionately affects the poor. Families without healthcare, children and occupants of low-income housing. But when sources are known, we can prevent toxic exposures. We have a practical, inexpensive and scalable solution. Within five years, we will reach and protect billions of people. Our solution honors equality and inclusion of all members of society. We identify and control pollution hazards before they can escalate into disasters like Flint, Michigan. Our solution is comprehensive. We identify toxic exposures. We advance policies to protect human health. And we work with industry to avoid toxins in the global supply chain. Once we diagnose the problem, we put boots on the ground. We implement these interventions on a global scale. And we measure the success in real time. We at the Biodesign Center for Environmental Health Engineering have created an expansive network of international experts and collaborators. We have a track record of impacting U.S. policy and of improving human health worldwide. Health engineers have done it before, saving millions of lives with preventive innovations. Drinking water disinfection and effective wastewater treatment come to mind. It's time for a third wave of preventive health engineering to improve the human condition. Let's start a new chapter in global health protection. Come join us!
