A lot of people question the popular climate change narrative. And sustainable energy is too far in the future for them to care. But the one thing they/we are certain of is cancer among our friends and family. To be honest the term sustainable energy/ future in my mind I just associated it with climate change. From several articles sustainable energy is a thing and it can run out or become very expensive to get. But cancer and other health problems we are all aware of. Is it linkable to gasoline automobile exhaust I'm not sure, definitely to diesel exhaust fumes. If you live around refineries and other petrochemical manufacturing plants you know of friends and family who have had suffered from health issues and cancer deaths, particularly those that work in those facilities.
