Joel Tickner is a professor Umass Lowell and founder of the Green Chemistry and Commerce Council (GC3). This conversation revolve around Chemicals in the products we use in our everyday life. Why chemicals are so ever present? To what extent and how should we worry about them and what can we do as consumers to take care? We speak about why chemicals-free is probably not a possible vision. What the difference is between synthetic and natural and what it means with regards to safety. We speak about risk and hazard, ways to think about chemicals and much more. This is a really hands on, useful conversation for those worried or curious about chemistry in our world today and why they are in our world in the first place as well as how we need to change our practices to get to something that looks like sustainable or green chemistry.
