We know you encounter things in your environment that make you curious. And Citizen Q is our series where we can help you find answers to your everyday environmental questions. Maybe you want to know what your carbon footprint is. Or if the recycling you're lugging out to the curb every week is really making a difference. Whatever it is, we want to know what's on your mind. Send your question to firstname.lastname@example.org, or check out what's on other listeners' minds below.
