I have a question regarding global warming and man-made pollution. If a person were to lock themselves in a garage with the car running, would you ask if the death was caused from the degradation of the air quality or was it a natural death because all humans die? If you dump garbage in your home, your home becomes a garbage dump. It's not fear and panic or a scam ("Distracted from real environmental issues," April 30 and "Global warming not a crisis," April 28, Letters); it's plain and simple common sense. Open your eyes and your mind.
