On average, humans consume about one kilogram of food, two kilograms of water, and about twenty kilograms of air per day. As human beings, we consume a lot of oxygen every day and this allows us to thrive and live healthy lives. The quality of our air supply can have tremendous effects on our health. One major health risk from breathing toxin-filled air is that it can lead to birthing a child with autism. According to a recent study conducted by the Harvard School of Public Health (HSPH), exposure to airborne toxins during a women’s third-trimester of pregnancy was shown to increase the risk of her child having autism.
