If you know where to find a good plastic-free shampoo, can you tell Jeanne Haegele Last September, the 28-year-old Chicago resident 1 to cut plastics out of her life.

She was also worried about the damage all the plastic 2 was doing to the environment. So she 3 on her bike and rode to the nearest grocery store to see what she could find that did not include plastic. "I went in and barely bought anything," Haegele says.

But those who have tried know it is far from easy to go plastic-free. "These things seem to be so common that it is 10 impossible to avoid coming into contact with them," says Frederick Vom Saal, a biologist at the University of Missouri.
