Reducing Pollution Inside your Car
Car interiors may be made of materials that cause allergies and respiratory problems. Companies like Volvo are manufacturing "eco-friendly" and "hypoallergenic" seat and seat belt materials.
Over-cleaning the home can lead to "super-bacteria", germs which are resistant to our most powerful cleaners and our bodies' immune systems. That said, you can be clean without breeding supergerms.
