As you’re unloading the groceries, you might see a long, complicated label on the back of your cereal box or dish soap, filled with words you cannot pronounce or chemicals you’ve never heard of. But you think, “Oh well.” Because while you may have different brands to choose from, most of the other products you find on the shelves will also have long lists of mysterious ingredients. So instead of thinking about alternatives, you just keep going back to the store to buy the supplies you need to keep cooking, cleaning, sleeping, working, and so on. Without even thinking about it, we expose ourselves to the harmful chemicals that lurk in everyday products like shampoo, household cleaners, and perfumes. The truth is that most of the time we don’t even know they are there.
