If you don’t have knowledge, you cannot act. That is why I am so enthusiastic about the many practical apps that are now available: With their help, you can find out about the ingredientsof almost any product in a matter of seconds, what is good and bad about these substances and whether the product as a whole is good or harmful. You can learn all this just by scanning the barcode. If you scan some of the products you use at home in your daily life with these free apps, you will be amazed at what you will learn. As a first step towards a life with less plastic, I therefore recommend you simply look up what you already have on your shelves. Then you can decide whether you want to continue using these products or, if necessary, look for alternatives.
