You have been hired as a public relations specialist to give invertebrates a good name. After all, they are much more than just creepy crawly bugs!
Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature.
Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.
