Seeds are being delivered to every mailbox in town, all in hopes of purifying the soil using a technique called phytoremediation.Sunflowers can absorb many different toxins and chemicals from the soil and then store those chemicals at the cellular level.

We're all familiar with the image of dogs guiding people with vision loss along streets and through public spaces. But unless you've actually benefited from one of these specially trained animals, you probably have no idea what wonderful mobility tools and loving companions they can be.
The guide dog is a "mobility aid" that can enable people who are blind or have low vision to travel safely. Guide dogs can guide people around obstacles and through crowds, stop at curbs and stairs, and sometimes even be trained to find a limited number of objects that are within sight when given orders such as "Find the chair," "Find the door," or "Find the elevator." The guide dog user can also train (or "pattern") the dog to find frequently used landmarks, such as a bus stop pole or a mailbox.
