Volunteer at a stranding center or wildlife rehabilitation center. Many environmental organizations rely on volunteer support. Become better informed by reading, taking classes, and supporting environmental groups. Share your environmental concerns with your friends. Even everyday conversations help increase knowledge, awareness and commitment.
Many household products contain toxic ingredients that find their way into the water and air.
Consider the environmental impact along with price, quality, convenience, and brand name when you shop. There are plenty of non-toxic cleaning methods that are just as effective as toxic ones, far less expensive, and nonpolluting. And refilling containers helps with the problem of excess packaging. Look for books on the subject. Look for acceptable commercial brands of non-toxic cleaners.
