Download the HERO image. Print it and say, once a month, get some fun images of friends and post them on social media. Get some crazy shots, but please stay safe. A3 is best if you have access to an A3 printer.
This is fun. At work or a public place, take the sign and tell people you are for Plastic Free Oceans and say to them “Hold the image, I’ll take a picture on your camera, then check the website on the image. If you like what we are doing post the image to Facebook and Twitter” The first time we did this, on a beach, about 100 said yes and thought it was a great idea – only two said no.
