Bee Swell http://beeswell.org/ is a wonderful website that promotes awareness of problems our pollinators are facing today. They provide information how to create bee-friendly habitats and how to be on the alert for neonicotinoids (referred to as neo-nics).
They are also offering free posters such as the one pictured here, created by Nora Wildgen.
You can just download them and print them.
Get the word out and post these everywhere you find fellow gardeners!
