iREPORTERS SIGNED UP
Created July 7, 2011 by
Are you a backyard eco-warrior in Munich, Germany? Or saving the world one recycled bottle at a time in Sao Paulo, Brazil? Wherever you are in the world, CNN wants to know what you are doing to reduce your carbon footprint.
No idea is too small! We want to see what you are doing to make our world a greener place to live. It's easy, just grab your mobile phone or camcorder and film what you are doing for a couple of minutes and upload it to iReport.
So, no matter where you are in the world, send in a video of your green ideas in action, or other ideas you've seen at work.
One such innovation is the creation of an 'ashtag' smartphone app by the University of East Anglia in the U.K. that enables people to send in images and data of ash trees hit by a devastating disease called ash dieback that has infected millions of trees on the European continent.
If you have seen such trees - send us your images and tag them #ashtag - but ensure you take precautions such as cleaning your footwear after visiting any wooded areas. The U.K. Forestry Commission has advice on what to do in affected areas.
