As Earth Hour’s global ambassador for the second year in a row, Miranda Kerr is bringing the cause worldwide by taking part in the charity’s “I Will if You Will” campaign via YouTube. In her video, Miranda challenges viewers and fans to upload their own “I Will if You Will” challenge to youtube.com/earthhour, with the promise that if 500 people join in, she will conduct a free yoga class. “Earth Hour is [all] about encouraging positive action and that is exactly why I have chosen to be involved,” Miranda said. “I believe we can all do our best to make small changes to create positive effects.”
What will your challenge be?
