Miranda Kerr: Turn the Lights Out for Earth Hour!

Miranda Kerr carries her 14-month-old son, Flynn, back to their apartment on Wednesday (March 14) in NYC.

The 28-year-old Aussie model was recently announced as the ambassador for this year’s Earth Hour.

“Earth Hour is [all] about encouraging positive action and that is exactly why I have chosen to be involved. I believe we can all do our best to make small changes to create positive effects,” Miranda wrote on her Kora Organics blog.

“I urge us all to be involved and join in the conversation and of course don’t forget to turn the lights out at 8:30 pm March 31st 2012,” she added before signing off with “Love and light(s out).”
