Miranda Kerr

Supermodel Miranda Kerr’s Earth Hour challenge has been accepted and celebrities all around the world are now making their own “I Will If You Will” challenges to inspire people to take much needed action for the environment.

Miranda Kerr will conduct a free yoga class for the public now that 500 of her fans have committed to create their own “I Will If You Will” challenge for Earth Hour.

Transformers star, Australian actress and keen environmentalist Isabel Lucas, has pledged to plant 100 trees if 100 people plant one tree each.

''Earth Hour is an opportunity to come together to support a cause for the greater good of our planet and our whole human family. A moment to feel grateful for the life giving trees, the air we breath, the food and water that nourish us and the beauty of mother nature,” said Lucas.

“I hope Earth Hour inspires us to consider and integrate sustainable ways of living that respect our earth and one another,” she said.

Style and entertainment stars, Giuliana and Bill Rancic from the reality series Giuliana & Bill have promised to both go out on the town and wear Chicago Bears jerseys at their next event, if 5000 people promise to take part in Earth Hour and turn off their lights at 8.30pm on 31 March.

“The Beast from the East”, Russian former WBA heavyweight boxing champion, now politician Nikolay Valuev, has made a huge promise to organise recycling in the Duma if 100 000 people sign WWF Russia's petition on passing a new law about protection of the sea from oil spills.

This year, Earth Hour has already seen thousands of people accept and create challenges for the ‘I Will If You Will’ campaign, which asks people to make a personal dare at YouTube.com/EarthHour in order to inspire friends, family, businesses and colleagues to adopt sustainable practices beyond the hour.

“Everybody has the power the change the world they live in; it’s great to have such well known personalities use their voice to spread this message even further and connect people with the common goal of protecting the planet,” said Andy Ridley, Co-Founder and Executive Director of Earth Hour.

Cricket legend Sachin Tendulkar, Colombian television presenter Claudia Bahamón, MTV VJ and Asia Pacific Ambassador Nadya Hutagalung, Celebrity Chef Bill Granger, Universal Pictures and the Lorax are all supporters of Earth Hour among many more.

Earth Hour 2012 will take place at 8.30pm – 9.30pm on Saturday 31 March
