"We often keep tabs, laptops and desktops running at home and in the office," Parambrata, the new WWF (World Wildlife Fund) Brand Ambassador told PTI here.
"It is high time we rationalise things by working on just one device and switching off others," the actor said.
"And, the more this planet moves towards doom due to the greenhouse effect," Parambrata, known for his role as inspector Rana in the Sujoy Ghosh-thriller, said.
Parambrata said he would not only spread the message of Earth Hour among friends in the Tollywood fraternity, but also take his campaign to the social media.
"I will post comments on Facebook and Twitter and ask my fans and friends to switch off energy-consuming appliances or rationalising their use," he said.
