Colombian President Juan Manuel Santos on Thursday called on all Colombians to switch off the lights for one hour on March 26 and join the global campaign of "Earth Hour."

The campaign, which seeks to create global awareness in the fight against global warming and climate change, is supported by over 4,000 cities from a total of 128 countries which all will switch off the lights from 20:30 to 21:30 local time on March 26.

"Those 60 minutes without lights will be a symbolic act and also a reminder that every day, every hour, in our daily lives we can turn off the lights we do not need, turning off appliances when you are not using them, saving water and think about protecting the planet," Santos said.

Santos said this would show Colombia's support of the environmental campaign, which is led by the World Wildlife Fund for Nature, adding that caring for the earth can not be postponed any longer.

"It will be an hour without light, but with stars, many stars. An hour for our planet, the first of many more," he said.
