KARACHI: Millions of people across the globe observed the World Earth Day by switching off lights for just one hour.

United Nations Secretary-General Antonio Guterres had appealed that all the lights be turned off for one hour tonight at 8pm.

A large number of people around the world can reduce carbon emissions by turning off unnecessary lights and electronic devices for one hour to celebrate Earth Hour to protect the environment.

Under Earth Hour, environmental action would be taken on a large scale, he said.

“We all have to play our role in climate action. I appeal to all the citizens of the world wherever they are to turn off their lights for one hour at 8 pm local time,”Antonio Guterres said.

The event launched by World Wildlife Fund (WWF) during 2007, is part of an annual tradition to raise awareness about climate change.

It is pertinent to mention here that Earth Hour is celebrated on the night of the last week of March every year by the United Nations throughout the world, including Pakistan.

The aim is to invite people to think about the negative effects of pollution and other factors on the environment.
