by extramarks - Academics - March 30, 2019April 1, 2019 Do you have an hour to spare for the earth? Humans use a lot of energy. In fact, in the year 2015, the amount of power consumed across the globe was 168,519 Mtoe (Million Tonnes of Oil Equivalent). Needless to say, we’re the ones who have changed the way we and other species have experienced and continue experiencing the world. The one thing that sets us apart as a species is our ability to adapt to our environment as per our needs and wants. We change our surroundings to work for us. One of the biggest examples of this can be seen in the way we live. We’ve built cities, huge urban centres where millions of humans live, work and go about their lives. These cities may be a testament to man’s ingenuity, their indomitable will to build, but they are also major centres of pollution – air, water, and sound pollution yes, but also light pollution. Beyond this, the cities have an entire range of problems of their own – waste, decay and overuse of resources being few among them. But all is not lost. Every year, the world comes together to show solidarity with the only planet we call home. All over the world, it is observed by switching off for an hour. For ‘Earth Hour’. Started by the World Wide Fund for Nature (WWF), the idea of ‘Earth Hour’ movement is to encourage individuals, communities, and businesses to turn off non-essential electric lights for one hour, that is, from 8:30 to 9:30 pm local time. The objective simply is to raise awareness about energy consumption and effects on the environment. The first campaign was kicked off in Sydney, Australia in the year 2007. Earth hour has gained momentum in the past few years with people sharing pictures of the city skyline with the stars visible in the background. A sight that was a distant dream earlier.
