Earth Hour Day – Meaning, History, and Facts

Earth Hour Day is a worldwide campaign/movement organized by WWF (World Wide Fund for Nature). It is held annually to encourage individuals, societies, communities, shopping malls, corporations, etc., to turn off electric lights that are not essential for one hour. Thus, that specific hour will be called Earth Hour Day.

Event Timings are usually 8:30 to 9:30 pm (in the local zone) towards the end of March, and generally, the last Saturday of March is the key focus day every year.

It is not limited to electricity. Here, the main motive is to raise awareness among the world’s people about climate change. With the increase in global warming and other environmental issues, many adverse effects on Earth have been seen in recent years.

We, the people of planet Earth, have to act against the rising temperature of the earth and focus on how to save energy for our future generations. Earth Hour Day is the initiative to fight against all the negatives and convert them into positives.

Earth Hour Day History and Wiki

The concept was first created in the year 2004 when WWF Australia discussed ideas with an advertising agency named ‘Leo Burnett Sydney’ for influencing people to act together on the issue of climatic changes. Large-scale switch off the idea of electric items first came in 2006, with the title named ‘The Big Flick’. WWF then presented their concept to Fairfax Media and Sydney Mayor Clover Moore, who agreed to give full support.

The first Earth Hour Day was held on 31st March 2007 in Sydney where approx.2.2 million homes and businesses switched off their unessential lights for one hour. In October 2007, San Francisco did the same activity inspired by Sydney’s activities. After a successful event, the team decided to run this activity every year in March.

In 2010, 128 countries and territories took part, and the world’s iconic buildings and landmarks from one ocean to another stood in darkness.

In 2011, the campaign title was named “Beyond the Hour”. This tagline was created to pledge that we will take care of our mother earth even after Earth Hour Day, i.e., we will reduce the consumption of resources throughout the year. The new logo was 60+. Previously it was “60”.

Here 135 countries took part with a record of 5251 cities and towns. The event also focused on “endangered species” like dolphins and tigers and saving them.

In 2012, the Headquarters of Earth Hour was moving from Sydney to Singapore. Here more than 7000 cities across 152 countries took part in the event.

In 2013, Earth Hour Day was held on 23rd March, and timings were the same 8:30 to 9:30 (locally). Many initiatives were taken place globally, such as;

Earth Hour 2019

It was held on 30th March 2019. The theme of Earth Hour 2019 was “Reduce, Reuse, Change the Way We Live“, this theme supports renewable energy and support recycled products. But we Have one question – Do we really need any tagline to work on it? The answer is NO. As human beings, every problem related to Earth is a major problem that we need to control.

If you think that what’s the benefit behind it!! Is there any profit motive? The answer is again NO. Here we do things according to our needs, feelings, and duty towards “Mother Earth”. No one is forcing us to follow any trend, but our sole responsibility is to give back to Earth all the care it deserves.

Rome wasn’t built in a day; in the same way, we cannot change daily activities in one day, but together we can change the whole Earth’s resources consumption pattern. Starting today, save as much energy as you can and advise other people to follow the same.

Earth Hour 2020

Every year we celebrate Earth Hour with a particular theme, but the main focus of this year was on the Australia bush-fire this year. Also, due to covid-19, people stayed home and safe with family.

This wildfire was one of the devastating events that happened in Australia. This wildfire has destroyed more than 8 million hectares of land and affected over one billion animals, along with the loss of human lives. It is a significant loss to the environment.

WWF-Australia has launched a plan to plant approximately two billion trees by 2030. This is a great initiative taken by WWF-Australia to support the wildlife destruction caused due to bushfires.

Apart from the Australian bushfire, many other environmental problems were considered in Earth Hour 2020. For example– As per the announcements made in the Global Climate Action Summit (held on 14th September 2018), the main agendas that were focused on this year are;

• Minimize food loss and waste up to 50% by 2030.
• Global Environment Facility announced funding half a billion US dollars to improve land and conservation of forest.
• As per the Walmart announcement, a platform will be developed to stop deforestation, minimize carbon emissions, etc.

The global leaders set the environmental agendas during the Key Global Conference and Forum this year. In this conference, decisions were taken on the most crucial environmental topics such as climate change actions, nature protection, and sustainable development for the upcoming decades.

It was an excellent opportunity to combine the voices of millions of people across the world to deal with environmental issues.
