Earth Hour 2019

EARTH HOUR THIS YEAR IS ON SATURDAY 30 MARCH. 

Switch off for your world.  

In the UK, every year millions of us take part in Earth Hour. By making pledges to help our planet, and by being part of a movement of hundreds of millions more around the globe, we can show we’re fighting for our world. 

We are the first generation to know we are destroying the world. And we could be the last that can do anything about it. We have the solutions, we just need our voices to be heard.  

That’s why Earth Hour is so vital – it gives a powerful voice to people everywhere who want to put the world on the path to recovery.   

The world’s biggest landmarks – such as the Sydney Opera House, Empire State Building, the Eiffel Tower, Buckingham Palace, and Edinburgh Castle – switch off lights as a visual display of their commitment. And you can switch off too.  

Join the global movement this Earth Hour – switch off your lights and be part of the change.

Planet in Crisis

Our world is under threat like never before. We’re destroying forests, choking the oceans with plastic, decimating wildlife population sizes, and causing devastating changes to the climate. 

The problem is we think we have time. But nature needs life support right now.  

  • Wildlife population sizes have plummeted by 60% in less than 50 years. 
  • One in six species is at risk of extinction because of climate change. 
  • There could be more plastic in the sea than fish by 2050 . 
  • We lose an area of forest the size of a football pitch every two seconds . 
  • Food is a major driver of wildlife extinction. The food we eat in the UK alone is linked to the extinction of an estimated 33 species at home and abroad  
  • Nature provides our life-support system - from the air we breathe, to the water we drink and the food we eat. We cannot survive without it.  

How Earth Hour helps: 

Many of us feel powerless in the face of overwhelming threats to the planet. But when we all come together for Earth Hour, we create a strong voice that can change things for the better.  

The power of our combined voices has already helped to: 

  • Influence climate policy in Russia, Argentina, Ecuador and Wales. 
  • Successfully push for planet-friendly laws, such as a ban on plastic in the Galapagos Islands. 
  • Inspire the world's first Earth Hour protected forest in Uganda. 

And 90% of people who take part in Earth Hour say it inspires them to do more to protect the planet.
