This week I added my support to Earth Hour – the world’s largest annual event to protect the planet – and joined a movement to safeguard nature and set it on the path to recovery.

Millions of people take part in Earth Hour each year – a global ‘lights out’ event on March 30 aimed at highlighting the message that it is unacceptable to sit back and watch the destruction of nature.

Earth Hour has already helped us find solutions for environmental challenges such as influencing national climate policies, planting new forests in Uganda and banning plastic in the Galapagos.

This is an event which gives a voice to people everywhere, who want to raise awareness of some of the biggest environmental challenges we are facing. I hope even more people will take part this year.
