I’M writing to encourage your readers to join the thousands of people across Scotland and millions across the world taking part in the biggest event to protect the planet, WorldWildlifeFund’s Earth Hour, taking place at 8:30pm on Saturday March 24.

This year, make a #PromiseForThePlanet and change an aspect of your life to live more sustainably.

This could be switching to a green energy provider, refusing plastic cutlery with take-away food or buying a re-usable coffee cup.

Whilst individually these changes may seem small, together they will have a huge impact and will help to reduce our environmental footprint.

With almost 50% of species at risk of local extinction if global temperatures continue to rise at the current rate, this year’s Earth Hour is focussing on the need for us all to play a part in protecting our planet – for people and nature.

By working together, we can show we care and are willing to take action to ensure –that species such as polar bears, elephants, tigers and marine turtles, to name but a few – will still be around for our children and grandchildren.

Make sure you take part on Saturday March 24 at 8.30pm and make a promise to protect our wonderful planet at wwfscotland.org.uk/earthhour.

WWF Ambassador
