When you feel the breeze on your face and leaves beneath your feet how does it make you feel?

When you remember back to your childhood to a time when you ran through meadows or felt sand beneath your toes what does it stir up in your soul?

For me, these feelings and emotions, stirred up by nature and the love I have for our marvellous planet, make me feel alive.

I can feel my heart beating and the blood pumping through my veins and I am reminded that our environment is as precious as we are.

As Valentine's Day approaches, I have an overwhelming sense of guilt. I feel guilty because I wish that we all showed as much love to our dear planet as we do for one another.

I have a love-hate relationship with Valentine's Day. Each year, Christmas passes and the shops suddenly fill their shelves with red, pink and purple products appealing to 'romantics' who want to demonstrate how much they care for their loved ones. It's a harmless sentiment, but buying-in to Valentine's Day feels more and more superficial each year.

Don't get me wrong, I love nothing more than romantic gestures and I am a sucker for a bunch of beautiful garden flowers, but it needn't be contrived.

I tell my husband and son that I love them every single day and I know that they don't need me to buy them an overpriced greetings card to prove it.

This year, there is a wonderful way that we can all show the love on Valentine's Day... by simply turning our hearts green!

Let me explain. The Climate Coalition is the UK's largest group of people dedicated to action on climate change and limiting its impact on the world's poorest communities.

Its aim is to see a world using 100pc clean energy within a generation.

It's a bold and ambitious objective, but it has to be achieved if we want to see our wildlife and green spaces survive environmental catastrophe.

We are all aware that the pressure on our wildlife has never been greater and climate change poses the single biggest threat to our much-loved natural world.

The turtle dove is on a path to extinction if we do nothing to help and it will be gone from our countryside by the time my little boy grows up.

Can you imagine the sound of our countryside with no turtle doves, skylarks or swifts?

I certainly can't. That's why, this Valentine's Day, I will be wearing a green heart to show support for this ambitious campaign to have 100pc clean energy.

And change starts with us; you and me. 100pc clean energy within a generation is possible – but only if enough of us show we care and want to make it happen.

So this Valentine's Day will you join me and show your love for our natural world that will be affected by climate change?
