  • Watch: Alex Beresford presents Climate Changes on ITV News.

Climate change is one of the biggest challenges facing us as a species.

Human activity during the past 200 years has left us standing on the brink of an environmental disaster - but it is not too late to make a change.

ITV weather presenter Alex Beresford has been finding out about the small, positive ways we can minimise our impact on the environment as part of a new series on ITV News.

This includes looking at minimising the amount of food we throw away every week...

‘Main driver of the loss of forests’ - the impact of wasted food

According to Hubbub, the average UK family wastes around £730 a year on food which goes straight in the bin.

The World Wide Fund for Nature (WWF) estimates 40% of food produced globally is lost or wasted.

Wasted food represents around 10% of global greenhouse gas emissions, which is nearly four times more than global airlines.

It is the main driver of the loss of forests, grasslands and other critical wildlife habitats, according to the WWF.

Liam Sweeney, from Hubbub, joined Alex at a supermarket to discuss food wastage - and shared his top tips on how to avoid throwing products away.

Liam Sweeney shares his top tips on how to avoid wasting food after a shop.

“If you plan your meals for the week, you only buy food that you need and it means your food will stretch further,” he explained.

“Most people avoid it because it can be a bit boring but if you make it fun, involve the family, think of the foods you look forward to eating, then that’s fine - you know what you’re having and when.”

Here are some of Liam’s top tips:

  • Only buy the things you need and stick to your shopping list

  • Make sure your fridge temperature is between 3-5 degrees Celsius, to keep food fresher for longer

  • Buy tupperware to store food

  • Make use of your freezer
