A carbon footprint is historically defined as the total emissions caused by an individual, event, organization, or product, expressed as carbon dioxide equivalent. In this Earth Hour, reduce your carbon footprint by trying any of the below 7 ideas from Huffington Post: 1) Stop Eating (or Eat Less) Meat. The single most effective action you can take to combat climate change is to stop eating meat. 2) Unplug Your Devices. 3) Drive Less. 4) Don't Buy “Fast Fashion” 5) Plant a Garden. 6) Eat Local (and Organic) 7) Line-Dry Your Clothes.

Try to avoid buying/using any items stored in plastic. This includes takeaway food and coffee, straws, and bottled water.

During Earth Hour this year, plant a tree either in your back garden or somewhere in a pre-approved area. Trees are fantastic for the earth, and for our health.

This Earth Hour, try avoid eating foods that have been preserved with pesticides. If you can, try doing this the whole day. Eat organic, or even better home grown, fruits and vegetables. They are just as delicious!
