Cop 26, which is the United Nations Climate Change Conference is being held in Glasgow and lasts until November 12.
Closer to home, lots of you have been doing your bit to help the environment over the years including by recycling batteries, textiles, and bags.
Used Christmas cards have also got your attention and we have photos from Richard Avenue Primary School, Academy 360, Benedict Biscop and the Bridge Women’s Centre to show you more.
There’s much more besides but why not find out yourself by taking a look through this archive collection of images.
