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 paper, aerosol cans and even CDs.
Used Christmas cards have also got your attention and we have photos from Harton Junior School, Tyne Dock, Simonside Primary and Marine Park Primary 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.
