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 recycling Christmas cards, mobile phones, and even bicycles.
A robot which specialises in recycling also got your attention and we have photos from the Manor West Centre, Alvins coffee bar, Grange Primary School and St Joseph’s School.
There’s much more besides but why not find out yourself by taking a look through this archive collection of images.
