Climate Change and paper waste

I am not sure I necessarily fully subscribe to the doom mongers' claims that we only have a few years left before the planet succumbs to global warming and we all go to hell in a handcart. I accept that there is a lot we can do in our own country to reduce waste and harmful emissions but the UK's contribution to global warming must be miniscule compared with the big polluters like China, India, Russia and so on.
However, it is not my intention here to start a debate about climate change or to denigrate those who passionately believe in man's destruction of the planet and are prepared to glue themselves to railings in protest. We are all entitled to our views however extremely we might express them.
What I do want to do, however, is to return to a topic I wrote previously about last November and which continues to get me "steamed up". This is the horrendous amount of printed paper waste from all the leaflets, adverts and so on that pour through the letterbox and burst out of the plastic wrappings that papers and magazines come in (not to mention that plastic itself). Last time I wrote, I did a rough calculation of the amount of excess paper generated nationwide by weekly circulations of the Radio Times, based on the weight of one weekly edition's supplements and adverts in our house. I came up with a figure of 250 tons of excess paper from this one magazine alone. How many forests are being destroyed to make all this paper?
I am sure it is getting worse lately. Not only are magazines stuffed full of rubbish but the poor old postman is now obliged to feed it through our letterbox. On days when we have no other actual post he/she is still required to use up fuel and footwear delivering to houses that would otherwise be bypassed.
Maybe our charities, advertisers and other proliferators of such waste could do their bit towards improving things. Screams of protest about affecting their income from sales or donations but I am sorry; it's a question of priorities.
