Pulp facts

* Deforestation caused by paper production is thought to be a bigger cause of global warming than transport.

* Each person in the UK gets through 250kg of paper a year. The worst offenders are the Finns at 333kg. The average Somalian uses 20g.

* Much of the UK's paper is barely used and a large proportion ends up in landfill. Just 42 per cent is recycled – but as there are so few recycling mills in the country, most of this ends up being sent abroad.

* It is a myth that most paper comes from sustainable sources. Seventy per cent of it comes from natural forests.

* The UK produces virtually none of its own pulp and imports 80 per cent of its pulp.

* Around 75 per cent of the paper for magazines is production wastage and is never read.

* Advertisers know that 99.7 per cent of recipients of junk mail throw it away unread. They think it's worth it for the 0.3 per cent who might.
