Richard, bamboo is inevitable for most paper. 

The world's biggest paper plant is in Southeast Asia:
the company that bought the "Swiss" Ilford plant. The
entire purpose, beyond cheap labor, is to use bamboo:
ultra-renewable, a weed. 

Bamboo's environmental questions will have to do with
bleaches (less than for wood or recycled cotton?), as
well as shipment from SEA. 

As many already know, bamboo laminate is replacing
hardwoods for flooring and much hardwood furniture.
It's tougher than maple or the Asian/African native
woods and is inherently beautiful. Environmental
questions include glue and the energy used by
factories.

Cotton is maximum-destructive, both in terms of soil
depletion and in terms of wasted croplands (should be
food...or perhaps hemp)...we like to think of cotton
as earth-conscious but that's wildly off base.
