Peat Free Compost

I stand very corrected! Thanks.

We use peat for storing roots - but it just gets re-used and is probably nothing to the damage heating our house causes the environment,

Garden use won't release CO2 -
A lot of our peat bogs have gone but so have many other natural habitats - forests and wetlands for agriculture,

garden use is a hugh reason for destroying peat bogs therefore is responsible for the CO2 release caused.
It is a carbon sink and one of the problems for example in Finland where it is used as a fossil fuel is that farmed areas are used as forest instead of leaving them to recover,the carbon absorbed by the tree  nowhere  offsets that released in the mechanical stripping in the first place.
OK tropical forests sound more romantic a thing to saved but the peat bogs we still have need preserving too.
For those who find they can`t grow without peat then please note that we didn`t use it much before the 1950s or check out  the Kew Gardens web site as they are now growing without peat
