the green partys other policies area bit crud but what with cannabis been legalised it could be used on a larger scale to combat climate change.
1 acre of hemp produces as much paper as 4 acres of trees, can be used to make bio fuels, organic plastics which are bio-degradeable unlike our more prominent oil based plastics, as well as the stems which are able to be made into fabrics for clothes as well as ropes.
also at the end of the day if it was legalised and the goverment experimented on it more they would be able to make it that strong that the main of the population of britain wouldnt be able to get their asses out of their chairs after their first joint when they got back from work.which happens in quite a few households in britain i imagine.
