A thing is right when it tends to preserve the integrity, stability and beauty of the biotic community. It is wrong when it tends otherwise. 1920 Solidarity is strength. Although there is no national organisation, there is a high level of group co-operation. Family outings' to other groups' campaigns happen regularly.
Groups also carry out solidarity actions for each other.
An example is Wimpey Construction who found this out to their cost. As well as dealing with the protesters in Glasgow, they had to face occupations of their regional offices, a number of their showhouses being squatted and other construction sites being invaded. For example, when other green groups respond to a new road project by coming up with an alternative route or tunnel, we campaign for no road at all. When other groups have backed down to court injunctions or police threats, we refuse to be intimidated into inaction. The Struggle is Global.
