 as a co-founder of Greenpeace in the UK and a member of the first board of Greenpeace International, I am deeply saddened by the organisation's decision to spend ? 14m on a ship when it already has perfectly serviceable vessels in which to operate ("The Warrior returns", Magazine, last week). Largely due to the sinking of the Rainbow Warrior in 1985, Greenpeace has enjoyed a massive growth in income and support in the last 25 years.  Yet it seems so far removed from reality that it chooses now, in these times of economic and political strife, to plough ? 14m not into a sustainable energy demonstration project, nor into a joint effort with a development charity to unite the causes of poverty and environment but into a new ship which will be as alien to the peoples of the amazon as Greenpeace is in danger of becoming to a generation hoping for it to realise its true potential.
