Nitin Sawhney and Bobby Friction are among the 20+ artists who allowed themselves to get dumped on by agricultural and horticultural food products as a way to bring voice to the "Make Trade Fair" movement. Make Trade Fair is part of the Global Call to Action Against Poverty and as their website states:
The Global Call to Action against Poverty is a worldwide alliance committed to making world leaders live up to their promises, and to making a breakthrough on poverty in 2005.
Oxfam's Make Trade Fair Campaign is part of this global movement for change - working with others to demand trade justice so that trade can be part of the solution to poverty - not part of the problem.
