Polio vaccines, eco brands, environment.

1) Green monkeys from Barbados are used to produce polio vaccine. Animal rights campaigners (BUAV) protest at the way the monkeys are mistreated, and the RSPCA wants an alternative vaccine if possible, but John Balu defends the present vaccine. 2) Detergents which wash "whiter than white" contain phosphates which leave rivers and ponds slimy green, covered in algae. The benefits of alternative zeolite detergents, however, may not be as clear as advertised. The "Phosphate Report" by Bryn Jones (Greenpeace), in a life-cycle analysis, finds little to choose, and phosphates could be removed from sewage - an end-of-cycle method. Sue Mayor, Richard Courtney and Brian Appleyard discuss this dilemma, and other issues such as global warming.
