From the Evening Standard, Tuesday, November 7, 2000
DAVID BELLAMY is backing an international plan to sue socalled climate -change 'criminals', including governments and industries, that block moves to halt global warming.
Environmentalists, following the example of the anti-tobacco lobby, which wants the cigarette industry to pay damages for smoking-related diseases, are launching a worldwide fighting fund to pay for legal action against organisations that harm the planet.
Money from successful cases could go towards rebuilding work following an environmental disaster.
Dr Bellamy said that the scientific evidence that pollution was contributing to many of the world's natural disasters was incontrovertible.
