A review of a number of papers which gives Bt crops a more or less clean bill of health but does conclude that more investigation is needed before widespread commercialisation. Which is odd given that Bt crops are already widely used in US and Asia – especially in Maize and Cotton.
The problem with reviews of papers is that if the papers are flawed the review simply accepts and multiplies the flaws. Crap in and a multiple of crap out. Which is what seems to have happened here as the authors do not acknowledge the mounting criticism of research trials in this area.
