As well as the reduction in biodiversity which could result from this, there have been allegations of a conflict of interest at the heart of the plans:
(I have condensed this, but it can be found here )"Madame Isabelle Clément-Nissou, sent by the French Government to DG SANCO, is now a ‘Policy Officer on Seed and Reproductive Material’ working to support the drafting of future legislation on the Marketing of Seed and Plant Propagating Material.
She was actually sent on behalf of GNIS (Groupement National Interprofessionnel des Semences) Despite its public role, this is a privately funded lobby group run by and staunchly defending the interests of the seed industry. The fact that this organisation has been entrusted to a public service does not make it a “national, regional or local public administration or an IGO”.
The fact that France has largely given away the direction of its seed policy to industry is problematic, but this situation should not be allowed to negatively influence the drafting of EU legislation."
