which State no longer bans neonicotinoids, farm oversize, water retention mega-basins, and muzzles its biodiversity and food security agencies?

Answer: The French State, most sadly. Both chambers voted in favour of a U-turn in environmental and public health protections, aptly named Loi Duplomb (Lead Law!) that sees

  • Authorising anew neonicotinoïds, that are proven harmful to biodiversity and human health, which are nearly banned by the EU
  • Allowing agents to being simultaneously pesticide advisor and provider
  • Removing limitations on megafarm sizes and limiting public consultations on new projects
  • Promoting water storage projects (so-called megabasins) that increase water shortage and only benefit intensive agriculture
  • Introducing local supervision of the State Biodiversity Office (OFB) and imposing body cameras on its inspectors (some of whom were killed by farmers)
  • Increasing political control on the State Food Security Agency (ANSA) about its judgements on phytopharmaceutical products

The new law gets its name of a right-wing senator and farmer, with the heavy support of the agroindustrial lobby (FNSEA). And was voted with the support of the far-right, right and most of the central block parties, catering to their farming voters. Spray, baby, spray….!

red state – blue state – vaccinated state – unvaccinated state

The New York Times published an article demonstrating the partisan separation between US Democrats and Republicans by regression lines. As the one above, regressing the proportion of vaccinated on the proportion of Trump voters but no scale on the first axis. But no correction for age composition or population density. And the one below, plotted at the county level, which seems quite meaningless given the spread of red dots in Wyoming.

Still, there is a clear opposition between places (counties) that voted more than 70% Trump (representing 33M people) and those that voted more than 70% Biden (more than 58M people), even though county density, age composition, and earlier deaths from COVID should also be accounted for. But the vaccination rate also exhibits this opposition, with a 1.65 ratio between the first and last decile of the blue counties.
