This report in FR24 cites the director of research at France's National Institute of Health and Medical Research, Inserm, about the damaging effects of an insecticide used in the French West Indies. The result is that there are violent protests against the vaccine mandate being implemented in the French West Indies.
The FR24 report says that about a third of the marine coastline, and a third of agricultural land and land for breeding, in the West Indies islands of Guadeloupe and Martinique is polluted by the insecticide chlordecone. The insecticide was first used in banana plantations in the French West Indies against banana insects. The insecticide has now contaminated the soil and groundwater.
