Unglaublich‼️Schon wieder reißt die EVP die Brandmauer ein – diesmal beim Waldschutz. Statt Kompromisse mit der Mitte zu suchen, peitscht sie ihre Maximalposition mit extrem Rechten durch‼️ Das schwächt das EU-Entwaldungsgesetz, bestraft vorbildliche Unternehmen & gefährdet bis zu 150.000 Hektar Wald.
