na exposição de motivos diz-se que o haarp (high frequency active auroral research project) , programa de investigação de alta frequência auroral activa, é um programa de investigação de natureza claramente militar, da chamada « guerra das estrelas », que deve ser considerado como seriamente nocivo para o ambiente e pode ter efeitos incalculáveis para a vida humana, que é contestável do ponto de vista jurídico e pode mesmo constituir uma violação do direito internacional.
in the explanatory statement, haarp -the high frequency active auroral research project -is said to be a military research project on the lines of 'star wars'which is environmentally damaging, has an unknown effect on people 's lives and is legally questionable and probably in breach of international law.
