La polinización se desplomó 31% en campos contaminados

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 12 April 202212 April 2022

Los niveles de contaminación del aire por debajo de los límites “seguros” (y más bajos que los que comúnmente se encuentran en las ciudades) llevaron a una disminución significativa de la polinización de hasta por 10 insectos comunes.
