¿Durante cuál época de la historia de la humanidad piensas que se ha producido mayor contaminación del medioambiente?

Unos años antes, en 1948, la severa contaminación industrial del aire creó una niebla tóxica mortal que asfixió a 20 personas en Donora, Pensilvania, y enfermó a 7.000 más. La lluvia ácida, descubierta por primera vez en la década de 1850, fue otro problema derivado de las plantas de carbón.
