Clean Air Act (1 janv. 1970 – 31 déc. 1970)
Description:
This is an act that regulates emissions and set national standards for air pollution. This is significant because it gave us a clearer definition of what the threshold for environmental harm is, so we have been able to tackle the right sources of pollution and get our emissions down as efficiently as possible.Ajouté au bande de temps:
