The Green Party electromagnetic policy includes "Minimise exposure to electromagnetic radiation especially for children and pregnant women."
Electromagnetic radiation includes visible light.
So the Greens presumably want kids keep indoors during the day, and at night, keep the lights out.
Oh and if that isn't good enough for you, it would include wifi internet, it would include all computer monitors, TV screens, and even radios - they all emit electromagnetic radiation.
Do you still trust the Greens on anything scientific?
