Beyond coal and environmentally friendly pot

58:01

Thursday’s Greenhouse takes a look at the “badass” women of science and how the new GE smart street lights could help cities. Tony Dokoupil has a conversation with the executive director of the Sierra Club about their new campaign on coal. Plus, we show you two military groups whose acts of heroism are unknown to the public. Lastly, Dokoupil talks to the owners of “Happy Day Farms” who are growing pot in a sustainable way. Greenhouse airs Thursdays at 12pm ET on Shift.
