This episode of Greenhouse looks at a new report by Reuters that says the 500 biggest companies in the world have actually increased their Co2 emissions since 2010. Tony Dokoupil also talks to Greenpeace about why the internet is pollution to the planet and why the “drought shaming” social media campaign is not really working. Plus, Dokoupil explains what humans are doing to the world’s fish and why the fear of GMOs is unfounded. Greenhouse airs Thursdays at 12pm ET on Shift.May 29, 2015
