Nitrogen levels in the soil, water and atmosphere have increased fivefold globally in the past 60 years – largely due to human activities in the agricultural sector, according to a new study. Too much nitrogen can affect human health, reduce biodiversity and amplify global warming.
"Just as carbon fueled the Industrial Revolution, nitrogen has fueled an Agricultural Revolution," the study authors wrote. "The use of synthetic nitrogen fertilizers and the cultivation of nitrogen-fixing crops both expanded exponentially during the last century, with most of the increase occurring after 1960."
The National Labor Relations Board has issued a complaint against Tesla following allegations that it was intimidating employees who wanted to unionize. This follows four charges filed in February by the United Automobile Workers against Tesla for allegedly surveilling and coercing workers who attempted to distribute information about the union drive.
Details: According to the NLRB's complaint, obtained by Buzzfeed, Tesla security guards asked those workers to produce IDs and to leave the premises. It also mentions Tesla's policy prohibiting workers from discussing their work environment with the media, sharing photos on social media, and forwarding work emails to a personal account.
Tesla dismisses the allegations as baseless. A hearing in front of a NLRB administrative judge is scheduled for Nov. 14.
