Ferti-Facts: Nitrogen - A Change in Tradition


Daniel Rutherford discovered the existence of nitrogen by first depleting oxygen from air. He accomplished this by asphyxiating a mouse in a closed jar, burning a candle until it went out in the jar, and burning phosphorus until it would not burn. The remaining gas was passed through a carbon dioxide absorbing solution.     The remaining gas (which is now almost pure nitrogen gas) did not support the burning of a candle or life of a mouse. He referred to this gas as noxious or phlogisticated air (Phlogiston was a postulated element that was released from combustible bodies when burned).

The Environmental Defense Fund opened an office near Walmart's headquarters in Bentonville, Ark., 10 years ago. It was part of a carefully plotted strategy to persuade the giant retailer that going green could be good for business. If it worked, it certainly could be good for the planet — Walmart's revenues are bigger than the entire economy of most countries.

"We really saw that working with companies could be transformative at a scale that was pretty unmatched," says Suzy Friedman, a senior director at EDF.

If you're looking for evidence that the strategy is working, there's this: Last year, Walmart unveiled Project Gigaton, a plan to reduce emissions of greenhouse gases by a billion tons of carbon between now and 2030. That's almost as much carbon as what's released from the country's entire fleet of passenger cars and trucks in a year.

The cuts will come from the company's suppliers: the vast galaxy of companies that make the products it sells.
