matson: all organisms need a lot of nitrogen. plants and people and all different kinds of animals and microorganisms use nitrogen in our cells, and we need a lot of it. and of course, we are literally bathed in it. the atmosphere is 78% dinitrogen so there should be plenty, right? but the problem is that most organisms don't have access to that dinitrogen in the atmosphere. they can't use it. they can't get at it. narrator: while certain bacteria can convert this nitrogen into forms that other organisms can use, for many crops more nitrogen is still required. and nitrogen fertilizer allows plants to receive the much-needed nutrient that they lack. the use of fertilizer dramatically increased during the green revolution, where, from the 1940s through the 1960s, new seed varieties were introduced in many developing nations helping avoid widespread famine. dr. naylor: the green revolution is just adapting crop varieties to have much higher yields on a limited land base. and the key factor was new seeds for plant types, and these pl
