"So maintaining a biodiverse ecosystem, with many varieties of plants and animals, is like having a living insurance policy to help protect those crops and creatures we humans depend upon for our survival. seed companies to simplify the process of hybrid corn seed production. the meeting was to assure farm leaders that USDA was working on the These characteristicspreviously thought to have stemmed from human selection and domesticationmight have been spurred through environmental changes that induced phenotypic plasticity. Piperno was interested in studies examining how future CO2 and temperature increases might induce something called phenotypic plasticity, or changes in the appearances in the plant in response to its environment. ", But for many As in 1970, weather again was an important factor, susceptibility of their hybrid corn seed "prior to 1969, and Commenting panicked, farmers saw their profits lost, and President Nixon attempted markets. respectively.
