Answer the question at the end by quoting:

Norman Ernest Borlaug (March 25, 1914 - September 12, 2009) was an American agronomist and humanitarian who led initiatives worldwide that contributed to the extensive increases in agricultural production termed the Green Revolution. Borlaug was awarded multiple honors for his work, including the Nobel Peace Prize, the Presidential Medal of Freedom and the Congressional Gold Medal. Borlaug received his B.Sc. in Forestry in 1937 and Ph.D. in plant pathology and genetics from the University of Minnesota in 1942.
Borlaug's name is nearly synonymous with the Green Revolution, against which many criticisms have been mounted over the decades by environmentalists and some nutritionalists. Throughout his years of research, Borlaug's programs often faced opposition by people who consider genetic crossbreeding to be unnatural or to have negative effects. Borlaug's work has been criticized for bringing large-scale monoculture, input-intensive farming techniques to countries that had previously relied on subsistence farming. These farming techniques often reap large profits for U.S. agribusiness and agrochemical corporations and have been criticized for widening social inequality in the countries owing to uneven food distribution while forcing a capitalist agenda of U.S. corporations onto countries that had undergone land reform.  Other concerns of his critics and critics of biotechnology in general include: that the construction of roads in populated third-world areas could lead to the destruction of wilderness; the crossing of genetic barriers; the inability of crops to fulfill all nutritional requirements; the decreased biodiversity from planting a small number of varieties; the environmental and economic effects of inorganic fertilizer and pesticides; the amount of herbicide sprayed on fields of herbicide-resistant crops.  Borlaug dismissed most claims of critics, but did take certain concerns seriously. He stated that his work has been "a change in the right direction, but it has not transformed the world into a Utopia". Of environmental lobbyists he stated, "some of the environmental lobbyists of the Western nations are the salt of the earth, but many of them are elitists. They've never experienced the physical sensation of hunger. They do their lobbying from comfortable office suites in Washington or Brussels. If they lived just one month amid the misery of the developing world, as I have for fifty years, they'd be crying out for tractors and fertilizer and irrigation canals and be outraged that fashionable elitists back home were trying to deny them these things".

Who were his biggest critics?

criticisms have been mounted over the decades by environmentalists and some nutritionalists.

IN: Isbell was born in Green Hill, Alabama, two miles from the Alabama/Tennessee state line, the son of interior designer mother Angela Hill Barnett and house painter Mike Isbell. Isbell's mother was only 17 years old (and his father 19 years old) when he was born and is the subject of a song, "Children of Children". Isbell's parents divorced, and he has two much younger half-siblings, Chantry Barnett and Emily Isbell. Isbell grew up in rural North Alabama.

Jason Isbell released his first solo album, Sirens of the Ditch, on July 10, 2007. In 2012, Isbell supported singer-songwriter Ryan Adams on his tour. Both played solo acoustic sets.  On June 11, 2013, Isbell released his fourth solo album, Southeastern. Produced by Dave Cobb and featuring accompanying vocals by Kim Richey and Isbell's wife, Amanda Shires, Southeastern received overwhelmingly positive critical reviews, earning a score of 87 on Metacritic. Southeastern led to Isbell's clean sweep of the 2014 Americana Music Awards. Southeastern won Album of the Year, Isbell was named Artist of the Year, and the song "Cover Me Up" was named Song of the Year. NPR rock critic Ken Tucker listed Southeastern at No. 1 on his top ten albums of 2013. Isbell's record received praise by artists like Bruce Springsteen and John Prine. Isbell's music video for the song "Traveling Alone" features the Jackson House, a historic home in Moulton, Alabama. In 2014, his song "Cover Me Up" was used as the weather for the Welcome to Night Vale episode "Visitor".  Isbell's fifth solo record, Something More Than Free, was released on July 17, 2015, on Southeastern Records. Dave Cobb produced, continuing the partnership created with Isbell on Southeastern. They recorded the album at Nashville's Sound Emporium studio with a full band. During the summer of 2015, Isbell was on a North American tour to promote the album, with four consecutive sold-out nights at the Ryman Auditorium in Nashville at the end of October. In April 2016, Isbell appeared on the BBC live-music show Later With Jools Holland, singing "The Life You Chose", one of the tracks from Something More Than Free.  Isbell said that compared to Southeastern, Something More Than Free has a feeling of celebration, which reflects his upcoming fatherhood and a forward-facing momentum. One track on the record, "To a Band I Loved", is a love-letter to the band Centro-Matic, a now defunct band from Denton, Texas, Isbell played with back in his Drive-By Truckers days.  Something More Than Free debuted at number 1 on Billboard Magazine's rock, folk and country record charts. Although Isbell had had critical success in the Americana genre, this was the first time he received such high ranking across genres. The album was well received, winning two Grammy awards for Best Americana Album and Best American Roots Song ("24 Frames"). On May 11, 2016, Isbell, a four-time winner, was nominated for three more Americana Music Honors & Awards: Album of the Year (Something More Than Free), Song of the Year ("24 Frames"), and Artist of the Year. He won the first two, while Chris Stapleton won Artist of the Year.
