...the product. Worldwide, agencies that oversee the safety of GE crops regulate the process, not the product, bypassing consumers to make market choices and pre-empting the development of new products, especially non-commodity specialty crops ( Bradford, Van Deynze, Gutterson, Parrott, & Strauss, 2005 ; Miller & Bradford, 2010 ). While some may be alarmed that science has developed the ability to bioengineer crop plants, humans, as engineers, have changed the natural world to an extent that every ecosystem on Earth has been altered. The degradation of...

...soil quality and reduces soil erosion ( Nielsen & Calderon, 2011 ). Crop residue cover in fallow land serves as an organic mulch that increases the moisture contents in soil and reduces evaporation losses and provides shelter for soil against wind and water erosion ( Smart & Bradford, 1999 ; Zribi, Aragüés, Medina, & Faci, 2015 ). Fallow fields covered with residue (80%–90%) protects soil from erosion ( Kline, 2000 ) by acting as barrier against wind and high-intensity rainfall, thus increasing water infiltration, reducing soil evaporation losses (...
