Genetically engineered animals: From lab to factory farm
This report from environmental NGO Friends of the Earth US outlines the health, environmental, ethical and consumer concerns associated with research into genetically engineered livestock. It notes that gene editing can lead to unintended effects, such as unintended modification of portions of DNA, enlarged tongues in rabbits, extra vertebrae in pigs, and novel proteins produced in error (which could result in allergic reactions).
North America is the northern subcontinent of the Americas covering about 16.5% of the Earth's land area. This large continent has a range of climates spanning Greenland’s permanent ice sheet and the dry deserts of Arizona. Both Canada and the USA are major food producers and some of the largest food exporters in the world. Industrial farms are the norm in North America, with high yields relative to other regions and only 2% of the population involved in agriculture.
