Large scale meat production is resulting in deforestation, polluted waterways and a host of other adverse environmental effects. Alternative meat products are potentially healthier and more efficient alternative to conventional meat, with lower use of land, water and agricultural inputs. One production approach, often called substitute meat or meat analog, involves the conversion of non-animal biomass to have the characteristics of actual meat. Another approach, often called cultured meat, cellular meat or in-vitro meat, involves the managed growth of actual animal cells. An affordable, sustainable alternative meat production system could satisfy our population’s growing meat demand with reduced environmental impacts and potentially increased nutritional value.
