Good News for Animals / Dobre vesti za životinje

            Dutch scientists have used stem cells to create strips of muscle tissue. The aim of the research is to develop a more efficient way of producing meat than rearing animals.
            Professor Post's group at Maastricht University in the Netherlands has grown small pieces of muscle about 2cm long, 1cm wide and about 1 mm thick. They resemble strips of calamari in appearance.
            Why use such high tech methods to produce meat when livestock production methods have done the job effectively for thousands of years?
            It is because most food scientists believe that current methods of food production are unsustainable. Some estimate that food production will have to double within the next 50 years to meet the requirements of a growing population. During this period, climate change, water shortages and greater urbanisation will make it more difficult to produce food. Keeping pace with demand for meat from Asia and Africa will be particularly hard as demand from these regions will shoot up as living standards rise. So, anything that stops more wild land being converted to agricultural land is a good thing. Lab-grown meat could eventually become more efficient than producing meat the old fashioned way.
            If the technology took off, it would reduce the number of animals that were factory farmed and slaughtered. There are definite environmental and animal welfare advantages of this high-tech approach over factory farming.


            Holandski naučnici su uspeli da naprave parče mesa uz pomoć stem ćelija. Cilj ovog istraživanja je da se pronađe i razvije način proizvodnje mesa koji bi bio efikasniji od uzgajanja životinja.
            Profesor Post sa Univerziteta u Mastrihtu u Holandiji, uspeo je da “uzgoji” parče mišićnog tkiva dugačkog 2, širokog 1 centimetar i debelog oko 1 milimetar. Vizuelno, ono podseća na meso ajkule.
            Čemu proizvodnja mesa uz pomoć visoke tehnologije kada smo hiljadama godina dobijali meso uzgajanjem stoke?
            Većina naučnika veruje da tradicionalne metode proizvodnje hrane uskoro neće biti održive.  Procenjuje se da će proizvodnja morati da se udvostruči u narednih 50 godina kako bi se zadovoljile potrebe rastućeg broja stanovnika na planeti. Tokom tog istog perioda, proizvodnja će biti otežana zbog klimatskih promena, nedostatka vode i sve veće urbanizacije. Porast potražnje mesa u Aziji i Africi će, zbog naglog porasta standarda, posebno otežati celu situaciju. Stoga, sve što može da utiče na zaustavljanje trenda pretvaranja divljine u poljoprivredno zemljište, može da ima samo pozitivan efekat. Meso koje se uzgaja u laboratorijama, pre ili kasnije će postati efikasnije od proizvodnje na tradicionalan način.
            Kad bi se tehnologija ubrzano razvijala u tom smeru, znatno bi se smanjio broj životinja koje se uzgajaju i kasape na farmama. Nema sumnje da bi ova tehnologija bila izuzetno značajna za očuvanje okoline i dobrobit životinja.
