INTRODUCTIONThe essay incorporates the various sources of greenhouse effect and static governmentmeasurement to reduce the same in Australia. The MLA has been taking initiative to reducecarbon emissions from ruminants who are though major source of food production in Australia.They contribute around 6 billion tons of greenhouses gases each year in Australia. The wastegenerated by ruminants produces methane and nitrous oxide which are the largest contributorsfor warming earth's surface. The essay will provide an overview about the livestock and itscontribution towards greenhouse effect and efficiency of Australian market. It will incorporatepolicies and procedures to reduce gas emissions from livestock.Australian livestock digestion contributes generously to greenhouse gas emissions. AsAustralia is amongst the second in exporting of wool and red meat they need to maintainlivestock by feeding extensively providing tropical grasses and woodlands which are inabundance (Smith and et.al., 2018). It has been estimated that livestock production is growing ata faster speed than agriculture thus producing more and more greenhouse gas. Methane andnitrous oxide is produced from livestock digestion system and has reached 50% of overallemissions in Australia.It has been researched that total 80 Mt of methane is produced globally from ruminantsboth wild and domestic (Frappart and et.al., 2018). Both methane and nitrous oxide represents aloss of energy and decrease of nitrogen capture for plant growth. CH4 or methane contributes to11% of national greenhouse gas emissions in Australia which comes from beef, dairy cattle andsheep. The methane is produces in the rumen of these animals which is the first stomach ofruminants and helps in fermentation (Sankar and et.al.2018). Methane plays a critical role inremoving the hydrogen produced in microbial fermentation in the large fore-stomach (rumen) ofthese animals, allowing efficient digestion, growth and performance. MLA has been involved inreducing methane emission using government programs such as Carbon Farming Futures andRELR program.Category of LivestockMethane Emission (in Mt)Beef Cattle36.6Sheep13.6Dairy Cattle6.8Feedlot Cattle2.11
Others0.24The above table depicts various category of livestock and emission of Methane gas from theirdigestion process in Australia in the year 2008 (Frappart and et.al., 2018). It is estimated that the global production of meat and dairy products will increase by theend of 2020 enhancing consumption capacity of people in developing countries. The Australianlivestock industry have a huge potential to enhance its operations so as to make profits but needsto take a strict control over controlling of harmful gases in the environment. The Australiangovernment needs to take sustainable and environment production of meat and dairy products todecrease the essence of greenhouse effect (Sankar and et.al., 2018).(Source: Sankar and et.al., 2018)Australia has been amongst the highest producer of methane emission all over the globe.Thus it requires to form strategies in order to reduce carbon footprint so as to reduce methaneand other harmful gas emission (Sergeev Sablon and Little, 2018). The graph depicts theincreasing rate of emission with the changing years has increased in Australia as compared toother parts of the world. Australia has generated huge tonnes of red meat for all parts of theglobe and thus contributed generously in the emission of harmful gases by the ruminants andtheir digestive process.The use of red meat and cattle products in Australia has seen a major change in last fewyears which impact its overall equilibrium market efficiency. The cost-benefit analysis ofAustralian market weighs the consequences of carbon emissions and the cost related to stabilizeits impact on the country. Policy needs to be formulated in order to bring benefits which are2
