Eat Less Meat to Save Ourselves.
A report has been released by the U.N., in which it is urged that we reduce consumption of meat and dairy products as a means to mitigate climate change, hunger and fuel poverty It is stressed that food, transportation and housing must be made more sustainable if we seriously intend to ameliorate biodiversity loss and climate change, and as a matter of urgency. Some 30% of global CO2 emissions is a result of internationally traded goods, while the mining sector uses 7% of the world’s energy: a fraction that is expected to increase in line with “growth”, which has serious connotations regarding international policy. A doubling of income is predicted to cause an 81% increase in CO2 emissions, which is an alarming prospect in the context of the rising population, predicted to be over 9 billion by 2050. 70% of all the world’s freshwater consumption is taken by agriculture, which also accounts for 38% of the total use of land, and 14% of global greenhouse gas emissions. It has been estimated that it will be necessary to increase food production by 70% in 2050 if the population of the world is to be fed, but its expected increase from 7.3 billion now to perhaps 9.6 billion in 2050 will overwhelm any efficiency gains in agriculture. The production of animal products is particularly demanding in terms of land for grazing animals, and water, and a rising global middle class which is increasingly meat-hungry.
The above 70% increase in food production assumes that the western diet will spread to the Global South, with no reduction in consumption by the northern nations. 30-40% of cereals are presently fed to animals, which could rise to 50% if levels of meat and dairy consumption increase as predicted. It has been reckonedthat 3.5 billion additional people could be fed if all cereals were given over for human consumption.
