For our planet’s sake
The UN’s “Livestock’s Long Shadow” report exposes the environmental devastation wreaked by animal production.
“The livestock sector emerges as one of the top two or three most significant contributors to the most serious environmental problems, on every scale from local to global.
... (It) may well be the leading player in the reduction of biodiversity, since it is the major driver of deforestation, as well as one of the leading drivers of land degradation, pollution, climate change, overfishing, sedimentation of coastal areas and facilitation of invasions by alien species.”

“The way that we breed animals for food is a threat to the planet. It pollutes our environment while consuming huge amounts of water, grain, petroleum, pesticides and drugs. The results are disastrous.”(2),(3)

(3) For figures on how much energy, grain, land etc is required to produce animal products, David Pimentel (Cornell University) has done a number of studies.
e.g. Table of energy input, from Pimentel D & Pimentel M (2003) "Sustainability of meat-based and plant-based diets and the environment" American Journal of Clinical Nutrition, vol 78(suppl) (660S-663S)
Grain consumption from same article:
Note that in Australia it is most common for sheep, dairy cows and beef cattle to be grazed on pasture, not fed exclusively on grain as in the US. (However pastures often need to be irrigated and fertilized etc. When good agricultural land is used for pasture it does not yield as much food as would be produced growing plant foods, and grazing on more fragile land can cause land degradation.)
Want to know the best way to reduce your water usage? Shorter showers? Not washing the car? How about reducing consumption of animal foods! Animal food production uses many times the amount of water used in plant food production. A simple way to save thousands of litres of water every week is to move towards a plant-based diet.

There are other estimates of water usage in agriculture. Estimates vary depending on criteria used in calculations. The trend is for plant food production to use much less water than animal foods. Other estimates are included below.
Figures in the following table were calculated under experimental conditions through measuring evapotranspiration.

Land clearing and Land degradation
Large areas of Australia’s forest and woodland vegetation systems have been cleared and degraded since European settlement, predominantly for agricultural activity(5). Currently 47% of Australia’s land surface is grazed, and just 3% cropped – and much of this 3% is growing feed for livestock(5).
(5) Australian Bureau of Statistics (2006) "Agriculture " in Year Book Australia 2006, Commonwealth of Australia, Canberra
The Year Book gives the following data for agricultural land use in Australia:
26.1 million ha were under crops at 30 June 2004, 367.6 million ha were being grazed, and 440.1 million ha were being used for agriculture in total which was 57.2% of the total Australian landmass. This meant 3.4% of Australia was cropped and 47.8% was being grazed. (The remainder supposedly left fallow)
The rich and the poor
Over a third of the world’s grain harvest is fed to livestock(6) in an inefficient conversion of nutritious plant-based food to animal product. Often livestock feed is grown in poor countries for the markets of the rich, while their own citizens go hungry.

“The West’s obsession with meat plays a direct role in starving the world’s poorest people. Meat is a killer in every sense of the word.”

Economics of a change to veganism
For a sector that contributes just 3% to the Australian economy(7), agriculture uses much more than its fair share of resources, mainly due to livestock. Clearly we need to have food regardless of the economy, but to guarantee ourselves a future we should revise how we produce our food. Since a healthy economy relies on healthy ecosystems, soon we may find we must change.
By encouraging more low-impact plant agriculture, and discouraging inefficient and wasteful livestock industries, we would do wonders for our environment while being unlikely to harm our economy. The health crisis would probably ease too, easing another economic burden. Those currently employed in the meat industries could be retrained to work in sustainable plant food agriculture and processing. It makes sense, it could be done. The only thing stopping us is our eating habit.

How can we justify this?
“ ... if one person is unkind to an animal it is considered to be cruelty, but where a lot of people are unkind to animals, especially in the name of commerce, the cruelty is condoned, and once large sums of money are at stake, will be defended to the last by otherwise intelligent people.”
Male chicks, of no economic value to the egg industry, are gassed or ground up alive(9). Other standard agricultural practices – almost always performed without anaesthesia – include castration, spaying, tail docking, debeaking, dehorning, tooth cutting, toe trimming, ear notching, nose ringing and branding(9),(10),(11),(12).
