A kangaroo walks into a bar and orders a
beer.The bartender figures that a kangaroo
probably isn'tvery economically aware, and
charges him 50 !The bartender curiously
remarks, "You know, we don't get too many
kangaroos in here."The kangaroo replies, "At 50
a beer.. no wonder."

The problem
Meet the world's top destroyer of the
environment. It is not the car, or the plane, or
even George Bush it is the cow.

Cows???

• Cows may the biggest single source of methane
• CH4 is 23 times more potent than CO2 when it
  comes to global warming.
• The average dairy cow is capable of producing up
  to 500 litres of the gas every day!!!!
• mostly through belching.
• The methane belched also represents a waste of
  feed of anything from 3.5 to 7.5 per cent.

5
Seriously?

• According to a United Nations Report, cow
  "emissions" are the greatest threat to the
  environment.
• The world's 1.5 billion cattle are responsible
  for 18 of the greenhouse gases that cause
  global warming.
• That is more than cars, planes and all other
  forms of transport put together.
• The 400-page report (lets kill a few trees!) by
  the Food and Agricultural Organization,
  Livestock's Long Shadow, states
• Cow farts account for 9 of all carbon dioxide
  emissions.
• Their "wind" and manure account for more than 33
  of methane.
• Cow farts produce 100 other polluting gases
  including ammonia, one of the major causes of
  acid rain.
• Sheep are also a problem!

6
This is a problem?

• Experts claim cows are responsible for about 3
  of Britain's greenhouse gases
• New Zealand's cattle and sheep produce the
  equivalent of about 24 million tonnes of carbon
  dioxide a year, about a third of national
  emissions of greenhouse gases
• Fourteen percent of emissions from all sources in
  Australia is from enteric methane from cattle and
  sheep," said Athol Klieve, a senior research
  scientist with the Queensland state government

7
What to do?

• Breed methane-free sheep
• New Zealand and France claim to have bred methane
  free sheep by conventional methods
• Dr Keith Joblin, AgResearch Ltd and others!
• Genetic engineering?

What to do?

• Change the feed.
• garlic compounds naturally attack the organisms
  in cows guts that produce methane.
• will it taint the flavor of milk or meat?
• initial results from the start of the three-year
  study show that feed containing garlic could cut
  the amount of gas produced by up to 50.
• Department for Food, the Environment and Rural
  Affairs (Defra) said recent research suggested
  that "substantial methane reductions" could be
  achieved by changes to animals' feed.

9
What to do?

• Take a pill!
• German scientists have invented a pill to cut
  bovine burping.
• The fist-sized plant-based pill, combined with a
  special diet and strict feeding times, is meant
  to reduce the methane
• Use the methane to produce glucose instead?
• University of Hohenheim in Stuttgart

10
What to do?

• Introduce methane consuming bacteria to the rumen
• 6000-year-old Lake Pavin has an anaerobic zone in
  the bottom 1/3 of its 92m depth
• deepest zone contains methane, but none reaches
  the surface
• Dr Gerard Fonty a microbe living on the methane
  produced in the sediment at the lake bottom
• Bacteria can be grown at room temp maybe will
  grow in sheep?

11
What to do?

• Develop vaccines that stimulate antibodies which
  restrict the activity of methane-producing
  organisms in the rumen
• Find out why one cow produces more methane than
  another
• In Aberystwyth, researchers are measuring the
  amount of methane and nitrogen produced by sheep
  by housing them in a plastic portable tent.

12
What to do?

• Introduce bacteria that will not produce methane
  from kangaroos!
• Thanks to special bacteria in their stomachs,
  kangaroo flatulence contains no methane
• Scientists want to transfer that bacteria to
  cattle and sheep
• Researchers say the bacteria also makes the
  digestive process much more efficient and could
  potentially save millions of dollars in feed
  costs for farmers.
• "Not only would they not produce the methane,
  they would actually get something like 10 to 15
  percent more energy out of the feed they are
  eating," said Klieve.

Eat em!
Kangaroo meat is very low in fat and contains
almost no cholesterol. Meat is not vaccinated
and is free range. AND..

26
And Finally

• What kind of animal has the highest worldwide
  output of flatus?
• The termite!
• Because of their diet and digestive processes
  (with more than the usual microbial assistance),
  they produce as much methane as human industry.
• Termite farts are believed to be a major
  contributor towards global warming.  

27
The End

• Is it true that cow farts contribute to global
  warming?
•     Recent research has shown that most methane
  produced by cows and sheep emerges from the mouth
  rather than the anus. So one could more
  accurately say that cow and sheep belches are
  contributing to global warming.
