Be a vegetarian to help save the world

Methane, the green house gas.

Methane is 21 times more potent at trapping heat than carbon dioxide, the most abundant global warming gas. Much the methane, also called natural gas, is coming from livestock, including manure, belches, and flatulence, as well as leaks from refining and drilling for oil and gas.

In 2008, it is estimated that U.S. poured 49 million tons of methane into the air. That means U.S. methane emissions trapped about as much heat as all the carbon dioxide pollution coming from cars, trucks, and planes in the country in 6 months.

Farm Animal is the main Methane source.

Cattle generate twice as much methane as the EPA supposed, according to a report published by Harvard University. About 90 million cattle in US feedlots are the country's largest source of methane from anthropogenic (human-caused) emissions, the Environmental Protection Agency estimates.

In Texas, Oklahoma, and Kansas, anthropogenic methane emissions from all sources were 2.7 times greater than believed, making up 24% of the nation's emissions. This was found a study published in the Proceedings of the National Academy of Sciences.

According to the report, anthropogenic methane emissions account for 50~65% of the global methane "budget", the largest portion of which comes from cattle. The natural-gas industry is the next largest source, followed by fermentation in landfills and then coal mining.

Humanities desire for meat leads us to breed and eat  tens of billion farm animals per year, a figure so large and has absolutely devastating effects on the planet and also our health.

Why do we need to be a vegetarian?

The fastest way to halt global warming by curbing global greenhouse gas emissions  is for all the people in the world to become vegetarian. You don't need to be a full-time vegetarian, though that would certainly be more helpful. You can just start with one vegetarian meal a week, then twice a week, and so on. Because very bit help!

The food that we already grow to feed the animals (mostly soy and corn) could be used to feed the humans directly, which would create a huge surplus of food, since livestock does not return the same amount of protein that we feed it. Cows for instance return only about 8%. And with 40~60% of the worlds grains being fed to cattle and other animals.

Less Grain for animal, more for mankind!
Around 760 million tonnes of grain would be used to feed chickens, pigs and other farmed animals, she said - more than seven times the amount used to produce biofuels; and it take up to 16 pounds of precious grain to produce just 1 pound of meat. This would free up massive amounts of food to feed to humans, thus eliminating global hunger.

Billions of dollars would be saved on health care each year, as heart disease and colon cancer (two of the Western World's biggest killers) would become almost non-existent, and humans in general would live better lives.

If only we could stop.

If the world stopped eating meat, we could also stop clearing land (the Amazon for example), which would also help to alleviate a whole host of other problems that the planet faces. Global deforestation will be slowed, or even stopped.

People would have better health, countries would have more money, the environment would be cleaner, there would be less natural disasters, global hunger could be eradicated, more clean water for all. (Animal farming use a lots of water)

We should encourage more Nuclear Power R&D and not avoiding it.

Would you dare drive your family with a 60 year-old car to a field trip?
This is what we ARE doing with our (2nd generation) Uranium Nuclear Reactor... which is very unsafe, meltdown-prone, create lots of nuclear waste and expensive!
( its "other" MAIN purpose is to produce nuclear bomb raw material!!!
 Uranium Reactor was DESIGN to produce nuclear BOMB raw material !!! )

Wind, Wave, Geo, Solar, Bio, hydro are all good, but these green energy will not be enough for us to cut significant amount of global carbon while providing the ever-increasing global energy demand...

However, with (4th generation) Thorium Nuclear Reactor would potentially solve ALL our problems!!
Fail-Safe, vastly cheaper, almost impossible to meltdown, and much much harder to make a bomb with it!

NASA scientist : With just 2% of the world's power generated by non-hydropower renewables like solar and wind, only a rapid expansion of nuclear power can realistically slash use of coal and other fossil fuels within the next 30 years. But the public's emotional, "quasi-religious" rejection of nuclear power is holding back much-needed R&D that would bring advanced nuclear technologies into the energy mix, that would largely solve environmental and safety problems that have spooked the public.
WE need to be braver and bolder about studying ADVANCED nuclear energy and communicating it publicly.

FYI, With the recent nuclear accidents, the global nuclear power industry has seen deterioration over recent years, but nevertheless, the industry is expected to expand and post a strong growth rate. Having revenues of nearly USD 140 Billion in 2013, there are over 400 civil nuclear power reactors in operation around the world today, with the US accounting for nearly one third of the world's nuclear electricity.

Eating less meat to slow climate change!

Gases from animals destined for dinner plates account for nearly a quarter of all methane emissions worldwide.

Eating less meat could help slow global warming by reducing the number of livestock and thereby decreasing the amount of methane flatulence from the animals.

Livestock – predominantly cattle – are responsible for an astonishing proportion of global warming gases - 18 per cent of all emissions - which is more greenhouse gas emissions than all the transport on earth – planes, trains, cars......

Most deforested land is used for pasture and the UN reckons the carbon released in the process takes the carbon cost of livestock up to the equivalent of 2.7 billion tonnes of carbon dioxide.

1.5 billion head of cattle on the planet and 7 billion sheep. They, together with the more modest emissions of other farm animals, produce 37% of global methane emissions which adds up to the equivalent of another 2.2 billion tonnes of carbon dioxide a year.

Factor in the effects of another global warming gas - nitrous oxide, which is way more potent than even methane with 296 times the global warming power of carbon dioxide. 65% of human related emissions of nitrous oxide are from the nitrogen in animal manure. That accounts for the equivalent of another 2.2 billion tonnes of carbon dioxide a year.

Add the effects of the three gases associated with farming animals and you get total emissions equivalent to 7.1 billion tonnes of carbon dioxide a year. According to the UN report we humans are responsible for a total of the equivalent of 40 billion tonnes of carbon dioxide a year. That’s how we got that incredible figure of 18 per cent of total emissions.


In a special energy and health series of the medical journal The Lancet, experts said people should eat fewer steaks and hamburgers. Reducing global red meat consumption by 10 percent, they said, would cut the gases emitted by cows, sheep and goats that contribute to global warming.

If people knew that they were threatening the environment by eating more meat, they might think twice before ordering a burger.

On average, in developed countries, people typically eat about 224 grams per day. But in Africa, most people only get about 31 grams a day. If the global average were 90 grams per day, that would prevent the levels of gases from speeding up climate change.

Eating less red meat would also improve health in general. Dr. John Powles, a public health expert at Cambridge University, one of the study's authors and his co-authors estimate that reducing meat consumption would reduce the numbers of people with heart disease and cancer. One study has estimated that the risk of colorectal cancer drops by about a third for every 100 grams of red meat that is cut out of your diet.

Eating less meat would also help stop the obesity epidemic in developed countries.

So why is the meat we eat so polluting?

Well, first of all we need to get a sense of scale. 70% of all agricultural land is used to raise animals – that’s a third of the land surface of the entire planet. What’s more, over 30% of all cereal production goes to feed those animals.

Ruminant animals like cows and sheep produce a lot of methane as they digest their food. And methane is a powerful greenhouse gas – 23 times as powerful as carbon dioxide in trapping heat to make the earth warmer.

Furthermore, on average, it takes 1,790 litres of water to grow 1kg of wheat compared with 9,680 litres of water for 1kg of beef.

Western diets, which depend largely on meat, are really putting great pressures on the environment. Meat-eaters consume the equivalent of about 5,000 litres [1,100 gallons] of water a day compared to the 1,000-2,000 litres used by people on vegetarian diets in developing countries.

So, the conclusion, eat less meat, help reduce the greenhouse gases, slowing down the global warming, conserve more water, and more importantly, become healthier!

That's why it's good to have 3 million vegetarians in UK. Just hope more people can cut their meat diet, if not totally... :)

Prenatal Omega-3 to boost baby brain!

Omega-3 may boost baby’s brainpower!

NEW YORK (Reuters Health) - Children whose mothers get enough omega-3 fatty acid during pregnancy may have sharper problem-solving skills in infancy, a small study suggests.

Researchers found that 9-month-olds whose mothers had eaten DHA-fortified bars during pregnancy performed better on a test of problem-solving abilities than infants whose mothers had not added DHA to their diets.

DHA, or docosahexaenoic acid, is one of the major omega-3 fatty acids. Because of the fat’s vital role in brain development, experts recommend that pregnant women get 300 milligrams (mg) of DHA each day.

However, research shows that few U.S. women meet this goal.

The new findings, published in the American Journal of Clinical Nutrition, suggest that women who do get adequate DHA may aid their infants’ cognitive abilities.

The study included 29 women in their 24th week of pregnancy. Half were randomly assigned to eat a cereal bar supplemented with 300 mg of DHA from fish oil, while the rest were given a bar with added corn oil to serve as a comparison. On average, the women ate five bars per week.

Their babies underwent standard tests of infant problem-solving and memory at the age of 9 months. The problem-solving task tested the infants’ ability to retrieve a toy that was covered by a cloth.

In general, the researchers found, babies in the DHA group performed better on the test than those in the comparison group. There was no difference between the two groups on the memory test.

It’s not entirely clear what the better problem-solving performance at 9 months of age will mean later in life. However, other studies have found that DHA supplements during pregnancy seem to offer a “developmental advantage” later in childhood as well, Dr. Carol J. Lammi-Keefe, a co-author on the current study, told Reuters Health.

One study found that giving women fish oil during pregnancy and during the first few months of breastfeeding seemed to boost their children’s IQ scores at age 4.

“DHA during pregnancy has benefits for infant neural development, and most pregnant women can benefit from increasing the intake of DHA in their diets,” said Lammi-Keefe, of Louisiana State University in Baton Rouge.

Women can go a “long way” toward getting 300 mg of DHA per day.

Pregnant and breastfeeding women should avoid certain fatty fish, however, because they could have high mercury levels. These include shark, swordfish, king mackerel and tile fish.

Alpha-linolenic acid (ALA) is what is known as an omega 3 fat, and is a precursor of the longer chain omega 3 fats eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) - ie EPA and to a lesser extent DHA can be made in the body from ALA.

Sources of Omega 3 Fats
Flaxseed oil : 1 tablespoon (14g) :
provides 8.0g of ALA and insignificant levels of LA

Flaxseed, ground : 1 tablespoon (24g) :
provides 3.8g of ALA

Rape Seed oil : 1 tablespoon (14g) :
provides 1.6g of ALA and only twice as much LA

Walnuts : 1 oz (28g) :
provides 2.6g of ALA but also four times as much LA

Tofu : 4.5oz (126g) :
provides 0.7g of ALA but also seven times as much LA

It is also important to ensure that the intake of LA is not too high compared with ALA since a higher intake of LA interferes with the process in which the human body converts ALA into the even more beneficial EPA and DHA, so a LA to ALA ratio of around 4 to 1 or slightly lower is considered to be the optimum.
