The redneck strike again.

[Confused Ape]

It means that in some part of the planet people eat this in other part
eat that but there is no evidence that those who eat meat did eat
meat for a long span of time.
It could be that they eat meat until the normal food was available

You still haven't explained how people living in the Artic survived for generations on a diet which was mostly meat because there's very little plant food available there. You also haven't explained why the Inuit's health deteriorated when they stopped eating wild animal meat and went over to factory farmed meat.

Most of my veg. friend don't take any b12 supplement and
they are in excellent health.
Some of them are old and have been veg. for long long time.

Fortified Foods

There are many vegan foods fortified with B12. They include non-dairy milks, meat substitutes, breakfast cereals, and one type of nutritional yeast.

Brewer's and Nutritional Yeasts

Brewer's and nutritional yeasts do not contain B12 unless they are fortified with it.

If your friends are eating enough food which has been fortified with Vitamin B12 they won't need to take supplements. Vegans who don't eat enough fortified food are asking for trouble if they don't take a supplement. From the Vegan Health site again - Vitamin B12 - Are You Getting It?

You keep on jumping to conclusion very quickly (as usual).
I didn't say that we shouldn't worry about palm oil.
I instead said that considering that veg burgers are eaten by
very few people then it wan't cause big changes.
That does not mean that it want cause any change at all.

Vegetarianism By Country

Millions of people around the world are vegetarians and the number is increasing in many countries. Palm oil isn't just used in meat substitutes, either, because many food products labelled suitable for vegetarians are eaten by the rest of the population as well.

Rise Of The Semi Vegetarian In The UK

The UK market for meat-free products such as tofu, sausages, burgers, and imitation chicken fillets was most recently put at £786.5m a year, up 7.7% from five years earlier. A further 10.3% increase is expected over the next five years, according to market research company Key Note.

But this boom in meat-free products is no longer being driven solely by vegetarians.

Just 6% (3.8m) of the UK population identified themselves as "mainly" vegetarian (eating fish but not meat) in 2011, and 3% (1.9m) as completely vegetarian.

So who is fuelling the rise?

Su Taylor from the Vegetarian Society says it's "people with differing motivations", which could be health, environment, animal welfare or just "trying something different".

They include "meat reducers" - people who may have bought in to campaigns such as "Meat Free Mondays" and are trying to reduce their carbon footprint.

IT consultant Alex Evans is one such follower, and says he now has "more meat-free days than not".

"The great thing with the campaign is that it only asks people to cut out meat one day a week, so I'm free to eat meat on other days.

"By cutting down on meat I now eat more vegetables as main meals, whereas before I thought vegetables could only be used as sides."

The UK's brand leader Quorn has a 56% share of the meat-free market, and is now marketing its food in a different way to a different set of consumers - omnivores.

Quorn is made from mycoprotein, a member of the fungi family grown and mixed with egg whites to create textured imitation meats.

Chris Wragg, the marketing director at Quorn, says its research shows 69% of UK households are "open to" a meat-free meal.

Quorn is now aiming at "healthy eaters", those looking to lower their cholesterol, and weight watchers seeking to reduce their fat and calorie intake.

"Historically our audience has been a vegetarian one that eats meat-free, and adds Quorn in to their diet, but increasingly we are seeing weight managers or slimmers, and healthy eaters."

Quorn contains palm oil and, even though the manufacturers say they use sustainable sources, we can only hope we aren't being lied to. Then there's all the non-food products which everyone, including many vegans and vegetarians, are using which is pushing up the demand for palm oil.

You can't turn cornfields into palm oil plantations so something has to be done about the palm oil problem now. If we wait until half the world is vegetarian there won't be any rainforests left. Animals living there will either be extinct or only found in zoos. There's another factor to consider as well.

Deforestation and climate change

Carbon storehouses
Mature forests store enormous quantities of carbon, both in the trees and vegetation itself and within the soil in the form of decaying plant matter. Forests in areas such as the Congo and the Amazon represent some of the world's largest carbon stores on land.

But when forests are logged or burnt, that carbon is released into the atmosphere, increasing the amount of carbon dioxide and other greenhouse gases and accelerating the rate of climate change. So much carbon is released that they contribute up to one-fifth of global man-made emissions, more than the world's entire transport sector.

Deforestation has such a massive effect on climate change that Indonesia and Brazil are now the third and fourth largest emitters of carbon dioxide on the planet. This dubious honour comes not from industrial or transport emissions, but from deforestation - up to 75 per cent of Brazil's emissions come solely from deforestation - with the majority coming from clearing and burning areas of the Amazon rainforest.

Indonesia is the world's biggest producer of palm oil. So I'm not jumping to conclusions. I'm looking at facts. Turning vegetarian to save a cow isn't helping animal welfare if it kills an orangutan instead. We need to be equally concerned about food animals and wild animals as well as carbon.
