Any Vegetarians/Vegans here?

Firstly, while it may be true that methane is second to CO2 in driving global warming, as it breaks down in the atmosphere relatively quickly, pound for pound it is 20 times more potent than CO2! Even NASA agree that it has an important role in climate change

I'm well aware of the science and you could have posted a much more recent link.

Granted, I do not agree that that the EGHE accounts for 100% of the climate trend, but let's play devil's advocate and go by NASA's numbers which put the contribution of Methane at or around 17-21%.

Global Warming trend 20th century: 0.6 degrees. Let's take the upper estimate of 21% which is 1/5th: 0.12 degrees (this number is meaningless since it's immeasurable so we'll round to 0.1 degrees).

So cutting methane to 19th century levels would theoretically reduce the global mean surface temperature of the Earth by up to 0.1 degrees, and there's no guarantees of it either.

Good luck with that agenda.

Now, as for farming on land unsuitable for crops, as I said before the emissions from grass fed beef are just as high as feedlot beef. So as long as some arable land is available then it will always be better to use the arable land for growing crops.

As for water and Australia, in the severe droughts that have happened recently the production of many grains reduced significantly, so yes it does have a problem.

It's a much bigger problem for crops then for livestock - do you understand this? Livestock can always be moved if absolutely necessary, whereas crops cannot.

People with thalassemia have a mutation which means their haemoglobin doesn't form properly, however that doesn't mean people can just eat some meat and use the haemoglobin from the animal. Haemoglobin, like virtually all proteins we consume, is broken down into its constituent amino acids in the gut which are only then absorbed.

Thankyou for once again showing you don't understand basic biology. Why you're trying to school us on it is beyond me.

Do you know what phenylalanine is? It's an essential amino acid and you can readily buy tablets of it as supplements wherever you like, it isn't regulated like say medications like pseudoephedrine. But did you know, and this is what it shares in common with pseudoephedrine, that you can use phenylalanine as a precursor for making Methamphetamine? See in theory you're right about amino acids, so long as we have enough of them we can just make whatever we like, but the problem you aren't recognizing is that even plants high in protein do not contain all the right amino acids!! Meat proteins contain the right amino acids, and even though they get broken down, they are put back together again. This isn't so with plant-based diets, they're broken down, and require a diverse pallet to put everything back together how our bodies need it.

One of the big problems people with thalassemia get is actually too much iron, which sounds rather counterintuitive. Essentially because they have less haemoglobin to bind iron in their blood and the patient then receives blood transfusions, they can then have too much free iron which can be toxic. Many patients are told to eat less meat, and vegetables containing lots of iron for exactly this reason. Of course because they have less haemoglobin they can also become iron deficient very easily if they are pregnant for example, which is why careful supplementation is required under the supervision of a doctor. A diet containing meat however is not required.

You should stop giving out medical advice to patients that you are not qualified to give it to, esp. as you refuse the acknowledge individual dietary requirements for different people.
