Grass that is deep rooted to cater for the infrequent rainfall and resistant to burning that happens on occasion even in the best managed grassslands. That ecosystem depends on ruminants (buffalo replaced by cattle) to transfer nutrients and alternate grazing systems to allow certain grass and other species to grow and prosper.

To produce non animal derived low protein low concentrated foods for a population of 6.5 billion people and increasing will need more land not less. Ploughing up grassland to grow crops for humans to need will lead to increased carbon release. Not all animals are kept purely for meat production. The dairy industry is an important part of irish and global food production. In Ireland this sector is dependant on grassland. Irish grassland systems are extensive and not intensive. What do you propose that a) farmers should or grow produce and b) what are people going to eat?

Sure there are areas where it doesn't make sense to grow something and put animals there to feast and grow, overall is meat just not as effective as a plants.
gozunda wrote: The calories produced by plants have on average less protein and less calories. Therefore we have too eat more of them to feel full. Many diets work on the principle of advocating eating protein as it makes you feel fuller for longer. Meat is very effective in providing a good quality protein source. Of course meat is usually eaten not on its own but with vegetables as well. This obviously provides the basis of most balanced diets in this country.

It's worse for all the animals up to lamb which takes in 54 grams of protein which can be consumed by humans. Humans could just eat that protein themselves. I assure you, I've researched this. There's no way to spin it that farming and eating meat is more efficient than eating plants. It doesn't work from an environmental perspective and it doesn't work from the protein perspective you brought up here.

Growing crops to feed to animals is a really inefficient use of land compared to growing crops to feed to humans. Therefore, growing crops for humans alone , old require LESS land worldwide.

In Ireland only small percentage of land is good for cereals. However in practically all areas of Country 30 years ago most farmers would have grow a few spuds/turnips/oats etc. Now just cattle/sheep.
Going by an IFA definition Irish grassland system is extensive. Reality is most are intensive and progressively more intensive.

gozunda wrote: No it is not 'really inefficient" to grow 'grass' as a crop as we do in Ireland. Our climate and soils are most suited to grass growth. We can't eat grass so ergo we manage livestock who can eat grass. And it's not just meat that is produced but a vast range of dairy products too! Seriously that is not too difficult to understand.
gozunda wrote: Crops and vegetables are less rich in protein (which makes us feel full) and calories. Therefore we would have to use lots more ploughed up grassland (releasing lots of sequestered carbon) to produce more crops to feed everyone (and btw Irish soils in the main are not suitable for this type of production)
gozunda wrote: Meat and dairy products are a high quality foodstuff. In ireland it is profuced from a grass land based agriculture. There is nothing wrong with eating meat unless you have an philosophical or ethical objection to doing so . And that's fine - don't eat it but don't tell others what they should do either.
gozunda wrote: In the absence of high quality protein such as meat we need to eat lots more plant protein to obtain the same nutrients and calories. Huge areas of grass land would have to be turned ovet to Horticultural production to make up this deficit.

Yeah the use of dairy and other animal products helps. But the point stands that growing animals for human consumption is less efficient than simply growing veg crops for human consumption.
Forget making you feel full. I'm taking about calories involved in terms of goring crops for second order consumption by humans. You need fertiliser, Machinery, fuel, pesticides, water, transport, just to grow crops for animals to eat. Then you need to farm the animals for humans to eat.
gozunda wrote: » If you don't feel full - you will eat more. Therefore you will need more plant based foods. And in Ireland our agricultural production is largely based on calories from grass which are useless to us but transformed into edible protein through dairy and livestock production.

Howevet this is not possible as Irish soils and our climate are NOT suited in the main to the growing of 'cereal crops'!
And without organic wastes from livestock what are we going to use exactly to help grew these large areas of crops? Artifical fertilisers you say? Sorry no can do because they cause even more carbon release into the atmosphere.
Our systems are extensive ie based largely on grass production and are not thereore intensive. Teagasc also provides the same definition. Are they wrong as well?

Proteins keep you longer not hungry but the same you experience with whole wheat grain as the body takes longer to digest it and a constant stream of nutrients is given and blood sugar stays high.
