@U_Stormcrow sorry this is a misunderstanding . I thought your arguments was about animal factory farming. We do need agriculture on reasonable large scale to provide food. Yes true, we don’t grow wheat and such in a large scale here and import a lot of grains and lots of tropical food too.
We have more grasslands for cows and free range chickens than we have agricultural land for crops like potatoes, beets, beans, brussels sprouts, cowl, corn etc. And the farmers use part of the agricultural land (corn an sugar beet) for cows too.
Our nr 1 NOx polluting factory in the Netherlands is the one that produces artificial fertiliser. Lots of land has become so poisoned that it became hard to grow food on it. So I would welcome it if Europe / our government decides it is prohibited to poison our land any further.
The greenhouses are not very polluting anymore if they use earth warmth, solar and wind energy. A lot of their ‘waste’ is recycled nowadays. (eg the leaves of bell pepper and tomato plants are used to produce board in the building industry) . If they change to modern and environmental positive techniques greenhouses are a way to produce lots of food and bio-based materials in the future.
Edit spelling
The same theories underlie factory farming, whether animal or vegetable. Its large scale monocultures, altering the lands to maximize suitable space and importing resources (feeds, fertilizers, water, etc) to support the continued drain on the area's ability to replenish itself, while concentrating byproducts for disposal or removal.
It allows a farmer (of whatever type) to concentrate expertise - that is, to be very very good at a thing - and to control for most variables, since so much is already imported to the property. The alternative, a balanced small scale system, generally involves a "farmer" who is passably good at a lot of things, desperatly trying to maintain a balanced ecosystem in the face of chance. Nature herself does a decent job of it planet-wide, but locally, not so much and not so often.
Lets use my own property as example. My incubation (mechanical) and culling allow me to maintain a balanced number of birds, providing (on average) whatever number of eggs per day I desire. I maintain very strict biosecurity. But if a wild bird were to bring a disease which ravaged my flock? It would take most of nine months to rebuild to current levels if I were to lose 75-80% of my birds.
In two years, NONE of my birds - ducks or chickens, have ever successfully incubated a clutch of eggs. I've sacrificed over 200 duck eggs to the effort this year alone, and a similar number of chicken eggs. I have an abundance, which I sell and sometimes donate, I can afford to do so - I'm a hobbyist, supported by other means - but very few living much closer to the margins could afford such persistent losses.
We had a cool fall. Last week, our overnight temps were in the 70s. This week, we had a hard freeze. All of my citrus, my blueberries, some of my other fruits had all been tricked into bloom by the early cold, followed by a warming trend. The hard freeze may have decimated this years production - I won't know for months. If I operated at the margins, I'd have been wiped out.
Two years back, in our (traditional) rainiest month (avg 8+ inches), we recieved just 1/8" of rain on property - destroyed more than 100# of seed I couldn't keep wet after planting, and altered the entire biome of my pasture - only the fact that I deliberately "cultivate" a polyculture kept me from losing the whole thing, and allowing invasives and native opportunist species from moving back in (anda LOT of weeding).
There have been other setbacks. I had to cull my only Rooster, more than a year ago, for reasons. My only doe dropped two boys this winter, giving me four male goats (the kids will be wethered next week), the sire goes to freezer camp "soon" - though I haven't a clue how I'm going to put him down to butcher him yet - I can't even catch him. or hang him up to do the deed.
I don't have the meat rabbits yet, who knows what "fortune" I will have with those.
...and none of this is unusual, its just chance playing out. Modern society, resources, etc allows me to suffer these setbacks in ways I could not if I also needed to produce all the feed for my animals and most vegetables for my my wife and I. Last year's potatoes, sweet potatoes, and onions were a bust, as was the garlic. This year, the onions, leaks, garlic are all doing spectacularly. I'll know about the asparagus in a year or two - it takes a long while establishing itself - but I have concerns.
I could - I'm certainly trying - to build a largely self sustaining ecosystem on the grounds, and I've got a lot of ground (albeit with similar soil characteristics) to play with. But its a precarious thing - any 50/50 roll of the dice can easily throw it out of balance. and has, routinely.
