A proposal to improve conditions, for a change:
Tbh, I'm not a vegetarian, but eating less meat in general would be better for the environment.
In terms of calorie-per-acre of land, it's more efficient to grow crops than raise cattle.

I agree on both counts, and I'm not a vegetarian myself.

Here goes another interesting snippet from the article:
Another alternative is to feed animals on a diet less to the liking of the archaea. This can be partially effective, says Phil Garnsworthy, who specialises in dairy cow nutrition at the University of Nottingham, so long as it continues to allow the animals to go on producing milk and meat.

“You can probably reduce methane by about 20-25% by altering diet,” he says. One study by researchers at the University of California, Davis, estimated it might be possible to reduce global methane emissions from cows by 15% by changing their diet. But Garnsworthy believes more may be possible. In the UK, he says, farmers mainly use grass-based silage.

“If you changed just to maize-based silage you might see a drop in methane production of 10%.”

The more fibre a cow eats, the more methane it produces, but adding legumes and various oils such as linseed and soya to their diet can be helpful, adds Sinclair.

“Better quality feeding makes animals more productive, and more productive animals produce less methane,” he says.

Another interesting research that shows that technology can help save nature and take us out of this problem:
Crops under solar panels can be a win-win
In dry places, photovoltaic shade can even reduce water use.
by Scott K. Johnson - Sep 5, 2019 5:40pm BRT

"Agrivoltaics" studies like the one pictured here in Massachusetts are finding many crops that pair well with solar panels.

Solar panels might seem like they’re in direct competition with plants. One is catching sunlight to do photosynthesis, the other wants to take it to push electrons. Surely Highlander rules apply, and there can be only one on a plot of land, right?

In reality, it’s not a zero-sum game. Some plants will burn in direct sun, after all, and so there are plenty of food crops that would be happy to share their space with panels. And as a new study led by the University of Arizona’s Greg Barron-Gafford shows, the combination isn’t even necessarily a compromise—there are some synergies that can bring significant benefits to a solar-agriculture
.

This pairing can be even better with solar panels and dams, preventing evaporation and cooling the panels at the same time. There could even be a combination of the three, agriculture islands on top of lakes, under solar panels that would feed the system with energy. Windmills can be a part of the system as well, as the power structure would be there and there would be plenty of space for tower installation.

Aquaponics is another efficient food system.
Fish and crops at the same time. :sweet:

Yeah, that would make the system complete, with power and distributed stations to tend to the crops and to the fish :thumbsup:
