Lild UK calls for mandatory plant-based protein targets! This is exactly the sort of thing I was talking about in my piece on grocery stores—it’s going to be extremely difficult to push consumers to replace animal meats with plant-based via nudges alone, we need more comprehensive strategies.

Different demographic groups eat different amounts of meat. By far the biggest demographic factor that predicts beef consumption in developed countries is gender. Men consistently eat more meat than women.

If we want to get hard-core meat-lovers to buy alternative proteins in supermarkets, the biggest factor will likely be price: they are willing to pay far less than flexitarians are.

I didn't say food crops, I said factory farms.

It's far better than 1000x than a city, which is what the book was trying to claim!
What's important when thinking about environmental issues is placing these numbers in context of other energy/water demands. AI uses less water than gold courses, lawns, and FAR less than factory farming.

I'm interested to see where this goes: Big Meat uses the ideas of "free-range" or "family farm" as rhetorical shields when it's convenient. but fights those ideas when they want better welfare reforms.

Factory farming representatives are getting angry that higher-welfare meat brands are allying with animal advocates to lobby for better welfare standards for farmed animals in the US.

New study proves (again!) that animal-free diets are the best for the planet: nutritionally sound vegan diets nearly halved the carbon footprint of omnivorous diets

Big Meat is just as bad for the climate as Big Oil. A new report reveals that industrial meat companies emit more greenhouse gases than fossil fuel corporations, such as Shell and ExxonMobil.

Interesting — a new study shows that exposure to appeals to plant-based eating increases defensiveness and that people with anti-social personality traits are more likely to get defensive.

The new EAT-Lancet Planetary Health Diet report is crystal-clear: we are eating far too much meat than is sustainable.
We need a food systems shift: more fruits, vegetables, grains, and plant proteins. Fewer animal products. Period.

This is extremely poor framing. It is not a "taste for soya" destroying the Amazon, it's a taste for meat. The VAST majority of soy grown in Brazil is due to animal agriculture, but your article never mentions this fact.
Your readers are walking away with a poor understanding of this issue.

Despite the fact that animal agriculture is a huge driver of environmental destruction (causing both deforestation and GHG emissions), mainstream media outlets rarely address it. This report from Sentient shows that less than 4% of climate articles mention meat as a cause of climate change.

This new report on the connection between food and species extinction is astounding.
If we want to stop our fellow Earth creatures from going extinct, we need to change our diets and stop eating so much meat.

Sub-Saharan Africa is the region that's expected to see the most growth in farmed animal populations over the coming decades.
Factory farming corporations from other countries like JBS are eyeing the region for growth -- which can harm animals, the environment, and locals alike

Because of how small chickens are (and how popular it is to eat them), nearly all of the factory-farmed land animals in the US are chickens.
This is often called the Small Body Problem: as people eat smaller animals, they need to eat more of them.
