The half of emissions that are methane are the cow burps themselves, because their stomachs ferment grass and produce methane as a waste product.
Even if you want to quibble about the accounting of the other half, without cows grazing there would be way, way less methane produced.
Sure, 100 grams of raw spinach has only 2.9g of protein. But spinach cooks down a lot.
And remember, if you're trying to get to 50g of protein a day, you add everything together. Was your breakfast a slice of toast and some berries? You might have eaten like 5g of protein there, and you haven't even had an egg or anything that's a real protein. If you add an egg, that's 12g of protein at breakfast.
Ate a pb&j for lunch? That might have been another 10g of protein in that sandwich. Add a small side salad with some chickpeas and you're easily at 15g of protein.
Then for dinner, a serving of lentils is like 13g. Suppose you ate that with some raita and spinach, and you're easily at like 20g of protein at that meal already.
So that's like 47g of protein. Eat a handful of nuts or two oranges and you're at 50g of protein.
About half of the emissions from cattle are from methane; methane has about 80x the warming impact over 20 years that CO2 has.
Beyond that, cattle are slaughtered at 1 to 2 years old, while meat chickens are slaughtered at around 2 months. Cattle have worse feed conversion rates because they live longer.
So if you actually need a truck once in 5 years, would you really spend an extra ~$11k to avoid having to rent it?
Think of how much extra you'd pay for a rental service that dropped the truck off at your house, picked it up, and handled all the annoying things like filling the car up or cleaning it out.
Then, just add that into your calculations. That number is going to depend on how far you live from rental places and how much you value your time. Ballpark it.
Cruise ships are pretty big polluters, yes. Cruise passengers have about 8x the emissions that they'd have from a comparable land-based vacation.
But when people talk about ship pollution, they're usually talking about non-carbon pollution.
For example, ships often burn heavy fuel oil, which produces tons of sulfur dioxide, which causes acid rain, and NOX, which depletes the ozone and causes smog and asthma.
Cruise ships are bad for the environment, but there's honestly bigger fish to fry. Gas power plants are way, way worse for the planet.
'Cop city' is a police training center they're trying to build in a forest near Atlanta. People have been protesting its construction; the police shot one of the protesters back in January when they raided the camp.

Of course, there's also the times where we just make the research hard to do.
Like, we teach kids PEMDAS, but then don't actually follow PEMDAS in the original textbooks that introduce it and definitely not in common math or physics texts.
Like, you'll see 1/2√r in Feynman's lectures being written not to represent ½√r = √r / 2 as pemdas would suggest, but 1/(2√r).
Similarly, the original textbooks that introduced PEMDAS, if you read them, actually followed what you might call PEJMDAS, where multiplication via juxtaposition is treated as binding tighter than explicit multiplication, so 1÷2(2+3) would be interpreted not as ½(5) but as 1 ÷ (2 * 5), but they considered that so obvious they didn't bother to explicitly spell it out in the rules.
And now we have Facebook memes and tiktok livestreams arguing about what 1÷2(2+3) actually means.
Why do so many people think renting a vehicle when you already own one is cost effective, or a reasonable thing to do?
The 5 year cost of a fairly base 2020 F150 is ~49k according to Kelly blue book - that's fuel, maintainence, depreciation, loan interest, etc. The 5 year cost of either a 2020 Civic or a 2020 Chevy Bolt is $37k.
$12k / 5 years = $2,400/year. If you'd spend less than that a year, you'd be better off renting a truck when you need it and driving a cheaper vehicle daily.
You don't really have to.
You can just handwave public static void main, and only deal with primitives, then static functions, before introducing objects.
That's what they did at my high school. It's weird, and there's much better ways and languages to introduce procedural programming, but it's possible.

No.
The document lists symbols that violent extremists use, but explicitly calls out that not everyone who uses those symbols is a violent extremist.
The punisher skull is also in there, but that doesn't mean they're claiming every asshole with a punisher skull on their truck is a terrorist. Just that if someone with a punisher skull on their truck shoots up a mosque, that the punisher iconography is evidence that it was an act of right-wing militia terrorism.
According to https://www.mdpi.com/2076-2615/2/2/127/htm conventional feedlot beef produces 501,593 kg of methane per 1 million kg of beef, mostly from both burps and composting manure. So that's about .5 kg of methane per kg of beef.
1 lb of methane is 84 kg CO2e; that is to say over 100 years 1 kg of methane warms the planet the same as releasing 84kg of CO2. So every kg of beef produces 42kg of CO2e, regardless of any quibbling about the CO2e of agricultural waste fed to cows.
By contrast, googling quickly the quoted CO2e emissions per kg of chicken is 18.2. Which is, of course, subject to the same quibbling.
