You can argue, sure. But people have actually studied this, and you're factually just plain wrong.
You've seen the centralized waste. But you haven't picked through a neighborhood's worth of trash cans to put that centralized waste into the larger decentralized context.
The government spends hundreds of billions on infrastructure every year.
Have we fixed potholes permanently?
Also, $8 billion is a bit less than $24 bucks per person in America. Do you really think $24 is enough to permanently solve hunger in a country? Do you think that another $5/person is reasonable, a few years later?
Almost half of food waste is people buying food that they let go bad before they eat it.
That's substantially a price problem, in that people are more willing to let a cheap banana spoil than a prime rib or lobster. Food being cheap makes people more willing to let it expire.
But fixing residential food waste by making food more expensive would make hunger worse.
Keep in mind: the largest source of food waste is residential. The second largest source is restaurants.
Food waste is bad for the environment, sure. But the rent being too damn high is a lot more of the reason why people go hungry than me letting a bagged salad in my fridge go bad.
LD50 is specifically a dose that kills 50% of the subjects.
Lower doses can kill, just less than 50% of people.
More than 1200 mg of pure THC, or 1200mg of cannabis leaves?
Those aren't even remotely the same thing, in the same way that 12oz of beer and 12oz of everclear are very different, or 1g of pure nicotine is very different than 1g of tobacco leaves.
Not to mention, LD50 is about a single dose. There's a big difference between taking one shot an hour for 16 hours straight, and chugging 16 shots in one go.
16.5 mg is 16500 μg. So a 70kg person would need over 1 million μg.
According to https://www.trippingly.net/lsd/the-lsd-dosage-guide, 25 μg is where visual effects start.
700 to 1000 μg. Full out-of-body experiences. Synesthesia more likely. Religious imagery often strong. Entire loss of rationality, lack of ability to walk or interact in any meaningful way.
1500 μgs+ Experiences may be similar to DMT but extended. Basic body functions are challenging. Vision is consumed by hallucinations. No sense of self remains. Audio hallucinations may be strong. Standard reality no longer applies. Merging with objects likely. No type of rational thought left.
A deadly dose is around 800x higher than that. You wouldn't be as high as a kite. You'd be as high as Voyager one.
Also: notice the LD50 for vitamin D is 37mg/kg.
Based on https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8709011/, a therapeutic regime for very low vitamin D levels is taking 6k IU per day for 3 months, or 50k IU once a week for 2 months.
1 IU is 0.025 μg, or 0.000025 mg. 50k IU is 1.25 mg.
I buy bottles of 5k IU vitamin D pills. Each bottle has 90 pills. That's 11.25 mg of vitamin D per bottle. I'd need to take well over 200 bottles of these pills to have a 50% chance of dying.
Yes, an objectively small amount of purified vitamin D will kill you. But it's quite safe in practice because the environment only has objectively tiny amounts of the stuff. Even high dose pills contain a tiny amount of the stuff.
Keep in mind: a single extra strength Tylenol is 500mg. A standard dose for a headache is 2 pills, or 1000mg.
Weed gummies come in doses of 1mg to 100mg. 1mg is a microdose people might take for mild pain or stress, while 50+mg is a dose for cancer patients often take. A standard dose for occasional recreational highs is 5mg; they recommend first timers start at 2.5mg.
LD50 compares things by weight, rather than dose. By weight, THC is slightly more toxic than acetaminophen. But in terms of the number of therapeutic doses it takes to kill you, it's way, way safer.
LD50 is usually determined using rodent studies. How much Vitamin D causes an overdose in half of a population of mice?
The dose makes the poison.
And with drug safety, in practice LD50 is less important than how close a therapeutic dose is to a lethal one. If a drug takes 2g/kg to kill you but you need 1g/kg to work, that's way more dangerous than one that takes .02g/kg to kill you but only needs .0002g/kg to work.
So you have $35,000 left to account for.
How much did you buy your car for, and how much can you sell it for after a decade? Depreciation is one of the larger costs of car ownership. Assuming you financed it, there's also the cost of interest on the loan.
Also registration and other state fees.
This is facile.
According to Microsoft, about 70% of security bugs they see are memory safety issues.
Yes: if you introduce memory safety, there's still those 30% of security bugs left. But, well, I'd rather worry about 30% of issues than 100%...
Similarly, I use libraries that eliminate SQL injections unless you really go out of your way.
