Letting 1000+ people a day die is a non-destructive solution?

You could be killing 100,000 people a day if things go differently than you expect. Caution is in order.

Clearly no one you know is in the malaria danger zone.

Care to spell out the "100,000 people a day dying" scenario?

> and then it turns out to be a giant disaster The purpose of this is to stop the current giant disaster of 1000+ people a day dying from malaria. I can't help thinking that if this was affecting American middle class neighborhoods where environmentalists live, the mosquitos would be wiped out quicker than plastic straws.

I'm not suggesting that we don't address the giant disaster of millions dying from malaria. There is another solution right now: mass produce malaria drugs. How far down would that drive the death toll I wonder.

I actually wonder that too.

My impression is that malaria was wiped out in the rich world by methods that we now deny to Africa, like DDT.

I also believe malaria is a human only disease, so if you cure all sick humans fast enough, the disease dies out, and you're left with mosquitos that only suck blood and are annoying.

I suspect the problem with malaria drugs is not producing them at a factory, but getting them reliably into all sick patients in places where there aren't even doctors or roads.

Anyway, you claim this is a real solution: Is anyone actually ready to do this for real? If not, it's not a real alternative to the gene drive.

A problem is the discussion almost immediately derails into the eradication of all mosquitos, such as almost immediately happened right here. My understanding of these experiments is it is the eradication of particular subspecies of mosquitos, the ones able to transmit malaria, dengue fever, zika etc. And the difference is huge; wipe out a dozen subspecies and their ecological niches will be filled by other subspecie…

Correct, there are thousands of species of mosquito that do not feed on human blood. The question is whether a genetic weapon could be made specific enough to target only the blood suckers while sparing the pollinators.

The techniques being looked at only target a single species. To spread, it requires interbreeding between species which is rare, and for the the new species to out compete and spread, which is unlikely since the condition is fatal to the carriers of the genetic modification's next generation.

"There are over 200 species of malaria. Humans are infected by five. But birds, bats, lizards and antelopes are also hosts for malaria parasites." [1]

So no, unfortunately, curing all the humans will not wipe out malaria. The only real solution is to drive the mosquito vector to extinction, everything else is a temporary half-measure.

As a kid growing up in Malaria country I got yellow jaundice. Doctor told my dad that since I had had yellow jaundice I was "immune" to malaria. Its been 35 odd years since I have taken any malaria medication. Family members often get malaria once or so a year. A few years ago I decided to check to see if there were was any literature online with link between Malaria and jaundice. I couldn't find any papers online. N…

This reminds me of an interesting story. The host of The Portal podcast, Eric Weinstein went on the Joe Rogan show where he shared a story: he used to get very easily sun burnt. No chance of getting a tan. He'd just burn. Then, one day he took LSD and then stopped burning. Crazy story. No follow up study =).

The Psychedelics Encylopedia (3rd Ed, Peter Stafford), P73 info on using LSD to cure various physical ailments. Too long to reproduce here, suggest you get the book, you won't regret it.

Anyway, also shows before & after photos of of treatment of sever psoriasis with LSD and ritalin(?!)

This kind of experiment is called a gene drive, and there's a huge debate in scientific communities right now around whether it's responsible or not to use them, particularly around the mosquito problem. A professor of mine who works in the field was discussing this with us last week. The idea with mosquitoes specifically is that we can wipe out specifically the mosquito populations that carry most diseases. The deba…

> This is just my interpretation, but it seems like there is a sensible portion of detractors who simply want to derisk the experiment as much as possible by collecting more and more data. This is so infuriating. Many people will die during this extended hemming and hawing. Humans have driven countless important species to extinction with no thought, but we have to vacillate over a species that is responsible for mor…

In 1958 China wanted to eradicate 4 pests: the mosquitos responsible for malaria; the rodents that spread the plague; the pervasive airborne flies; and the sparrows which ate grain seed and fruit.

Guess what the result was: it exacerbated the Great Chinese Famine, in which 15–45 million people died of starvation. Because with no sparrows to eat the insects, locust populations ballooned, swarming the country.

Don't eradicate a species, before you're really sure it's not going to cause much larger problems.
