You're just plain wrong on this, Bill. I don't know where you're getting your information, but it certainly wasn't the book Silent Spring.

DDT is banned in the US, but it is not banned for pest control globally. The UN, which only got involved with establishing a worldwide standard in 2004, made a specific exemption for pest vector control.

From the Wiki on DDT:

"The Stockholm Convention on Persistent Organic Pollutants, which took effect in 2004, put a global ban on several persistent organic pollutants, and restricted DDT use to vector control. The convention was ratified by more than 170 countries. Recognizing that total elimination in many malaria-prone countries is currently unfeasible absent affordable/effective alternatives, the convention exempts public health use within World Health Organization (WHO) guidelines from the ban.[62] Resolution 60.18 of the World Health Assembly commits WHO to the Stockholm Convention's aim of reducing and ultimately eliminating DDT.[63] Malaria Foundation International states, "The outcome of the treaty is arguably better than the status quo going into the negotiations. For the first time, there is now an insecticide which is restricted to vector control only, meaning that the selection of resistant mosquitoes will be slower than before."[64]

Despite the worldwide ban, agricultural use continued in India,[65] North Korea, and possibly elsewhere.[20] As of 2013, an estimated 3,000 to 4,000 tons of DDT were produced for disease vector control, including 2,786 tons in India.[66] DDT is applied to the inside walls of homes to kill or repel mosquitoes. This intervention, called indoor residual spraying (IRS), greatly reduces environmental damage. It also reduces the incidence of DDT resistance.[67] ..." https://en.wikipedia.org/wiki/DDT

A passage that alludes to another thing that Rachel Carson- a trained aquatic biologist- got right: insects evolve to develop resistance to chemical pesticides, and the more frequently they're used, the more intractable of a problem that resistance tends to get.

I do what I can to avoid Wiki (fill in the blank). It's largely a popularity-based source. I do go to the citations and references and often find something useful that way.

Most posters in Internet disputes have away of avoiding anything, when it comes to backing up their claims with references.

I use Wiki as a place to start. The vast majority of their pages are uncontroversial, and well-referenced. When passages like the one I quoted are given with source references, I think it's sufficiently reliable to use for support.

Quite fair.

That's what I'm aiming for. Fairness, aka "maximizing my online unpopularity."

To crickets from the critics. It’s funny they love to spout opinions but when presented with facts they are silent.
