After several million avoidable cases of malaria, unfortunately:
The World Health Organization (WHO) has reversed a 30-year policy by endorsing the use of DDT for malaria control.
The chemical is sprayed inside houses to kill malaria-carrying mosquitoes.
DDT has been banned globally for every use except fighting disease because of its environmental impacts and fears for human health.
WHO says there is no health risk, and DDT should rank with bednets and drugs as a tool for combating malaria, which kills more than one million each year.
"The scientific and programmatic evidence clearly supports this reassessment," said Dr Anarfi Asamoa-Baah, WHO assistant director-general for HIV/AIDS, TB and Malaria.
....A potent insecticide, DDT fell into disrepute with the publication of Rachel Carson's Silent Spring just over 40 years ago.
The book showed that widespread, indiscriminate use of DDT and related compounds was killing wildlife over vast tracts of North America and western Europe.
And, twenty-two years ago Edith Efron exposed Rachel Carson's claims as a crock in her The Apocalyptics. That it was a socialist fable designed to hamstring American industry, and had very little scientific validity.
