The eradication program ended not because of any environmental concerns, but because it did not work. The mosquitoes had grown resistant to insecticides, and the microorganisms that cause malaria had become resistant to the drugs used against them. In many areas the numbers of cases of malaria greatly exceeded what it was before the effort was started. If events had been different, if DDT had not been used heavily in agriculture and there was no shortage of funds the outcome might have been different. Malaria might have joined smallpox as a disease that had been eliminated from the face of the earth. Unfortunately, such was not the case. As early as 1967 it was clear that the effort had failed, and in 1972 the official policy shifted from eradication to control of malaria.
The easily found evidence for worldwide outbreaks post-spraying are widely available and the newer methods of "control" are ineffective wherever they are used.
Don't think I am speaking with the voice of compassion here but only to ask if you have more data you might like to share or are you just Googling?
