Description:
The pesticide DDT saved over ten million lives by killing disease transmitting insects. The
chemical has now been almost completely rejected worldwide as a tool for controlling
insect populations.
What factors caused the tide of opinion to turn against DDT?
What factors did Fred Soper believe led to the failure of global program to eradicate
malaria?
Should DDT be revived as an approved insecticide?
Be sure you understand the difference in scale between DDT use for agricultural insect
problems and use to kill malaria
carrying mosquitoes.
And be able relate Soper’s plan to
eliminate malaria to the ‘deadly triangle’ of pathogen, insect and host.
